Yeah I have. Spiritual experiences, ghosts, aruas, talking to "god". I've done/expierienced it all. And then at one point I relieved and learned, no god, I'm just crazy. You don't need god to have a purpose in life, for it to be fufilling. A lot of times I feel like religion is for the hopeless/weak minded. Now don't get me wrong I don't think I am any better than you. I have more experiences I can not explain which I have had on psychedelics. Your life is pointless. You live for experience, and when you die you become part of the higher chain of life. That is the true meaning of life, it is the infinite cirlce of life.
