Dude, I know what your talking about. I used to take alot of shrooms. One day we took like a 1/4 each and went for a hike in the bush. Everything was good, we tripped on the trees and shit blowing in the wind. A few months later, I had stopped taking shrooms due to a few too many bad trips, and I'm hiking in the bush looking for somewhere to grow and I start tripping on the trees again. It was the weirdest feeling. No stoney giggles, no butterfly's, just visuals. Since I haven't done any shrooms in a few years now it hasn't happened for a while. But I know what you speak of, though I was never able to put a name to it before. One question, did you every get that funny feeling in your stomach, like you where starting to get high and its there til you snap out of it? Just curious.
