I dont know but your comment made me think of the kentucky prophet.

Edgar Cayce-a psychic counselor and healer. Accepted nationally, he was one of the best known in this field. A humble and religious man, Cayce never profited from his predictions.

This guy would go into a sleep like state where he would diagnose people's health conditions while being tapped into whatever it was he claimed he was tapped into.

Alot of the times he would tell these people, go eat lemons, or eat a turnip. Random shit like this but supposedly he had a 100% cure rate.
