One time I took too many Tylenol-3 and felt really awesome for about an hour, then for the next five I was paranoid as hell. I had to walk through a busy lunch room and I was sort of leaning away from everyone at once and just staring terrified at them.

Nothing really sketchy has happened to me when I'm high though. I had some lady ask me if my dog had pooped on her yard, but I had already picked it up so she apologized for being mad at me. That's about it.
