how will you explain if somebody sees some future incident ?

Answer 1

A psychologist might say the brain mis-fired and the signal of what was just seen was stored in our memory and retreived before the image in our eyes made it to our current thought.

Answer 2

This is also called DEJA VU.

The term "déjà vu" (French for "already happened", also called paramnesia) describes the experience of feeling that one has witnessed or experienced a new situation previously. The term was created by a French psychic researcher, Émile Boirac (1851–1917) in his book L'Avenir des sciences psychiques (The Future of Psychic Sciences), which expanded upon an essay he wrote while an undergraduate French concentrator at the University of Chicago. The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eerieness," "strangeness," or "weirdness." The "previous" experience is most frequently attributed to a dream, although in some cases there is a firm sense that the experience "genuinely happened" in the past.

The experience of déjà vu seems to be very common; in formal studies 70% or more of the population report having experienced it at least once. References to the experience of déjà vu are also found in literature of the past, indicating it is not a new phenomenon. While it has been extremely difficult to invoke the déjà vu experience in laboratory settings, therefore making it a subject of few empirical studies, recently researchers have found ways to recreate this sensation using hypnosis

Scientific research

In recent years, déjà vu has been subjected to serious psychological and neurophysiological research. The most likely candidate for explanation is that déjà vu is not an act of "precognition" or "prophecy" but is actually an anomaly of memory; it is the impression that an experience is "being recalled" which is false.[citation needed] This is substantiated to an extent by the fact that in most cases the sense of "recollection" at the time is strong, but any circumstances of the "previous" experience (when, where and how the earlier experience occurred) are quite uncertain. Likewise, as time passes, subjects can exhibit a strong recollection of having the "unsettling" experience of déjà vu itself, but little to no recollection of the specifics of the event(s) or circumstances they were "remembering" when they had the déjà vu experience, and in particular, this may result from an overlap between the neurological systems responsible for short-term memory (events which are perceived as being in the present) and those responsible for long-term memory (events which are perceived as being in the past). However there is much anecdotal evidence that déjà vu is at least sometimes associated with genuine precognition, which the memory anomaly theory does not account for.

Many theorists believe that the memory anomaly is caused when one's conscious mind has a slight delay in receiving perceptive input. In other words, the unconscious mind perceives current surroundings before the conscious mind does. This causes one's conscious self to perceive something that is already in one's memory, even though it was in one's memory only a split second beforeit was perceived.
