I've tripped on mushrooms twice now and both times I felt this overwhelming sense of deja vu towards the end of the trip. I was wondering if other people had the same experience.
It's almost as if you've done everything that you're experiencing before...either in early childhood, in your dreams, when you were really really sick, or maybe in a past life. I had thoughts that perhaps my life was circular, that it repeats over and over.
Needless to say I badtripped the second half of my first time and the second time. I eventually came to the conclusion through introspection that somehow the mushrooms were working on a area of my brain related to memory and is somehow just messing with it. Anyway noone else that I tripped with experienced these feelings, and it gave me a frightening feeling that perhaps nobody really understands, that I am the only one that is TRULY alive. Basically feelings of solipsism.
Tip to anyone tripping for the first time: DON'T ISOLATE YOURSELF!! THIS IS AN EXTREMELY BAD IDEA!!!
Anyway, even if you do have a bad trip, hopefully you can gain some greater insight into your life as I have.
