I did them several times in high school. Most of the time I just ended up in a very giggly, stoned feeling state. A few times I got completely messed up (in a good way). No life changing ensights, but nonestop laughter (to the point where your abdominals hurt from laughing, but you still can't stop, and then laugh even harder that you want to stop laughing but can't, and so on...).<p>Some random good memories, from various times:<p>- trees looked like they were breathing and I was sheltered under one from the snow and felt like I was communicating with it.<p>- my friends older brother had a goatee and was talking to us and he appeared to be a wise goat-human hybrid giving us advice, which sent me into a laughing fit.<p>- a really fat lady janitor at the movie theater reminded me so much of jaba the hut, it was so funny.<p>- it was snowing and my friends and me went tobagganning at night, I had all my snow gear on and felt like I was on another planet (too much fun to describe).<p>- Watching Vanilla Sky, it seemed like the craziest movie ever (have not since seen it sober - seemed absolutely magical in the theatre).<p>The only negatives were essentially being a little socially timid. I remember me and my friends did them at someone's house whose parents were away in the afternoon. They were throwing a party that night and I was pretty terrified at first when strange people began to pour into the house. My throat and mouth also felt sort of wierd - not neccesarily bad, but almost like there was a vacuum inside my stomach.<p>But most of the time, shrooms just weren't that intense. I think LSD is reputed to do more of what you describe. I hadn't thought about shrooms in ages, but I wouldn't mind doing them again. However, not being sure what your getting from a dealer is a deal breaker for me. I do not want to risk damaging my mind/body because some dealer added god-knows-what to the shrooms.
