Poltergeist

Poltergeist(German for noisy ghost) is a term used to describe a supposed spirit or ghost that manifests itself by moving and influencing inanimate objects.

Reports of poltergeist activity typically feature raps, bumps, thumps, knocks, footsteps, and bed shaking, all without a discernible point of origin or physical reason for occurrence. Many accounts also report objects being thrown about the room, furniture being moved, and even people being levitated.
