Cayce was a conman.. Do some research. He worked in a library and was an avid reader with a photographic memory. All he did was mumble in his sleep about whatever he'd read. When his friend wrote down what he said in his sleep cayce decided he was psychic and advertised readings in the paper to make some dollars. He never had any success as a psychic. No one had any of his predictions come true so he gave out nothing but medical advice that he got from books.. He got a following because some of his medical advice worked. He had zero success predicting the future.
