In German folklore and ghostlore, a poltergeist (/ˈpoʊltərˌɡaɪst/ or /ˈpɒltərˌɡaɪst/; German: [ˈpɔltɐɡaɪ̯st] ; 'rumbling ghost' or 'noisy spirit') is a type of ghost or spirit that is responsible for physical disturbances, such as loud noises and objects being moved or destroyed. Most claims or fictional descriptions of poltergeists show them as being capable of pinching, biting, hitting, and tripping people. They are also depicted as capable of the movement or levitation of objects such as furniture and cutlery, or noises such as knocking on doors. Foul smells are also associated with poltergeist occurrences, as well as spontaneous fires and different electrical issues such as flickering lights.[1]
These manifestations have been recorded in many cultures and countries, including Brazil, Australia, the United States, Japan and most European nations. The first recorded cases date back to the 1st century.
Skeptics explain poltergeists as juvenile tricksters fooling credulous adults.
