Precognition (from the Latin præ-, “prior to,” cognitio, “a getting to know”) denotes a form of extra-sensory perception where in a person is said to perceive information about places or events through paranormal means before they happen. A related term, presentiment, refers to information about future events which is said to be perceived as emotions. These terms are considered by some to be special cases of the more general term clairvoyance.
