James Wan’s The Conjuring 2, in theaters now, tells the infamous “Enfield Poltergeist,” which took place at a council house in Brimsdown village, borough of Enfield, England during the late 1970s.

Here’s what Wiki has to say:

In August 1977, single parent Peggy Hodgson called police to her rented home in Enfield after two of her four children claimed that furniture was moving and knocking sounds were heard on walls. The children included Margaret, age 13, Janet, age 11, Johnny, age 10 and Billy, age 7. A female police constable saw a chair slide on the floor but couldn’t determine if it moved by itself or was pushed by someone. Later claims included allegedly demonic voices, loud noises, thrown rocks and toys, overturned chairs and levitation of children. Reports of further incidents in the house attracted considerable press attention and the story was covered in British newspapers such as the Daily Mail and Daily Mirror, until reports came to an end in 1979. On Halloween 2011, BBC News featured comments from a radio interview with photographer Graham Morris, who claimed that a considerable portion of the events were genuine

The site also alleges that, American paranormal investigator Ed Warren claimed that Janet was once “sound asleep, levitating in midair” (pictured) and concluded that the children were the subject of demonic possession.

In this new featurette, the original family, as well as Lorraine Warren recount the events that inspired The Conjuring 2. It’s a shame this is only a few minutes long as I would love to see a full 30-minute documentary on one of the best documented hauntings in history.
