How come we get this 'deja vu" (or how do u spell it?)?

Question

I mean why does it happen? did we live before and the life keeps repeating itself and we just get these memory flashes ' oh...I've been here before!' ?

Answer 1

Among the quasi-scientific explanations, what might be called the split-image school holds that two parts of the brain participate simultaneously in the process of perception. If for some reason the impression from part A arrives in one's consciousness out of sync with the impression from part B, one has the sensation of experiencing the the thing twice.

Others explain déjà vu by analogy to a tape recorder. They propose that memory storage is accomplished by means of a "recording head" and memory recall by a "playback head." During déjà vu the two heads are erroneously situated above the same bit of mental blank tape. An experience is thus recorded and remembered simultaneously, with the result that the present is experienced as the past.

There are lots more theories, but you get the idea.

Answer 2

The scientific explanation is:
The most likely candidate for explanation, according to scientists in these fields, 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. 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).

Answer 3

The brain is a machine for learning that does so by attaching something it knows to every stimulus it encounters. Sometimes something registers as a mixed signal of new, but very familiar; be it a place you've never been before, a conversation, etc., ect.

Answer 4

Some scientists think that we share a collective memory .Others think we live in alternative universes (endless possibilities from one point in life).If you think in reincarnation and in meeting the same people over and over again till you fulfill your karma, then that could be it too.But I think it's just the human spirit being related to places , nature and people to a level that we might not ever explain.

Answer 5

i believe that we have deja vu if you will bc we as humans recognize familiar spirits in people or attitudes that are strikingly similar to someone we met or knew before

Answer 6

I think it is memory flashes. your brain can only remember certain things about every situation... your mind will fill in the blanks by its self without your consent.. that is what it is.. want me to explain more contact me....
