Every field has its own language and this one is no exception. Dr. Dean Radin has been kind enough to provide us with a primer of often used terms:

Clairvoyance: Information received from a distance, beyond the reach of the ordinary senses. A French term meaning “clear-seeing”. Also called “remote viewing”.

ESP: Extrasensory perception, a term popularized by J. B. Rhine in the 1930’s. It refers to information perceived by telepathy, clairvoyance, or precognition.

Haunting: Recurrent phenomena reported to occur in particular locations, including sightings of apparitions, strange sounds, movement of objects, and other anomalous physical and perceptual effects. Related to psi by similarities to psychokinesis and clairvoyance.

NDE: Near-death experience; an experience sometimes reported by those who are revived from nearly dying. Often refers to a core experience that includes feelings of peace, OBE, seeing lights, and certain other phenomena. Related to psi primarily through the OBE experience.

OBE: Out-of-body experience; an experience of feeling separated from the body. Usually accompanied by visual perceptions reminiscent of clairvoyance.

Precognition: Information perceived about future events, where the information could not be inferred by ordinary means. Variations include “premonition”, a foreboding of an unfavorable future event, and “pre sentinent,” a sensing of future emotion.

psi: A letter of Greek alphabet (Ψ) used as a neutral term for all ESP-type and psychokinetic phenomena.

Psychokinesis: Mental interaction with animate or inmate matter. Experiments suggest that is more accurate to think of psychokinesis as information flowing from mind to matter, rather than as the application of mental forces or powers. Also called “mind-matter interaction,” “PK”, and sometimes, “telekinesis.”

Reincarnation: The concept of dying and being reborn into a new life. The strongest evidence for this ancient idea comes from children, some of whom recollect verifiable details of previous lives. Related to psi by similarities to clairvoyance and telepathy.

Telepathy: Information exchanged between two or more minds, without the use of the ordinary senses.
