Old saying, I think maybe Confucious?
Last night I dreamed I was a butterfly, and today, I do not know if I am a human being who dreamed of being a butterfly, or a butterfly dreaming that I am a human being.
The Hindu's believe that what we like to call reality is their god, Vishnu's dream.
Joe, if you haven't read it already, try Illusions:The Adventures of a reluctant Messiah, by Richard Bach. It's a fun story and a quick read, and can give you a whole new perspective on reality and dreams.
