In August 1949, ‘The Washington Post’ran at least two stories about a 14-year-old boy’s exorcism in Maryland. In one, the newspaper reported, “The boy broke into a violent tantrum of screaming, cursing and voicing of Latin phrases—a language he had never studied.” The story inspired author William Peter Blatty’s 1971 novel ‘The Exorcist’, the basis for the 1973 film in which a young Linda Blair projectile-vomits pea soup.

A decade after Amityville, Ed, and Lorraine Warren again became involved with the Snedeker family. Allen and Carmen Snedeker claimed they’d experienced paranormal phenomena at the Connecticut house they rented in 1986. The Warrens hired novelist Ray Garton to record their experiences and published a book called ‘In a Dark Place: The Story of a True Haunting’ in 1992. In 2009, a movie inspired by the Snedeker case called ‘The Haunting in Connecticut’came out.

‘A Nightmare on Elm Street’is based on a totally real — albeit rare — medical condition that leads to mysterious deaths. The victims would scream in their sleep only to be found dead the next morning, resulting in this phenomenon called ‘nightmare deaths’. Research proves that the afflicted were in perfect health before their sudden demise which makes all of this even more scary and inexplicable.

Ed and Lorraine Warren were involved in so many hauntings during their decades-long careers which inspired the Conjuring saga! The first ‘Conjuring’ movie is about the Perron family, who claimed in the early 1970s that spirits were haunting their Rhode Island house. The film also references a previous Warren case about a supposedly haunted doll, which inspired the spin-off Annabelle saga and more further.
