A psychic is a person who claims to use powers rooted in parapsychology such as extrasensory perception (ESP) to identify information hidden from the normal senses, particularly involving telepathy or clairvoyance, or who performs acts that are apparently inexplicable by natural laws, such as psychokinesis or teleportation.
