Sdam is so brutal

35 Upvotes

I not only have almost zero autobiographical memory but also severely deficient long term semantic memory. Essentially, no memory of my past after the past ~2 weeks.

It’s actually so brutal because I’m in college and have absolutely no personal stories to tell besides ones I’ve written down or ones I make up (but this really lacks authenticity). No sympathy for it either because my family assumes I’m making this problem up and nobody considers it a real issue.

My networking chats suck, I find it hard to make friends and talk to people, and remember any concepts I learn. My middle class family is paying 90k/yr for a top ivy league undergrad (they pushed me into it, not really my fault they’re paying this much), but I feel like I can’t take advantage of any of the opportunities because I’m so vastly intellectually inferior to my peers. It’s not an IQ issue but an issue with memory.

Wasn’t a problem in high school because I could memorize everything right before the test but is a major issue in college where everything is about networking, socially connecting with others, and telling stories.

People don’t get it

13 Upvotes

I have aphantasia and I’ve only read about SDAM last month, but seems like I have that too. When I talk to people about either, I almost always get an answer like “Is that so rare? It’s not like I can replay random memories in my head like it’s a movie”. When that happens, I don’t really have an answer to explain the difference between ‘normal memories’ and my sort of conceptual memories. How do you deal with situations like that? I’d love to have an answer that explains it better.

Almost no memories

2 Upvotes

Hi, everyone. Bipolar 1.

I am just coming out of a few months long severely depressive episode that followed a manic-psychotic one.

Coming out of it sounds good. However, this depressive episode was eye opening because I discovered I have SDAM (Severely Deficient Autobiographical Memory). I cannot remember the entirety of my life. Essentially, I have zero long term memory, almost no episodic memory, and broken semantic memory.

Almost 6 months ago I moved to Barcelona for work (I am a programmer) and, for the love of me, cannot learn even the closely surrounding area of my flat.

During my manic episode I lost my job. I am still in Barcelona, living on the final stretch of my savings. When that is over, I need to return to my home country, leaving my fiancée here.

My memory issues span beyond SDAM. During the worst of depression I had major cognitive issues and almost zero working memory. Depression is lifting, most of the issues stayed. Job search is not going well. I feel like I lost most of my programming skills without having practicing it. There is a single flipside. My traumatic flashbacks fade very quickly.

How does one live without memories?

I went through the autism and ADHD criteria one by one. For me, everything that looked like it applied turned out to be my cognitive profile.

4 Upvotes

I have total sensory aphantasia, SDAM, and no inner voice. I've been trying to work out whether I also have autism or ADHD — whether the traits applied to me.

This isn't a formal study, just my own experience and a question for others. I'm not suggesting it applies to anyone else.

Autism

Social communication. I can read non-verbal cues. I notice them in the moment, and then they're gone. No retention, no replay, no comparing. For me, that's SDAM showing up in a social context, not autistic difficulty in reading cues.

Preference for routine. I eat the same food, take the same routes, do things in the same order. But not because change is distressing. It's because I can't imagine a different meal, or a different route, or a different way of doing things. There's no imagined alternative to be drawn towards. So I stay with the familiar. For me, that's aphantasia — no forward projection, no gustatory imagery — not autistic rigidity.

Distress at change. I don't have it. I wasn't holding the original in mind, so there was nothing to disrupt. That's the absence of forward projection.

Environment. I need things in fixed spots. But that's because I can't hold their location in mind. The spot does the remembering. That's spatial memory and working memory. And I can't bear silence in a room because my mind is silent. External sound gives me something to process. That's aphantasia and anauralia.

Sensory overwhelm. I can get overwhelmed by external sensory input. But the cause isn't a threshold difference. It's that I have no internal escape route. No imagery to retreat into, no inner voice to focus on, no replay to occupy the mind. So I stay fully exposed to whatever's happening. That's aphantasia and anauralia, not sensory sensitivity in the autistic sense.

Special interests. I don't have them. I have problems that need solving. Once it's solved, the drive stops. That's not a special interest.

Repetitive movements. A few unconscious ones. Which is common to most people.

ADHD

I don't relate to any of the ADHD traits. No distraction, no losing the thread, no forgetting what I was saying, no losing things, no time blindness, no organisational chaos.

The pattern

For me, every trait that looked like autism turned out to be one part or another of my cognitive profile. Some of it was SDAM. Some was aphantasia. Some was anauralia. And the ADHD traits weren't there at all.

I don't know whether this is common. I suspect some people with SDAM and aphantasia are told they're autistic or have ADHD, or wonder about it themselves, because the behaviours look similar from the outside. But for me, the mechanism turned out to be different. It's not a failure to filter or regulate. It's an absence of internal content to work with.

I'd be interested to know whether anyone else has been through a similar process of working this out.

What this means in practice

This is my own experience, and I'm not seeking an assessment. But I think about the people who might. Someone with this profile who doesn't know what they have. A child struggling at school, whose parents are told it's autism, or ADHD, or just behaviour. The criteria are behavioural. The behaviours are there. But the mechanism — the absence of imagery, replay, inner voice, and forward projection — isn't something a clinician would see, or necessarily know how to ask about.

