Deja Vu? whats that? how and why it occurs? and why?

Question

Please answer! that is a mystery for me for quite some time.

Answer 1

In recent years, déjà vu has been subjected to serious psychological and neurophysiological research. The most likely explanation of déjà vu is that it is not an act of "precognition" or "prophecy", but rather an anomaly of memory; it is the impression that an experience is "being recalled". [citation needed] This explanation is substantiated by the fact that the sense of "recollection" at the time is strong in most cases, but that the 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 circumstance(s) they were "remembering" when they had the déjà vu experience. 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). Many theorists believe that the memory anomaly occurs 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 before it was perceived.

Answer 2

well deja vu is supposedly kinda simple, when one sees something instead of processing it a certain way like we always do we run the image or moment of action through our memory first and then recall it, so as to say i see a dog barking, i first store it in memory and then recall it, which seems that i have been there or seen that before, instead of recalling it first and then storing it in memory, kinda simple if u think bout it

Answer 3

Deja vu is a glitch in the Matrix, it happens when they change something.
