Edgar Cayce was an American psychic who was famous during the early 20th century. He was notorious for giving readings during an alleged trance state he entered while sleeping. There’s a foundation that stores the readings that were recorded later in his “career” and they have been a topic of debate among his followers and skeptics.
During the documentary; "Edgar Cayce - An American Prophet", on New Heaven, and Barnes & Noble, it is mentioned that among his visitors were some important figures of the era like Nelson Rockefeller.
Is there any truth in these claims?