I don't know what would happen if someone with this profile went for an assessment. I haven't had one. But my guess is that the behaviours would fit the criteria, and the mechanism wouldn't be seen. Not because the assessor was careless, but because the framework is built for minds with internal content, and this profile doesn't have any.

For a child, that could mean years of the wrong support. For an adult, it could mean a diagnosis that never quite explains anything. And in both cases, the real profile stays invisible, because nobody has a name for it.

Difficulty remembering emotions

10 Upvotes

Curious whether this sounds like SDAM or something else...

To put it simply, when I'm happy I can't recall being sad, and when I'm sad I can't recall being happy. I can accept it logically, especially if I write something down at the time then look back on it later, but it feels like looking at someone else's writing - it's hard to really accept that it was actually me (again, logically I can accept it, but emotionally it just seems inconceivable.) The more intense the emotions are, the more this seems to happen.

Anyone else have trouble with whether or not they're autistic/relating to diagnoses and other traits about themselves?

9 Upvotes

I came across SDAM while doing a prescreening survey for my university's mandatory research study participant program. I checked "no" because it didn't immediately connect with me but today I thought back to it and wanted to try and post something to see if other people would relate.

Also, a little note: Sometimes I say that I "have never" or "I have always." It's important to keep in mind that I might actually have felt differently in the past (as I sometimes learn when looking at what I have previously written).It just feels as if whatever I feel now has always been true

I've been diagnosed with autism in my early teens but have never connected it to who I am. I think it might be because I can't remember what would be relevant in order to relate myself to the diagnosis. It says in the report that I have sensory sensitivities and struggle with social connections, but from my first-person perspective I don't recall any moments where I found a sensory thing overwhelming or where I wanted to connect with people but couldn't. For a while I thought that I might fundamentally lack social drive because I couldn't remember wanting to talk to people + don't feel what I think I'm supposed to about people who aren't right in front of me. But then as I carried that thought through my life I encountered scenarios where the only logical conclusion was that I did care about people (even if I couldn't recall caring about them before) and that got tossed in the bin. There was also a time where I thought that I was alexithymic, but ended up deciding instead that I could identify my emotions in the moment and just couldn't remember any of the ones I'd had previously.

What I find most presently frustrating is the sense of confidence that it feels like other people have about their diagnosis + about who they are? Vs it feels like I'm waking up today to a life that I haven't lived and can't therefore be so certain about who I am. It's very tempting to assert that I'm not autistic (despite that probably being true) because that feels like something that applies to someone else (who is technically also me). It's not like autism is a state of being that you can feel on you at all times after all.

Also I don't have a very good understanding of what makes memory "autobiographical" and thought that that just meant like, it being about myself from my perspective. It seems contradictory that I remember how in first grade I had trouble with writing essays because they'd ask questions like "recall a time when something made you sad" or "write about how something you did to make someone happy lead to them doing something in return." I could never think of anything to write about. The same was true of the essay I sat for high school admissions where the question was like, "describe a woman you look up to and how that has affected you." I remember telling my mother that I hadn't been able to write more than a sentence or two.

I also remember when I was seeing a therapist to get diagnosed with gender dysphoria and he noted that I never seemed to talk about it with an appropriate level of distress. He attributed it to autism, but I think it was more because when I say that something is usually distressing to me it takes a good deal of effort to reconstruct whether that's really the case or not. And I have assumed that that was the case for everyone else too; like that they can't know anything about themselves without reasoning it together using what's most likely true given their behavior.

+despite not being able to remember the emotional details of things I have a pretty vivid memory of more conceptual things? Like, I can remember the ways crabs scuttle around on the marshes of Cape Cod (with the salty air and the grass tickling your feet) or the feeling of a chilly day in autumn (with the smell of the leaves and the wind on your skin). I just can't remember what it was like during major events or at any more specific time. I'm also fine at imagining what might happen in the future.

If I do have SDAM it hasn't spared me from developing PTSD. Although, the only flashbacks I get are somatic.

How a Memory Changes: Sharing My Message History Where I Continuously Recall One Event

12 Upvotes

I have SDAM & aphantasia and I wanted to share my message history that tracks how I recalled a troubling experience that happened April 2026. In each of these messages, I am trying to explain what happened to friends, family, and acquaintances at varying times after the event, including "day after," "1 week later," "1 month later," and now. I wish I complained more to more people because I find it interesting how you can see my SDAM & aphantasia go into effect and transforming how I viewed this experience / how I explained it to others. Messages below I directly copy and pasted from when I originally sent them.

Short summary of event: I cut off a friend of 4 years who was also my roommate for 1 year. Her negligence on our lease led to a lease termination fee of $5k which I found 2 weeks before moving out of the country. I was upset at having to shoulder all the work finding a new tenant and clearing out the apartment alone.

───

Warning petty thoughts, genuine anger, and many spelling mistakes. Really sorry if some come off as rude! You can tell in some of these I was deeply hurt

A day after the event (April 30th)
"Tldr my roomie and prev friend of 4 years screwed me out of like 5k because of her disorganization and inability to keep on top of things. She told me incorrect info about our lease, causing an auto renewal, and then we had to pay a termination fee to get out. Even worse is that she constantly made the situation worse every step of the way. I took on the brunt of finding another tenant since she was apparentlv too busv to prioritize this. She moved out 2 days before the 30th, leaving a shit ton of her stuff behind for me to dispose of. She constantly fed me incorrect info about the progress of our lease termination. She didn't clean her room, forcing me to scrub all her gunk. When I asked why she left so much stuff she only deflected that it was for the next tenant (broken glasses and burnt pans???). When we finally got our termination verdict, she wanted to dispute the charge and drag it out longer (shut it down immediately) Sucks cause she genuinely was a good friend for those 4 years, so wtf happened??"

