Paranormal.

The Enfield Poltergeist

Beginning August 30, 1977, the Hodgson family at 284 Green Street in Enfield, North London reported moving furniture, knocking noises, and disembodied voices that lasted roughly fourteen months. Two investigators from the Society for Psychical Research were present for most of it, recording about 1,500 incidents. A police constable signed a statement saying she saw a chair move on its own. Some events were later admitted to have been faked. Others were not.
