In the late 1970s, a quiet suburban home in Enfield, London, belonging to the Hodgson family got a new roommate – a poltergeist. The entity seemed to latch on to their 11-year-old daughter Janet who experienced levitation, violent attacks and had strange voices speak through her. The case was heavily investigated by paranormal researchers who agree an evil spirit was present, but some think there’s another explanation – regarding Janet’s supernatural abilities.
