A ghost is said to be the apparition of a deceased person, frequently similar in appearance to that person, and usually encountered in places he or she frequented, or in association with the person's former belongings. The word "ghost" may also refer to the spirit or soul of a deceased person, or any spirit or demon.[1][2][3] Ghosts are often associated with hauntings, which is, according to the Parapsychological Association, "the more or less regular occurrence of paranormal phenomena associated with a particular locality (especially a building) and usually attributed to the activities of a discarnate entity; the phenomena may include apparitions, poltergeist disturbances, cold drafts, sounds of footsteps and voices, and various odors."[2]
Ghosts are a controversial anomalous phenomenon. According to a poll conducted in 2005 by the Gallup Organization, about 32% of Americans believe in the existence of ghosts.[4] The term ghost has been replaced by apparition in parapsychology, because the word ghost is deemed insufficiently precise.[5]
Do you guys agree? Should we throw out the term ghost and interchange it with words like apparition,
poltergeist, etc.? Does it make it more scientific if we adapt to parapsychology standards and change our verbiage and give this unknown thing different terms
to adapt to the different situations in which they are encountered? Are we using different terms to fit with the data we are getting?
