The Rosenheim Poltergeist, Bavaria (1967)

The Rosenheim poltergeist (1967–68) is among parapsychology's most-investigated cases: disturbances in a Bavarian law office — swinging lamps, electrical surges and unexplained phone records — were studied by Hans Bender (IGPP) and physicists, who linked them to employee Annemarie Schaberl. Sceptics proposed wiring faults and manipulation; the case remains unresolved. Recorded by PRN as a documented investigation — historical context, not proof.
