Some terms used in the paranormal investigation field that may be helpful:
Haunting: The manifestation of a ghostly presence, or presences, attached to a specific locale. Hauntings can be categorized into four (usually) distinct types, these being Intelligent (responsive), Poltergeist (likely initiated by pent-up stress on a subconcious level), Residual (replay) and Demonic (non-human origin). See also "Infestation."
Infestation: Repeated and persistent paranormal phenomena, generally centered around a particular location or person(s). Also known as a haunting.
Residual (Haunting): Psychic imprint of a scene which is repeatedly played out, where the witness of such phenomenon essentially is peering into the past. The ghostly participants of these time-displacements often seem unaware of their living observer.
Intelligent (Haunting): A haunting by a responsive entity, and dynamic in nature unlike a residual haunting. A characteristic of an intelligent haunting is the ability of the phenomenon imposed by the entity to have free will or to make conscious decisions.
Ghost: The image of a person witnessed after his/her death, reflecting the appearance of the living, physical body yet less substantial. These forms often seem to exist in a dream-like state of semi-awareness, at times though not always cognizant of their human observers.
Spirit: Existence apart from, or transcending, the purely physical; also, the life-force of an organism. A spirit commonly refers to a ghost.
Entity: A disembodied "consciousness" commonly referred to as ghost, spirit or (if of an apparently malicious or resentful nature) demon.
Apparition: The projection or manifestation of a quasi-physical entity.
Demon: Hostile and resentful entity, supposedly of non-human origin, which some believe to be "fallen (from grace) angels."
Poltergiest: German for "noisy ghost." This is an extremely rare occurance wherein random objects are moved and sounds produced by an unseen force, the sole purpose of which seems to be to draw attention to itself. The phenomenon always involves a specific individual, frequently a child or adolescent.
Wraith/Wrayth: The image of a person appearing shortly before or after his or her death; term can also be applied to a ghost.
Lepke: A very unique and interesting type of spiritual manifestation, a ghost which has the appearance of a solid, living person, may even converse with someone, then suddenly vanishes. "We were talking, I turned to face her again, and she was just gone!" Such apparitions are most often reported to have been encountered within, or immediately outside of cemeteries.
E.V.P (which stands for "Electronic Voice Phenomena"): Disembodied "voices" and sounds imprinted on audio recording devices.
Anomaly: An occurance or condition removed from ordinarily understood experience. See also: Paranormal
Paranormal: The realm of occurances and phenomena removed from those to which people are accustomed and comprehend, and presently uncategorized by standard academia.
