Precognition is the ability to see into the future. The direct knowledge or perception of the future, obtained through extrasensory means. Precognition is the most frequently reported of all extrasensory perception experiences, occurring most often in dreams. It may also occur spontaneously in waking visions, auditory hallucinations, migraines, flashing thoughts entering the mind, and the sense of "knowing."
Prophecy is thought to be a divinely inspired vision or revelation of forthcoming events of such a magnitude that will possibly affect races, groups, or countries. Most, if not all, prophecies come from precognition, or knowledge of the future, but not all precognitive experiences are prophecies, the key difference being recognized as the divine spark or inspiration
Premonition is a type of prophecy consisting of an impressionable warning of a future event. The phenomenon is characterized by such sensations as anxiety, uneasiness, a vague feeling of disquiet suggesting impending disaster to actual visual or auditory hallucinations. Premonition is sometimes referred to as a "gut-level" feeling. The sensation tends to occur prior to disasters, accidents, deaths and other traumatic and emotionally charged events. The sensation of premonition may be considered precognition at times because there is no clear-cut line between them. However, generally premonitions are sense-oriented, dominated by a syndrome of physical uneasiness, depression, or distress that is without discernible source or reason. It is an unexplainable feeling that "something is going to happen." Precognition, on the other hand, is more precise, involving visions or dream of the event that is to occur in the future. A premonition is a noun for: a feeling of anticipation of or anxiety over a future event; presentiment. It can also be described as a forewarning.
Oneiromancy (Precognitive Dreaming) is a form of divination based upon dreams; it is a system of dream interpretation that uses dreams to predict the future.