1 week after (May 8th)
"Tldr, X screwed me out of 5k because of her disorganization and inability to prioritize. This caused her to feed me incorrect info about our lease, leading to an auto renewal, forcing us to pay a termination fee. We were 2 weeks away from moving out when we learned. Even worse was that she made the move out difficult every step of the way. She constantly gave me incorrect info about lease termination progress. She was apparently too busy to help with finding a new tenant, forcing me to post the apt and clean and coordinate meetings (despite me voicing my stress and the fact i still had a final due). She moved out on the 28th and, without telling me, left a crap ton of her stuff to dispose of. She left her room in disarray, forcing me to scrub and clean her gunk. When I asked why she left so much stuff, she deflected and said it was for the next tenant (burnt pans and broken glasses??? 😭). When we got our termination verdict, she wanted to dispute and drag it out longer (shut it down immediately). Never in this process did she apologize for anything."

~1 month after (May 25th)
"[...]Her bf helped her move back to west coast, but I kinda felt a little bad for him since she didn't plan anything. Didn't have the boxes to pack, wanted to keep all her items (even things she could throw out), didn't call to ask if the shipping company can ship her items etc. He had to pull everything

In the end she wasn't able to pack everything. I woke up to an apartment that was still full of stuff but her gone. When I messaged she said something like "I didn't leave much stuff?" I spent pics "that thing is yours right? And that?" I told her I was planning to throw my own stuff. No apologies, just "Ok, just trash my stuff then." The lease mess up was just some countries have different lease laws. My exfriend lived in this apt building for about 3 years so I trusted her about the apt. A doc came in "lease renewal doc" and i told her "i 100% am not going to renew" and put it on her desk since her at the time might be renewing. I asked about the doc 1 month later and she said "no worries about it. By not signing, we are telling them we are moving out." Turns out that's not the case and our lease auto renewed for another year. I found out it auto renewed 1 week before we were moving out. It also turns out exfriend only read doc 1 week before moving out also (like I should've also read the paper but I thought I could trust her).

I was stressed about it and tried everything to find new tenant to take over. I still had final paper too, so I told her I was stressed and asked her to help finding a new tenant. She said "sorry, I'm out that day" and in the end I was the one that cleaned the apt., posted it online, did the viewing, arranged with office for lease transfer meeting. Idk what she was doing but she was out 90% of the time even though I kno she didnt have finals etc. When we finally got our lease termination verdict (April 30th), she tried to contest it. Told me she didnt want to pay even tho I asked her earlier which decision to take (lease transfer or lease termination) and she responded with "just choose whatever"

5 Months After (October, now)
"We were friends for 4 years and roommates for 1 year. What happened was she messed up something on our lease which caused it to auto renew for another year. This led to us both paying $5k in order to terminate our lease contract. I found out 2 weeks before I was moving out of that country that our lease auto-renewed and that my roomie essentially lied (even if inadvertently) to me about our lease. Coupled with other issues (like how she moved out without packing her things and left me to dispose and clean her stuff) let's just say I was not having it 😅."

-----

My personal observation is that as my memory got unreliable, I started using quotes directly from messages and emails that were sent to me to piece together what happened. "1 month after" became much more of a story. We have multiple characters, a timeline of events, dialogue (quotes), and a lot more detail as to what happened.

And then "5 months after," I guess my SDAM nuked it? A lot of the details got smushed down to "yeah, that sucked and I was really angry." It became a lot less personal. It looks like I'm summarizing something that happened to someone else. There is no more of that "She did that to ME!" and it became much more "I can't believe something like that happened."

I hope this was somewhat intriguing. If any of you have moments in your life where memories got compressed, please do share!

Ufhshfhshfhshsh. My information encoding and retrieval is soooooooo weak. I’ve used aphantasia and SDAM to name this type of severe lack of intelligence (not in a self-deprecating kind of way but in a “reality matches and this is a pattern of behavior that folks witness regularly” way”) and it heightens the embarrassment into shame when I’m coupled w the regular mistakes I make and the sheer amount of times I just blank socially. I FEEL LIKE A VOID. I made a mistake of introducing myself incorrectly - I’ve been at this job for nearly 3 years, and yeah I’m bottom of the barrel and verticals have changed, but my supervisor has the team we’re apart of IN HIS SIGNATURE. and somehow by some incredible degree of nonprocessing, I named myself as being apart of a team that I’m not in a meeting w the entire office.
It’s deeply embarrassing.
Anyways. That’s a microcosm, a very tiny example that ties into a larger knowing of “I’ve been here for a long time and yet I have little institutional knowledge because I don’t actually process information.” and there’s so ons and so forths here, but really just needed this site of embarrassment named. And neeeeeeeed to figure out how to sit with this shame. I want to hibernate. Shared experience and advice preferred over reassurance, although I’ll take all 3 and more.

