haunted

A haunted house, spook house or ghost house in ghostlore is a house or other building often perceived as being inhabited by disembodied spirits of the deceased who may have been former residents or were otherwise connected with the property. Parapsychologists often attribute haunting to the spirits of the dead who have suffered from violent or tragic events in the building's past such as murder, accidental death, or suicide.
In a majority of cases, upon scientific investigation, alternative causes to supernatural phenomenon are found to be at fault, such as hoaxes, environmental effects, hallucinations or confirmation biases. Common symptoms of hauntings, like cold spots and creaking or knocking sounds, can be found in most homes regardless of suspected paranormal presences. People are more likely to experience a haunting when they are about to fall asleep, when waking, or if they are intoxicated or sleep-deprived. Carbon monoxide poisoning has been cited as a cause of suspected hauntings. If there is an expectation of a preternatural encounter, it is more likely that one will be perceived or reported.
