In paranormal studies, a poltergeist phenomenon alludes to the apparent yet unexplained manifestation of multiple force reactions caused by a seemingly invisible entity. Most accounts of poltergeist manifestations involve such force being triggered at objects, usually household (destruction and relocation of furniture, levitation of cutlery, knocking on the doors), although some seem to describe accompanying hallucinations, as well as physical attacks on human witnesses. Such actions can include pinching, biting, hitting and tripping the victim, or producing sentient noises (moaning, laughing, talking etc.) without clear source.
Poltergeists occupy numerous niches in cultural folklore, and have traditionally been described as troublesome spirits who, unlike ghosts, 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, Brazil, Australia, and most European nations. The earliest recorded cases date back to the 1st century.
Most reports of poltergeist manifestations involve noises and destruction that have no immediate or verifiable cause. Situations include inanimate objects being picked up and thrown; noises such as knocking, rapping, or even human voices; and physical attacks on human beings, such as pinching, biting, and hitting.
Single poltergeist cases often range in duration from a few hours to several months.
Many claimed poltergeist events have proved on investigation to be pranks.
According to research in anomalistic psychology claims of poltergeist activity can be explained by psychological factors such as illusion, memory lapses and wishful thinking. 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".
Attempts have also been made to explain scientifically poltergeist disturbances that have not been traced to fraud or psychological factors. The psychical investigator Guy William Lambert proposed a geophysical explanation for poltergeist activity which results from the activity of underground water and other factors. According to Lambert many reported poltergeist incidents can be accounted for by physical causes such as "subterranean rivers, tidal patterns, geological factors and shifts in the house foundation, and climate changes." His theory was that an underground water course may flow under "haunted" locations and that after heavy rainfall the stream could cause structural movement of the property, possibly causing the house to vibrate and move objects.
Michael Persinger has theorized that seismic activity could cause poltergeist phenomena. Persinger's case studies have also shown a complex interaction between geomagnetism, household electrical equipment and the brain physiology of the individual.
Skeptics such as Milbourne Christopher have found that some cases of poltergeist activity can 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.
Other investigators have postulated that psychopathology or aggression in the subjects themselves may be responsible for the action of movement of objects in poltergeist cases. Nandor Fodor proposed that poltergeist disturbances are caused by human agents suffering from some form of emotional stress or tension and compared reports of poltergeist activity to hysterical conversion symptoms resulting from emotional tension of the subject. Owen (1978) cited a number of poltergeist cases in which the subject displayed signs of hysteria.
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).
Famous poltergeist cases 
Lithobolia (1698) 
Lithobolia, or the Stone-Throwing Devil, is a pamphlet that records poltergeist activity that allegedly took place in the tavern of George and Alice Walton in 1682. Two copies of the pamphlet exist in the British Museum. The Waltons' tavern was located in New Castle, New Hampshire, then known as the Great Island. Lithobolia was written by “R.C.,” one Richard Chamberlain, the secretary of the colony of New Hampshire. In 1666 Chamberlain was boarding at the Walton tavern and witnessed the attack. The pamphlet was later printed in London by Chamberlain in 1698. The opening reads:
"Lithobolia", or stone throwing Devil. Being an Exact and True account (by way of Journal) of the various actions of infernal Spirits or (Devils Incarnate) Witches or both: and the great Disturbance and Amazement they gave to George Walton's family at a place called Great Island in the county of New Hampshire in New England, chiefly in throwing about (by an Invisible hand) Stones, Bricks, and Brick-Bats of all sizes, with several other things, as Hammers, Mauls, Iron-Crows, Spits, and other Utensils, as came into their Hellish minds, and this for space of a quarter of a year."
Borley Rectory (1937) 
William Roll, Hans Bender, and Harry Price are perhaps three of the most famous poltergeist investigators in the annals of parapsychology. Harry Price investigated Borley Rectory which is often called "the most haunted house in England."
Rosenheim, Germany (1967) 
Dr. Friedbert Karger was one of two physicists from the Max Planck Institute who helped to investigate perhaps the most validated poltergeist case in recorded history. Annemarie Schneider, a 19-year-old secretary in a law firm in Rosenheim (a town in southern Germany) was seemingly the unwitting cause of much chaos and controversy in the firm, including disruption of electricity and telephone lines, the rotation of a picture, swinging lamps which were captured on video (which was one of the first times any poltergeist activity has been captured on film), and strange sounds that sounded electrical in origin were recorded. Karger stated that "these experiments were really a challenge to physics" and the disturbances "could be 100 percent shown not to be explainable by known physics." Fraud was not proven despite intensive investigation by the physicists, journalists and the police. The effects moved with the young woman when she changed jobs until they finally faded out, disappeared, and never recurred.

- The family observed pots and pans being thrown around the kitchen, blinds moving up and down, lights going on and off, doors locking themselves, chairs flying across the room, and cupboard doors opening and banging shut before being ripped off their hinges among other phenomena.
- The strange occurrences started a couple of weeks after Manning and her children moved into the Coventry council house.

- Renowned medium, Derek Acorah visited Manning's home, stating that he was able to communicate with the spirit, and that it was called "Jim" and had died from a heart attack at the age of 58 around 1900. Acorah then performed an exorcism ceremony, after which the paranormal activity ceased.

Evidence of water damage could be seen on the floor space that the bed originally occupied. There have been no further incidences reported at this address.
