Many feel that the strangest, and most interesting, aspect of parapsychological phenomena is that they do not appear to be limited by the known boundaries of space or time. In addition, they blur the sharp distinction usually made between mind and matter. In popular usage, the basic parapsychological phenomena are categorized as follows:

ESP: Extra-sensory perception; a general term for obtaining information about events beyond the reach of the normal senses. This term subsumes telepathy, clairvoyance, precognition, and presentiment
.
Clairvoyance: Sometimes called remote viewing; obtaining information about events at remote locations, beyond the reach of the normal senses.

Precognition: Also called premonition. Obtaining information about future events, where the information could not be inferred through normal means. Many people report dreams that appear to be precognitive.

Presentiment: This is where physiological parameters may change prior to the application of a stimulus, suggestive of the fact that on an unconscious level the person knew what was coming before it occurred (and before it was even randomly chosen).

Telepathy: Direct mind-to-mind communication.

Mind-Matter Interaction: Previously known as psychokinesis or PK; direct mental interaction with physical objects, animate or inanimate.

Anpsi: Psi in animals.

NDE: Near death experience; an experience reported by those who were revived from nearly dying. Often refers to a core experience that includes feelings of peace, OBE, seeing lights and other phenomena.

OBE: Out-of-body experience; the experience of feeling separated from the body, often accompanied by visual perceptions as though from above the body.

Reincarnation: The belief that we live successive lives, with primarily evidence coming from the apparent recollections of previous lives by very small children.

Haunting: Recurrent phenomena reported to occur in particular locations that include apparitions, sounds, movement of objects, and other effects.

Place Memory: the apparent ability of a building or location to hold recorded impressions of people and events that transpired in the past.

Poltergeist: Large-scale PK phenomena often attributed to spirits, but which are now thought to be due to a living person or group of people. Although reported in all age groups, the agent is most frequently an adolescent.

Psi: A neutral term for parapsychological phenomena, inclusive of both ESP and mind-matter interaction. Psi, psychic, and psychical are synonyms.
