Poltergeists

The most famous "English Poltergeist" is The Enfield Poltergeist.
The period of the poltergeist activity happened in England between August 1977 and September 1978, with an added outburst in August 1980

The said activity occurred at Enfield in North London, in a council house rented to Peggy Hodgson, a single parent with four children.

During this time furniture is said to have moved by itself, knockings on the walls were heard, and children's toys were said to have been thrown around and to have been too hot to touch when picked up. A police officer signed an affidavit to affirm that she saw a chair move. Reports of the activity attracted various visitors including mediums and members of the press. After visiting the house, George Fallows, a senior reporter for the Daily Mirror, suggested that the Society for Psychical Research (SPR) be called in to investigate.

The incidents were duly investigated by Maurice Grosse and Guy Lyon Playfair, both members of SPR, who were convinced by the evidence which they encountered during their thirteen month investigation. They reported witnessing various phenomena, including moving furniture, flying marbles, cold breezes, shallow pools of water appearing on the floor, and fires which spontaneously ignited and extinguished themselves.

The family in the Enfield case consisted of a mother, two daughters, and two sons; Margaret aged 12, a younger sister Janet aged 11, Johnny aged 10 and Billy aged 7. Billy had a speech impediment. Johnny featured only marginally in the inexplicable events, at least 26 of which the investigators considered could not be accounted for by fraud. These included movement of small and large objects, interference with bedclothes, pools of water on the floor, apparitions, physical assaults, graffiti, equipment malfunction and failure, spontaneous combustion, disappearance and reappearance of objects, and apparent levitations.

Among other alleged phenomena they witnessed was one of the children speaking using her false vocal folds for hours on end (which is believed to be medically impossible), while she was apparently possessed by another entity. When speaking with the false cords she said she was "Bill" who had died in the house. Recordings were made of these occurrences. After the BBC went to the house the recording crew found the metal inside of the recording machines bent, and recordings had been erased.
