Parapsychology is the study of alleged psychic phenomena and other paranormal claims, for example, those related to near-death experiences, synchronicity, apparitional experiences, etc. Criticized as being a pseudoscience, the majority of mainstream scientists reject it. Parapsychology has also been criticized by mainstream critics for claims by many of its practitioners that their studies are plausible despite a lack of convincing evidence after more than a century of research for the existence of any psychic phenomena.
In German folklore and ghostlore, a poltergeist 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.
The Society for Psychical Research (SPR) is a nonprofit organisation in the United Kingdom. Its stated purpose is to understand events and abilities commonly described as psychic or paranormal. It describes itself as the "first society to conduct organised scholarly research into human experiences that challenge contemporary scientific models."

No scientific study has ever been able to confirm the existence of ghosts. Ghost hunting is considered a pseudoscience by the vast majority of educators, academics, science writers and skeptics. Science historian Brian Regal described ghost hunting as "an unorganized exercise in futility".

Psychic archaeology is a loose collection of practices involving the application of paranormal phenomena to problems in archaeology. It is not considered part of mainstream archaeology, or taught in academic institutions. It is difficult to test scientifically, since archaeological sites are relatively abundant, and all of its verified predictions could have been made via educated guesses.
