Artist conception of poltergeist activity claimed by Therese Selles, a 15-year-old domestic servant of the Todescini family at Cheragas, Algeria. From the French magazine La Vie Mysterieuse in 1911.

In folklore and parapsychology, a poltergeist is a type of ghost or other supernatural being supposedly responsible for physical disturbances such as loud noises and objects moved around or destroyed. Most accounts of poltergeists describe movement or levitation of objects, such as furniture and cutlery, or noises such as knocking on doors. Poltergeists have also been claimed to be capable of pinching, biting, hitting and tripping people.

Poltergeists occupy numerous niches in cultural folklore, and have traditionally been described as troublesome spirits who haunt a particular person instead of a specific location. Such alleged poltergeist manifestations have been reported in many cultures and countries including the United States, Japan,[1] Brazil, Australia, and most European nations, with early accounts dating back to the 1st century.[2]


The word poltergeist comes from the German words poltern ("to make sound") and Geist ("ghost" and "spirit"), and the term itself roughly translates as "noisy ghost" or "noise-ghost".



Many claimed poltergeist events have proved on investigation to be pranks.[3] Skeptic Joe Nickell says that claimed poltergeist incidents typically originate from "an individual who is motivated to cause mischief".[4] According to Nickell:

"In the typical poltergeist outbreak, small objects are hurled through the air by unseen forces, furniture is overturned, or other disturbances occur -- usually just what could be accomplished by a juvenile trickster determined to plague credulous adults."

Nickell writes that reports are often exaggerated by credulous witnesses.[5]

"Time and again in other “poltergeist” outbreaks, witnesses have re­ported an object leaping from its resting place supposedly on its own, when it is likely that the perpetrator had secretly ob­tained the object sometime earlier and waited for an opportunity to fling it, even from outside the room—thus supposedly proving he or she was innocent."

According to research in anomalistic psychology claims of poltergeist activity can be explained by psychological factors such as illusion, memory lapses and wishful thinking.[6] A study (Lange and Houran, 1998) wrote that poltergeist experiences are delusions "resulting from the affective and cognitive dynamics of percipients' interpretation of ambiguous stimuli".[7]

Attempts have also been made to explain scientifically poltergeist disturbances that have not been traced to fraud or psychological factors. David Turner, a retired physical chemist, suggested that ball lightning could cause inanimate objects to move erratically.[8] Michael Persinger has theorized that seismic activity could cause poltergeist phenomena.[9] Milbourne Christopher found that some cases of poltergeist activity could be attributed to unusual air currents, such as a 1957 case on Cape Cod where downdrafts from an uncovered chimney became strong enough to blow a mirror off of a wall, overturn chairs and knock things off shelves.[10]


Parapsychologists such as Nandor Fodor and William Roll wrote that poltergeist activity can be explained by psychokinesis.[11][12]

Poltergeist activity has often been believed to be the work of malicious spirits. According to Allan Kardec, the founder of Spiritism, poltergeists are manifestations of disembodied spirits of low level, belonging to the sixth class of the third order. They are believed to be closely associated with the elements (fire, air, water, earth).[13]

Physicists Pierro Brovetto and Vera Maxia hypothesise that poltergeist have for origin a reduction in strength of molecular bonds due to an enhancement in polarization of vacuum which decreases the actual electron charge. Arguments based on Prigogine' nonequilibrium thermodynamics are proposed, which show how transformations in brain of some pubescent children or young women might be the cause of these effects.[14]
