I am still in shock after having what could best be described as an "episode" earlier this evening. We were sharing two bowls between three of us, so we weren't smoking a huge amount, when all of a sudden I lost all connection with the outside world, and started thinking that we were walking home when in all reality we were standing still and then completely collapsed! I then tried to stand up, immeditately once again lost all touch with reality and collapsed again!!! I then stayed still until in an instant I has 100% coherent again and only a little bit stoned like usual... as if the whole thing hadn't happened.
I have been smoking quite a bit of weed for quite a few years, and have never been one to even get sketched out and now I'm both terrified and a little bit embarrassed... have any of you ever heard of this happening due to weed? Or maybe the weed had nothing to do with it at all... maybe it would have happened regardless? Any/all feedback would be hugely appreciated because this has freaked me out!!!
