Acid didn’t do this to me, and I’ve done a bunch… but everyone has a different experience.
I’ve been in a fair few K-Holes though, and one single experience where lines were laid out for a hotel room of myself and closest friends… it felt like too much powder to fit in my nose, but I did it anyway. By the time I laid down on one of the beds, my body?mind?spirit? Was being pulled downwards faster and faster, more quickly than any K-Hole I had ever experience. I have no way to explain the next hour; it would have been the most horrifying thing I could ever experience but I lost all concept of what horror could feel like. Time was visible and invisible and nonexistent. I knew in my brain that this wouldn’t be happening to me forever, but forever didn’t mean anything. I could look around and see all of my friends, but friends didn’t exist and I didn’t exist. I could move around but there was no point—physical reality wasn’t real anymore.
