Not exactly the same, but I’ve experienced derealization in other ways..It happens about surroundings for me. Once, when we were driving on a highway, the buildings and road and the sky started looking like they were made of thin paper. I felt like I was stuck inside one of those pop-up books for children, where there’s entire landscape made of paper.

It made me extremely nauseous and disgusted with existence. I started thinking about liminal spaces theory later. Like being stuck in the backrooms when you try to no-clip out of this reality. This kind of derealization happens for me only when I’m around liminal spaces (corporate buildings, gas stations, etc).
