In folklore and parapsychology, a poltergeist (German for "pounding ghost") is a type of ghost or other supernatural entity which is responsible for physical disturbances, such as loud noises and objects being moved or destroyed. They are purportedly capable of pinching, biting, hitting, and tripping people. Most accounts of poltergeists describe the movement or levitation of objects such as furniture and cutlery, or noises such as knocking on doors.
