I woke up today feeling incredibly anxious, paranoid, and just had a terrible gut feeling. The park near me is a massive trigger, but I wanted to face my fears and overcome it, so I decided to skip first period to go sit on the swings.
Mind you, the swings are exactly where I had a massive, traumatic "green out" a few months ago. As soon as I got there, the memory triggered my body completely. Suddenly, my depth perception broke: the swings and the floor looked tiny, miniature, and way closer to me than they actually were. Then, my vision literally turned into a 2D Roblox game. I am not exaggerating or using a metaphor—the textures on the floor literally flattened into blocky, rigid Lego/Roblox grids.
My soul felt like it left my body, and it felt like I was trapped in a completely different reality. As I tried to walk, my vision started lagging and freezing, like my eyes couldn't capture my movements in real time. It looked exactly like a choppy, flat, AI-generated video or a first-person video game.
This extreme visual shift only lasted for a few seconds, but it felt awful and terrifying. About an hour later, it spiraled into a massive panic attack. I've had other incidents lately where things turn small, my vision feels like I'm completely on drugs, and I go entirely out of body. The closest way I can describe it to anyone is that it feels exactly like I'm greening out all over again, even though I am completely sober.
Has anyone else experienced literal, geometric, and blocky visual transformations during severe panic attacks or DPDR? I feel so lost and terrified that my brain is stuck like this.