I am so afraid of reality

11 Upvotes

Every time I'm reminded of the fact that I'm real and that my decisions are actually affecting my reality, I start panicking. I get so scared that I want to dissociate even more, I find more ways to escape and even that doesn't feel like enough. I feel like my heart rate is faster even when I'm resting, i can't think at all and I need to take a rest just from the fear itself.

I don't know what to do because I have to live in reality and do real life things but I can't because I'm so afraid of everything. Does anyone have any experience with something like this? Were you able to manage it or figure out a way to deal with it?

Thanks for reading through my incoherent thoughts

Hello, I have found my people.

17 Upvotes

I didn't know about SDAM (Severely Deficient Autobiographical Memory) or Severely Deficient Episodic Memory (SDEM) whatever you want to call it, until just a few hours ago. I came across it after some research into myself and why I am the way I am. I have always known I didn't think and experience the world like most other people. I just didnt know why or how. And it wasn't until just a few years ago I learned I had aphantasia, after my sister explained it. I didn't do much research into it then, and I'm 34 now, and have hit a wall in my marriage due to my mental health and this SDAM thing I have always dealt with. I didn't know it had a name, I didn't know theres all of you guys, here in this sub, also dealing with the same thing. and I am very excited to join and read your posts and learn how you all navigate the world with this knowledge.

Now that I have a name I can do more research, and gain more knowledge and learn how to communicate better with my family and friends, and even help my child as she seems to have the same way of experiencing the world. I know now that I have global/total aphantasia, affecting all senses. I live in a silent, imageless, purely conceptual internal world, where there is only my silent internal monologue. This has caused intense loneliness my entire life, and along with that the SDAM has caused me to not be able to recall conversations, events, people, etc. These two things have affected me greatly in every aspect of life, I have a hard time maintaining relationships of all kinds, I have troubles go to work consistently, I do not communicate with people well because I cannot remember events like they do, I get confused, irritated, and defensive, especially when I'm told something happened or I did something and I have either little or no memory of it, then in comes the confabulation. When my memory has failed me my brain defaults to making things up, creating a fictional narrative of what it thinks happened, and obviously this is usually false, and makes me into a compulsive liar regarding events that other people have extremely vivid visual memories of.

And now? I see my entire life from a different perspective, a new light. I have snippets of "memories" and conversations. I remember arguing with my sister as a child about what happened to our dolls and who's was whose, and now I understand that I was wrong.. I couldn't remember what happened to one of the dolls, I couldn't remember whose doll remained after one disappeared, I couldn't remember which one of us chopped their dolls hair off in weird chunks, because the dolls were identical before that. and we argued forever. and she was right the whole time because my memories were fabricated by my own brain since I couldn't recall actual events. I will apologize to her. I will also apologize to my husband.. For my inconsistencies, my apparent lies, my defensiveness, and all the hurt I've caused. Same with my mother, she has been there for me through it all, supported me mentally and financially, and always stood by me, always on my side, and never once questioned me or made me feel bad for being different.

Thanks for reading, I am going to go make a batch of cookies.

Struggling holding conversations

22 Upvotes

I have diagnosed AuDHD and have come to the conclusion after doing my own research that I likely experience SDAM as well. Out of all the memory disorders I've looked into SDAM seems closest to my experience, but every time i try to find tips to help with my conversational skills online or in therapy, it seems no one is directly addressing the specific problem I have. When i try to talk to people, i quickly run out of things to say. This usually takes me down two paths of research, one addressing autistic issues of misunderstanding social norms or conversational cues, the other addresses adhd or anxiety issues like missing details, not forming associations, or freezing. While i may struggle with these a little I don't think either of these are the dominant issue for me. My issue is my memory. I can sense social cues and know when im supposed to jump in, often times I know what i'm supposed to/ would like to talk about, just the information isn't there. I remember things in bullet points or general vibes, but never in enough detail to relay that information in an entertaining or practical way; that is, if I can remember at all. Often times I'm just left with nothing to say because i can't access my experiences in a meaningful way. This causes issues in every single relationship i have from family and friends to bosses and coworkers. To others i appear closed off at best. To myself I feel shame and guilt for being incompetent or uninteresting. This affects my core beliefs about myself and colors future interactions with a pessimistic undertone, which only reaffirms my negative beliefs about myself. I try to reframe and accept my shortcomings but at the end of the day i still struggle to communicate and i feel like it hinders my relationships and holds me back in life. No matter what I search, nobody's talking about my specific issue so i feel like i have to figure it out all on my own. It appears quick wit is my only defense against it, avoid having to talk about myself and divert with comedy. Everyone loves comedy right? But i don't remember any jokes, which creates pressure to always be coming up with something. This can cause me to zone out or miss details. I'm also in such a pessimistic mindset when talking to people that my jokes come off harsh or depressing or self deprecating which tends to create the opposite vibe of what i want out of these interactions. The only coping mechanisms I've found only end up activating those audhd responses, and making it harder for me to come up with anything to say at all. It's a compounding of many things, but I personally believe it stems back to issues with my memory at the root, and the engrained behaviors that developed as a side effect. If anybody knows where I can read more on this specific issue or have personal experiences that may be helpful to deal with this please comment or Dm me

TLDR: I struggle with communication because of what I believe to be SDAM, not Autism or ADHD, but none of the literature I've found actually focuses on SDAM. Do you have any advice or potential sources on how to deal with this?

