Edgar Cayce (1877-1945) has been called the sleeping prophet, the “father of holistic medicine,” and the most documented psychic of the 20th century. For more than 40 years of his adult life, Cayce gave psychic “readings” to thousands of seekers while in an unconscious state, diagnosing illnesses and revealing lives lived in the past and prophecies yet to come. But who, exactly, was Edgar Cayce? This documentary tries to answer this question.
