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.