A reminder for me

16 Upvotes

Saturday, I promoted to 5th degree blackbelt in Hapkido. It was part of an international seminar that had been announced in the works for a year. When it became clear that we would be using the presence of high-level people to do a bunch of upper-dan promotions, it was not clear to me that I would promote. Some others were obvious to me, but my promotion was not.

Afterwards, a couple of the leaders of my school told me about the decision to promote me. I was one of the first persons they knew deserved promotion. Evidently, many people had told them that my welcoming them to the school made the difference in them staying. And many commented on how important my work with them was to their progress. That same day, one of our 1st-degree blackbelts who had come for the promotions gave me a card expressing how important I had been to her.

What is the point to this? I continue to underestimate my impact on people.

Why am I posting it here? I won't say that SDAM causes this misperception, but I do think it sets it up for me. My base understanding of memory comes from personal experience which is SDAM. I don't expect people to remember the person who made them feel welcome. I am always pleasantly surprised when someone remembers me. I had met one of the event teachers at a previous seminar and done some practice with him. He is as far above me in skill (equivalent of a 9th degree blackbelt, although his system is different) as I am above a white belt. But he remembered me and warmly congratulated me on my promotion.

I figured this out 5 years ago when I learned about SDAM, but it seems I still underestimate my impact on people.

Which of these do you have? I have all twelve.

58 Upvotes

Which of these do you have? Tick all that apply.

  1. Visual aphantasia — no pictures

  2. Auditory aphantasia — no sounds in the mind

  3. Tactile aphantasia — no imagined touch or texture

  4. Gustatory aphantasia — no imagined taste

  5. Olfactory aphantasia — no imagined smell

  6. Kinesthetic aphantasia — no imagined movement or bodily sensation

  7. No inner voice — no inner speech, monologue, or narration of any kind

  8. Inaccessible autobiographical memory — facts but no re-entry into past events

  9. Automatic worded thinking, without sound — words arrive whole, silent, unconstructed

  10. No spatial imagery — can't build, rotate, or manipulate an object in the mind

  11. No scenario-building or forward projection — can't construct or simulate an imagined situation, whether about the future or anything else

  12. Out of sight, out of mind — no mental presence of absent people

I have all twelve. I'm trying to work out how rare that combination is.

A bit more detail. My autobiographical memory isn't just impaired, it's inaccessible. I know the facts of my life, but I can't re-enter any of it. I don't have an inner monologue or any kind of internal narration — no sound, no voice, no pictures, no sensory imagination of any kind.

I do feel real pain and real bodily states. I know when I'm hungry, when my throat is dry, when something hurts. What I can't do is generate those sensations in my mind when they aren't happening.

My thinking is worded, but it's automatic and silent. Words arrive whole, in the present, without prevarication or construction. There's no voice producing them, and I don't hear them. They're just there, as content.

I'd be interested to know whether anyone else has a similar profile, and how you experience memory, reading, and thinking. I've found that the standard descriptions don't quite fit, and I'm trying to work out what does.

María y pérdida de memoria

0 Upvotes

¿Soy al unico que cuando fuma/come galletas de maría recuerda toda su infancia? Aclaración de qué no consumo drogas, solo muy de vez en cuando y tengo algo más de 20 años.

Soy una persona que no recuerda nada de su infancia (salvo unos pocos recuerdos muy contados) creo que no tengo ningún trauma incluso algún familiar me ha dicho que he tenido una infancia súper buena con ningún trauma, suceso malo o cosas así.

Especialmente llevo un año que estoy perdiendo la memoria (olvido cosas básicas como los números de mi tarjeta, lo que hice exactamente ayer en el trabajo…) y en general no puedo retener información.

Cuando consumí galletas por primera vez, estaba jugando al Black Ops II (juego de mi infancia) con gente en mi cuarto y mientras jugaba a zombies estaba recordando toda mi infancia de forma lúcida y real en mi cabeza. Al día siguiente podía ver cosas y automáticamente se asociaban a cosas de mi pasado que creía olvidadas incluso mi pérdida de memoria desapareció por unos 3 días.

¿Alguien sabe cómo puedo usar esto a mi favor o recuperar mi memoria? Es urgente porque soy un zombie desde hace 1 año…

Muchas gracias, un abrazo!!

I have always been different. I've recently started a journey of trying to figure out what's wrong with me (it's a lot). My parents noticed at age 2-3 I was different. I had callous unemotional traits. I've never experienced empathy or been able to connect or attach to others normally. I've always been very self focused and only care about myself. I don't know if it was just how was born/genetics or if parenting also played a part but I seem to meet the criteria for being a psychopath. No real empathy,guilt,remorse. I'm not a terrible person because I was raised in a stable loving home where I learned how to mask and how to behave but I'm still by nature somewhat callous,selfish,unemotional, and self serving. I'm not not a sadistic evil serial killer and have never been violent a day in my life it feels mostly like an emotional handicap/deficit. I believe that it is a type of neurodivergence. I also have adhd.

