As someone described above about a "near death" trip, I had one too..I was convinced I had overdosed even though I was positive it was impossible. When you're that fucked up, there is no logic. I sat there for hours thinking I was going to implode, my whole body was vibrating, I saw "the light", and actually waited in Pergatory. I was seriously considering calling my parents and letting them know that their son was about to overdose on drugs, for fortunately, I couldn't figure out how to use my phone. I had various revelations about death, what happens after death, and the whole experience. I couldn't understand the concept of being buried, and thought that my body would merely disintigrate after death. To some degree, I think I actually talked to God and he said it'd be cool if I went to heaven, because at the time, I was obviously suffering in hell. I ended up waking up in my friends car at three in the morning with no recollection of where I was at all. I tried starting the car with my finger for over and hour and couldnt figure out why I was so fucking cold, granted it was the middle of January and I was inside a car parked outside. If I had known my friend had I knife in the center console, I most surely woudl've killed myself just to end it..However, I've tripped so many other times and had an absolute blast, I don't know what causes such a horrible trip. On a related note, I'm fairly small, maybe pusing 5'5". The amount of food poisoning that 4 or 5 grams of shrooms has given me is unbearable, just terrible feelings throughout my whole body, and I think that might lead to the bad trips. I've been looking into brewing tea in hopes that the wierd anxious, tossy/turny feelings wouldn't come with the trip. In my opinion, if you're going to do shrooms, as much as it might seem more "hardcore", the trips are incredibly similar, almost to the point where you could equate one hit to a gram with a certain amount of accuracy. If you're planning on tripping, don't be with kids who might fuck with you, it's always good to have a spotter, day is better than night (just don't be out in the open where people might call you out, or where you'll get paranoid about that happening), and music becomes your own personal concert..Bring an ipod!
