Doris Bither case

The Doris Bither case, also known as the Entity haunting, was a 1974 investigation into alleged paranormal phenomena in Culver City, California, experienced by a woman named Doris Bither, who claimed to have been tormented and sexually assaulted by a supernatural entity in her home. Bither's alleged experiences were investigated by a team of researchers led by Barry Taff from the now-defunct parapsychology department from the University of California, Los Angeles. During the course of their ten-week investigation, numerous investigators claimed to have observed various supernatural occurrences in the home, including poltergeist activity and the manifestation of strange light figures which appeared throughout the house.

The case inspired Frank De Felitta's 1978 book The Entity, which was made into a 1982 film of the same name starring Barbara Hershey.
