I think most people who use psychedelics more than just an occasionally will eventually have some very strange ideas, messianic complex, have I died and gone to hell, are all my friends plotting to kill me, is any of this even real? Some of these ideas will hang aound, coming back trip after trip. The secret to life? Letting go, its ok to lose our minds sometimes but we need to be able to say, last night was crazy, nice to be back, not WOW this is the absolute truth! When we believe our own ideas whole heartedly we know we cant be completely correct, this is why it is best to dabble in beliefs have ideas, because there will allways be a new truth around the corner coming to crush our old truth.
