The Doris Bither case, also known as the Entity hauntings, was an alleged haunting which occurred in 1974 at Culver City, California where a woman named Doris Bither alleged the ghosts of three Asian men were raping her. The case inspired Frank De Felitta's 1978 book The Entity which was made into a 1983 film of the same name starring Barbara Hershey.
