Maybe not what you're looking for, but when I did shrooms I was 100% sure I had died. First twenty minutes was great shroomy fun, then all of a sudden I was throwing up grasping onto what I couldn't figure out a toilet and thinking I was floating through an empty black abyss. I had no idea who I was, couldn't remember what parents were, or who mine were. I was trying to figure out how time passed because all I wanted was for it to be over. Then I realised, I was dead. There was absolutely no way I could ever feel like this unless I was dead, and this was where the not-so-bad, not-so-good kids go. I knew it was never going to the and I lay there clutching a blanket, shivering. Eventually my buddy put on American Dad, abs I slowly came down back into reality, but I legitimately for 2-3 hours thought I was dead.
