Speaking of antics after getting high...
I spent the past summer in Ithaca. One day, me and my friends Carlos and Andrea (my girlfriend at the time) got really bored and decided to eat some shrooms. Now, we had done this before but we were REALLY bored so we doubled the dosage this time. The stuff kicks in pretty quickly, and we want to take a walk outside to really experience it. Eventually, we walk down into a gorge (for those of you unfamiliar with Ithaca, it's full of gorges). We spend a while down in the gorge just looking up at the sky. If I remember correctly, there was a rainbow that really freaked us out. At this point, Carlos suggests that we fall asleep because you have really trippy dreams when you're on psilocybin. So we all lie down in the gorge. After a while, I wake up (still a little high but quite lucid) and the two of them aren't around anymore. First I'm mad because I thought they ditched me, then I start to panic, thinking they might have jumped into the river in the gorge. So I go walking downhill along the gorge, and eventually I find them sitting on a rock, just talking.
Apparently, what happened is that they couldn't fall asleep and Andrea thought that she had seen a something in the river, and for whatever reason they decided it must have been a dolphin...so they both spent the next couple of hours "chasing after the dolphin in the gorge".