One thing I have also learned about myself is that I have EXTREME aphantasia and SDAM. Which makes me curious if it's common for people with high psychopathic traits to have aphantasia/SDAM or vice versa. Just trying to learn more about my experience because it seems so complex and extremely rare.

When SDAM isn't SDAM

10 Upvotes

I wrote this for a dissociation sub, and thought about whether to also share it here. Asked the r/SDAM mods who told me to go ahead, so here it is. Likely irrelevant for most readers here, but possibly a little interesting anyway; and hopefully helpful for the few who, like myself, have a dissociative presentation resembling SDAM. I also wrote an earlier post about the science behind dissociation resembling SDAM if you're interested. And this post looks at the types of dissociation most likely to produce this presentation.

One important note: I was around 40 when I started experiencing episodic memories and visualisation in therapy, and I still only experience them rarely. Before that, I have no recollection of having these glimpses, though as I am generally unable to recall my internal experience, I can't say for sure that I never did. I only remember my internal experiences if they are accompanied by something external, e.g. talking to someone or writing them down in my journal.

Apologies for the length.

---

My conscious memories start at age 8, though I know there are earlier memories than that somewhere within me, beyond my conscious reach. With what level of detail, I don’t know. I have only seen glimpses in therapy sessions. Lots of emotional detail and some visual, but not much else so far; and the visuals I have seen to date have been more conceptual than rich in specific detail.

The memories I can recall consciously are probably broadly as detailed as anyone’s. By way of example, I remember being 8 and running from older kids at school into a school toilet and locking the door so they could not reach me; I think they wanted to exact revenge on me for something my older brother had done to them a year or two earlier. He was a bully, to his siblings and beyond.

I remember the school playground, the carpentry classroom (yes, we had one!) and how bad I was at carpentry. Never had the hand-eye coordination for anything. I remember one failed miniature ship in particular; I kept dripping paint all over it so often that I had to repaint it multiple times, ending up with a coat of paint so thick, it never dried properly. The final layer was a murky shade of green. I also made a small copper chandelier, with slightly better results.

I remember a reading competition in second grade (aged 8) which I won. It was a straightforward competition of who read the most books in X weeks at home. I was the kind of kid who didn’t do much apart from reading books, averaging at least a couple a week, including everything Enid Blyton ever wrote (and random encyclopaedias!). My prize was one more book: one about a knight, a princess, and a dragon. It had a black and white cover with some details in bright crimson.

I have thousands of memories like this, and I can generally place them on a timeline easily enough; definitely the right year, maybe close to the right month as well. Ish. From age 15 or so onwards, I would be able to confidently describe more or less every month of my life in reasonable detail, certainly on a level comparable to most people. If you knew me at some point in my past, ran into me and wanted to share stories, I would be able to trade blows as well as anyone.

However my conscious experience of my memories would be very different from what normal people have.

I don’t see my memories (aphantasia). I don’t hear them (anauralia). I don’t have an internal monologue describing them (anendophasia). I don’t feel them emotionally (not alexithymia!). I also don’t taste them, smell them, or experience any sense of touch or movement. I can run through any place I remember in my imagination using my spatial sense, but that also doesn’t come with any of the above.

Mostly, I just know the contents. I can use words to describe them like I just did, but my mind doesn’t autogenerate words internally. Words are reserved for communication with other people. I could paint and draw fairly crappy versions of what everything looked like, which is more down to a lack of drawing and painting skills than to any lack of memorised detail; my visual memory is well above average.

I recently compared my memory of a particular childhood place (my maternal grandparents’ farmhouse) with my younger sister. We remembered the details equally well, where everything was and who would be around, but where hers is a rich re-lived experience replete with cinematic visuals, rich sound, strong scents, distinct textures and so on, mine is “just knowing”.

She is there in her memory, feeling it in elaborate detail, which emotionally often means sadness and anxiety for her; we didn’t have a happy childhood, so painful memories outnumber happy ones.

I know my memories, but I don’t experience them. You wouldn’t be able to tell it if you talked to me about my memories, because words can only convey knowledge, and my knowledge covers every facet you can cover with words, including visual descriptions, even what kind of emotions people would exhibit.

But what did I feel in those memories? What was it like to be me, visiting my grandparents and them barely knowing who I was? “So you are so-and-so’s son, right?” Too many grandchildren to remember them all (around 200, I think; I don’t remember either). They likely knew more about their favourite chair than they knew about me, which is also true of my knowledge of most of my cousins.

Fundamentally, my own internal experience is not part of my conscious memories; it belongs to other mes.

When I have a glimpse of an episodic memory in therapy, that is the missing component most distinctly present. Yes, I see visuals, but they seem less central somehow; I’ve seen glimpses of my childhood living room before the walls were finished, so probably when I was 5 or 6. But in that memory, it was not what the living room looked like that felt central; the central feature was a powerfully ominous feeling, one of danger and threat, though the glimpse was too brief to tell what its source was.

A more recent and hence distinct glimpse in a similar vein happened last year when my son graduated high school. After the celebrations were over and I was alone in my room, I felt a crushing sense of defeat. Tears filled my eyes, and I started seeing image upon image of my son from when he was born and onwards: Crawling unhappily on a sandy beach (he was never into those); sleeping calmly against my chest in his baby sling; excitedly playing Minecraft on his first computer; jumping high with a wooden sword in his hand, enacting some fantasy play with his friends.

