When I was in high school, I was smoking weed in a car with some people, and we passed a 7-Eleven. I had an epiphany of sorts, and told everyone that I finally figured out why it was called 7-Eleven, and that was because 7+11=24 as in 24 hours. Everyone was like "Yeah, that's right!". It was really stupid.
A friend of mine was driving his car once and we were really out of it, and I hear this weird ticking noise. I turn and see him trying to start the engine while it is already running (we are moving full speed when this happens)! It was pretty funny, but pretty scary, we had to pull over for awhile or else get into a mess on the road.
I also answered my phone when my dad was calling, due to severe tunnel vision I couldn't see who it was, and I was rolling on 2 double stacked pills and sounded like I was having sex. It was weird.
I also was really fucked on Stilnox once, and cut one class. I was peering in the door, for some reason I thought it was a one-way pane. My teacher was staring at me, looking quite angry. I went inside and sat on the floor (the aisle). Of course, I don't remember THAT part.
I also cut class another time (on much downers again) and went to ask my classmates what had happened. I sat out in the corridor to wait for class to end, and eventually fell asleep all sprawled on the floor, only to be nudged by a shoe (someone thought I was dead).
I have tons of stories, from my more heady days past. This can do serious damage to your liver. I cannot advise against it enough, especially copious amoutns of everything.
