A poltergeist is a type of supernatural entity often associated with physical disturbances, such as loud noises, moving objects, and other unexplained phenomena. The term comes from the German words "poltern," meaning to make noise, and "geist," meaning spirit. Unlike traditional ghosts, which are often thought to be the spirits of deceased individuals, poltergeists are believed to be manifestations of energy, sometimes linked to a living person, particularly adolescents. Reports of poltergeist activity have been documented throughout history and across cultures. These occurrences can range from harmless pranks to more intense disturbances, causing fear and confusion among those experiencing them. While some attribute these events to paranormal forces, others suggest psychological explanations, such as stress or repressed emotions, particularly in relation to the individual involved.
