Postcognition is a paranormal ability. It is possessed by psychics, oracles, prophets, clairvoyants and some mutants and witches. It represents the ability to perceive events that have already taken place even if the user was not a direct witness to the event. For example, a psychic residing in Oregon may psychically have a vision of a murder that took place in New Jersey, even though they are in a different location and have no alternative insight to the event.
