Arguably one of the eeriest movies in recent memory, The Conjuring is inspired by the real-life experiences of private investigators Ed and Lorraine Warren as they investigated the Perrons, a family that moved into a farmhouse and experienced paranormal hauntings in 1979.

According to the people working on the movie set, the filming process was rife with supernatural events. Cast and crew members reported feeling strange winds that would blow around particular people, but not trees. The director also reported noticing that one night, his dog appeared to be barking at something invisible and following it with his eyes.
