I had about a level 4 trip and it was not fun. I did not trust many people and/or things around me. I was in a different world...almost schizo like... It is hard for me to explain, but if you watch Donny Darko it somewhat explains what i was feeling. Being in my own world and coming and going back in and out of reality. Thinking i was in reality in my mind when really i was not at all in reality.
