Poltergeist-type occurrences were reported in a private residence in Florida from November 1996 to January 1997. In addition to movement of objects and other typical RSPK manifestations, unexplained appearance of water was described. The family believed the house to be "haunted." Several techniques were employed to investigate the phenomena. The premises were tested with a magnetometer and non-contact thermometer. The location was photographed and psychological examinations were administered to three primary witnesses. Correlations between geomagnetic/electromagnetic activity and the alleged paranormal events were studied. Psychological tests indicated that one of the witnesses conformed to the profile of a "poltergeist personality," an adolescent with a low tolerance for frustration, repressing feelings of aggression and hostility. Neuropsychological questionnaires suggested temporal lobe lability in two of the witnesses, including the apparent poltergeist agent. Magnetic field strengths at several locations where unexplained phenomena had been reported differed significantly from magnetic field strengths in locations where no unusual phenomena had been reported.
