Stone Tape theory

The Stone Tape theory is a pseudoscientific claim that ghosts and hauntings occur when traumatic events are imprinted on certain stones or other materials and are subsequently replayed, similar to a magnetic tape recording. The idea of materials holding information from emotional events aligns with views of 19th-century intellectuals and psychic researchers, such as Charles Babbage, Eleanor Sidgwick and Edmund Gurney.

Contemporarily, the concept was popularised by Nigel Kneale's 1972 horror-drama television play The Stone Tape.
