tripping is like a bunch of mini hiatus condensed all together. you take a break from reality, live and explore, and then you come back and tell your mind where you've been.
i should of said take a break from your reality, or own local physical reality, or something like that. either way your mind wanders off and come back again, over and over again, each time coming back with a new experience under your belt and a new perspective on life.
Acid lets your mind break away from reality. Reality is created by your mind and lsd helps you become a non-thinking being.