It felt like that was still him, that was still now, he was still just a baby, I was still trying to fix myself so I could be the dad he deserved.

But almost two decades had passed, I had failed to fix myself, and now he was all grown up; I had failed, and there was no fixing it. No going back, no returning to when rescue was still possible, no second chances. Time, as insubstantial as it felt, had beaten me.

That went on for a few hours, my shoulders shaking as I typed it all out, the pile of wet tissue on my desk growing ever taller.

I knew I would not be able to feel any of it when the moment was over, so I made sure to write it down for my son while I felt it. He did not get the dad he deserved, so the least I could give him was honesty: This is why I failed him, this is how terrible it made me feel, and this is how fervently I wished I could go back and steal him away from his mother, the Monster, when I still had the capacity to do so.

Later that evening, the feelings began to recede. I could feel them go the way you can sometimes feel a painkiller kick in after an injury. Soon enough I was back to my dissociated default self, which is not alexithymia but rather highly effective dynorphins and endocannabinoids produced by me, for me.

Unlike alexithymics, when my baseline dissociation recedes enough for me to consciously feel an emotion, I never have any trouble identifying, describing, and expressing it. (They tend not to come alone I should add; usually by the time I can feel them, there’s a whole lot of them in one complex bundle.)

I sometimes wonder if my memories consolidate after moments like that. Or do they live on inside me, just as painful as they were that day? Maybe it’s a mix. Seems like a whole lot of human things tend to be a mix, clear-cut B&W realities seem to mostly exist in our internal models. Maybe a little bit of consolidation and a little bit of retaining as-is. Or more like, as-was.

I am fairly agnostic when it comes to early memory glimpses in therapy; I’m not sure my childhood living room looked quite as yellow as it did in the glimpses I’ve seen, though my older brother says it did. Whether it did or didn’t isn’t really the point, I feel. Details are fairly ephemeral even for people with a normal autobiographical memory, and memory is fundamentally reconstructive in nature.

The feelings are likely real, as much as feelings ever are. I did likely feel lonely and abandoned a lot. That tracks both my current emotional self-experience, and what I know of my childhood; it wasn’t the sort of place where someone would care that you exist. It was the kind of place where a handshake was the height of intimacy, and life was mostly about hard work and waiting for heaven (so basically death, because that’s how you get there).

My sister once described it as a “nest of emotionally starved birdlings fighting over emotional scraps”. Unlike my older brothers, I was never much of a fighter, always more likely to shut down and quietly wait for my turn. “The only one of my nine babies to let me sleep properly”, as my mother once remarked. An excellent dissociator from birth, likely thanks to inheriting my mother’s dissociative base temperament, however that works; my brothers clearly failed to inherit it.

The feelings of anger I have connected with in therapy over the last half a decade or so have always been less about my mother as a person, and more about existential choices: Why have so many babies when you lack the emotional resources to provide for them? What kind of a god would send you to hell for only having five or six, and let you ascend to heaven once you’ve produced nine? What kind of a god would even insist on a causal relationship between where you ejaculate and the afterlife? As so often in life, the people who should be asking the most questions tend to ask the fewest.

When I do stream of consciousness journalling, it sometimes comes out like this:

“this is the recipe of life,”

said my mother

as she walked out of the room where i froze

“think of those flowers they plant

in the garden each year

they will teach you

that whatever grows

deserves life

and you

don't”

- Not Rupi Kaur

P.S.

If you'd like to rule out dissociation, you can start with these free, non-diagnostic screeners. They can only produce a rough estimate and are poorly adapted for people with aphantasia/SDAM, however a DES-II score of 30 or more, and/or a CDS score of 90 or more, would still be significanly higher than what SDAM alone would predict. Ultimately, a thorough assessment will require seeing a trained mental health professional for a structured interview.

SDAM Revelation

21 Upvotes

I recently learned about severely deficient autobiographical memory (I think in a post in the aphantasia sub) and was floored. I had no idea that people could have vivid memories of their experiences and see people and surroundings and remember what people were wearing, etc. That is completely alien to me.

When I talk about past experiences, it's a series of things that happened and maybe a quote by someone if it was funny or otherwise notable. For example, a few years ago I took my granddaughter and my niece to Itasca State Park not far from me in northern Minnesota. We went on the 10-mile paved Wilderness Trail Drive and parked a few times to go on trails. Then we went to the Mississippi River headwaters; we all walked on the bridge to cross, and the other two also crossed on the big rocks. Elsewhere, we saw what was formerly the Tallest Tree in Minnesota (it lost the top because of a lightning strike, I believe). My granddaughter, as usual, found some water critters. And we stood facing the cam and waved so family could see us later on YouTube.

None of that has much feeling to it, contrasting with my embarrassing moment at a girls' basketball game decades ago. I was the sports editor at my local newspaper and was covering a championship game. It was a close game, but the locals won. But the part I remember is a very simple thing: leaning against the wall during a time out and accidentally turning off the vapor lights. It was 10 minutes before they could resume because it takes time for the lights to be fully bright. I took my embarrassment into the school commons. Later, the coach would tell me he was glad for the extra time out because they were able to solidify the plans.

