poltergeist

This term describes a specific type of paranormal entity characterized by kinetic energy rather than mere visual apparitions. While a ghost is often perceived as a lingering soul or a silent observer, a poltergeist is defined by its disruptive, noisy, and physical interactions with the material world.

In modern usage, the word often carries a tone of chaotic unpredictability. It is frequently employed in horror cinema and folklore to evoke a sense of domestic instability, where the safety of the home is violated by invisible, aggressive forces.
