The poltergeist is a mysterious agency which manifests its presence by noises, knocking, etc. It is connected in some way with the unconscious of someone on the scene. The phenomena are supernormal but not supernatural. Little has been done to stop effectively or 'cure' such disturbances through medical or psychological therapy. While director of research of the International Institute for Psychical Research in London from 1934 to 1938, Fodor investigated and treated the case he reports. The poltergeist activities then ceased. He attributes the mysterious psychokinetic phenomena to unconscious projections due to psychic conflict in a schizoid personality. He fails to explain the continuation of the poltergeist activities while his patient was away in Paris. There is no hint as to the manner in which the unconscious can activate these phenomena from a distance.