I remember that things happen, but I definitely do not vividly re-experience them or recall what things looked like. I wasn't that bothered to realize I had aphantasia, since I already knew I couldn't form pictures in my mind and my former husband could (but I didn't know it was a big deal). I was a little bummed when I read that people with aphantasia tend to have less vivid memories. I have always meant to keep a journal but rarely do so, and I forget so much.

When I learned not long afterward that I also do not have an internal monologue, it suddenly made sense that I'd seen comedy movies in which people could hear their own voices giving advice in their heads, or as in "All of Me," Steve Martin has Lily Tomlin residing in his head. It was very weird to realize that was actually a real thing that lots of people do.

But I was the most disappointed in the SDAM thing. For most of my adult life, I've been a newspaper reporter/editor, and I forget things from interviews later (I have often taken notes furiously and/or used a tape recorder). I often attribute my lack of memory to ADHD, which is probably true as well. When someone reads a board game's instructions out loud, it doesn't help me understand the game, because the words drift away.

I'm glad to have found this group. It has made some things make a lot more sense. Thank you.

SDAM and dreaming

4 Upvotes

How does everyone experience emotion in dreaming?

I have semi recurring dreams where I feel the emotion attached to certain people from childhood, a memory or nostalgia is experienced and I do actually feel those emotions during the dream, very intensely. Feels wild to me when I wake up because I don't experience anything like that in the waking world.

I assume this is a totally normal thing but I'm curious if people with SDAM experience this or something different?

storytelling vs. “making things up”

25 Upvotes

I recently found out that I have SDAM and global aphantasia, and someone posted recently about how others with SDAM deal with interviews, and everyone’s reactions / the comments unlocked something pretty big for me.

I’m realizing how much shame I’ve carried around the way I tell stories about my own life.

When someone asks me about something that happened in the past, even casually, I often don’t have an actual memory I can access and replay.

I do have pieces. Snippet here or there. Facts. Random fragments. Things I know happened. Things other people have told me. Or a picture that told me I was somewhere. etc

And somehow I’ve learned to take those pieces and string them together into a story that makes sense.

For a long time, I’d have this anxiety pop up almost immediately afterward: Did I just make that up? Was that really how it happened? Did I accidentally lie?

I’ve even felt like people close to me feeling suspicious of me when my recollection didn’t match theirs, and that has made me really self conscious. I think I’ve learned to retreat from having to tell stories about my personal life because of it.

Reading people here describe building a story from the scraps they do have was honestly such a relief. Like wait, other people do this too??

And maybe this is actually a skill I’ve developed because of how my memory works?

I’d love to hear how this works for other people with SDAM.

When someone asks you to tell a story from your past, what are you actually pulling from? Do you reconstruct it as you go, like me?

UPDATE: thanks for all of your responses! It’s nice to have a community here that reminds us when we are being too hard on ourselves!

Recently discovered total aphantasia and SDAM (20M) – Thoughts on Dune, fading memories, and feeling disconnected

11 Upvotes

First time posting on Reddit, so please bear with me!

Hi everyone, I’m a 20-year-old guy from Brazil and recently discovered I have total aphantasia and SDAM. I wanted to share a few thoughts and see if anyone relates to these experiences.

I first learned about aphantasia through a Brazilian podcast. The description matched my mind perfectly, and after looking into it, I realized I have total aphantasia. Digging deeper led me to SDAM. While there wasn't as much information available on SDAM, reflecting on my own life—and talking with friends—made everything click.

Aphantasia vs. SDAM

  • Aphantasia: Honestly doesn't bother me that much. It doesn't actively disrupt my daily life. The only time I really miss it is when reading books, as I’d love to visualize the scenes and characters, but that’s about it.
  • SDAM: On the other hand, this one genuinely frightens me. I have almost no memories of my childhood and very few from my teenage/school years. I also don't feel emotionally connected to my family in the way most people seem to be.

The "Cut Version" Feeling (The Dune Experience)

A clear example of how SDAM affects me happened just last week. I went to the cinema with friends to watch Dune 1 and 2—great movies. About four days later, I listened to a podcast breaking them down. As the hosts discussed various smaller scenes, I felt completely lost. It felt like they were talking about a cut version of the movie that I hadn't seen. I know I watched both films in full, but those details had already vanished from my mind.

Fading Memories and False Certainty

The most unsettling part right now is dealing with memories I can't verify:

  • When I try to recall what I did after an event (like going to the cinema years ago) or remember a specific scene, the factual details fade over weeks, months, or years.
  • My mind tries to fill in the blanks. I end up constructing a plausible story of what might have happened, repeating it to myself over time until I convince myself it's a real memory.
  • Because these are often solo experiences, I have no way to fact-check them with anyone else.

Does anyone else experience this feeling of watching a "cut version" of media, or the existential dread of not knowing if a memory was lived or just reconstructed? I’d love to hear your thoughts.

English is not my first language, so I used AI to help translate my thoughts and express how I feel

Interviewing - Tell me about a time when..

47 Upvotes

Going through interviewing now and this one is hard, even though I have 15 years of very relevant experience.

The only strategy that works for me is memorizing and drilling 5-10 anecdotes that cover the most common questions ahead of time. Even then, an unexpected question I don't have a ready answer for and I am sitting staring like a goldfish.
