We all know the famous ghost hunting couple Ed and Lorraine Warren and the films Conjuring 1 and 2 that were based on their real life experiences. But do we know that the following films were an addition to their list? Read on to know which ghost stories really existed in the couple’s case files.

According to the Warrens, in 1970, two roommates claimed their Raggedy Ann doll was possessed by the spirit of a young girl named Annabelle Higgins. The Warrens took the doll, telling the roommates it was "being manipulated by an inhuman presence", and put it on display at the family's "Occult Museum". The 2014 film Annabelle directed by John R. Leonetti is loosely based on the story.

The Warrens' first claim to fame was their involvement in the 1976 Amityville Horror case in which New York couple George and Kathy Lutz claimed that their house was haunted by a violent, demonic presence so intense that it eventually drove them out of their home. The Amityville Horror Conspiracy authors Stephen and Roxanne Kaplan characterized the case as a "hoax". Lorraine Warren told a reporter that the Amityville Horror was not a hoax. The reported haunting was the basis for the 1977 book The Amityville Horror and the 1979 and 2005 movies of the same name.

Pennsylvania residents Jack and Janet Smurl reported their home was disturbed by numerous supernatural phenomena, including sounds, smells and apparitions. The Warrens became involved and claimed that the Smurl home was occupied by three minor spirits and also a demon that allegedly sexually assaulted Jack and Janet Smurl. The Smurls' version of their story was the subject of a 1986 paperback titled The Haunted and a 1991 made-for-TV movie of the same name directed by Robert Mandel.

In 1986, Ed and Lorraine Warren arrived and proclaimed the Snedeker house, a former funeral home, to be infested with demons. The case was featured in the 1992 book In a Dark Place: The Story of a True Haunting. A TV movie that later became part of the Discovery Channel series A Haunting was produced in 2002 and a film very loosely based on the events, directed by Peter Cornwell, was released in 2009.

'Ed Warren's book Graveyard: True Hauntings from an Old New England Cemetery (St Martins Press, 1992) features a "White Lady" ghost which haunts Union Cemetery. He claimed to have captured her essence on the film Union Cemetery.

Believe in ghosts or not, this couple has inspired a lot of creative minds and has helped them nail the box office collections many a times with their haunting experiences.
