what is deja vu?

Question

i've heard scientific answers about what deja vu is and how it works.Does anyone have any ideas on theories of what this phenomena is?

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".s 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). In other words, the events would be stored into memory before the conscious part of the brain even receives the information and processes it. This would explain why one is, if it ever comes to mind, powerless trying to twist the outcome of the event in order to create a paradox. The delay is only of a few milliseconds, and besides, already happened at the time the conscious of the individual is experiencing it.

Another theory being explored is that of vision. As the theory suggests, one eye may record what is seen fractionally faster than the other, creating that "strong recollection" sensation upon the "same" scene being viewed milliseconds later by the opposite eye. However, this one fails to explain the phenomenon when other sensory inputs are involved, such as the auditive part, and especially the digital part. If one, for instance, experience déjà vu of someone slapping the fingers on his/her left hand, then the déjà vu feeling is certainly not due to his/her right hand to be late on the left one. Also, persons with only one eye still report experiencing déjà vu or déjà vecu. The global phenomenon must therefore be narrowed down to the brain itself (say, one hemisphere would be late compared to the other one).

One of my theories on Deja Vu is that it's a glitch in the brain waves or something like that. I can't really explain it but that's my main theory.

Also, I like how it's explained in the Matrix movie. About how Deja Vu is a mistake in the actual matrix. I can't remember too well, been a while since I saw the movie but I like that theory.

I get deja vu quite a bit too. I experienced it a lot more when I was younger than I do now . I'm not sure if that means anything.

Answer 3

The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eeriness", "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. Déjà vu has been described as "remembering the future." See spirit explanation below.

The experience of déjà vu seems to be very common; in formal studies 70% of people 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. 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.

It's a trick in the brain, where all the sudden you just "know" you've experienced a moment before. You feel like your watching a repeat of a movie, but it's real life. You almost feel you can predict what happens next.

I love when that happens to me, but I've only experienced it maybe 3 times in my whole life.

Answer 5

well first of all in french it means "already seen".
it's something when you feel like when something happens you feel like it's already happened and you can almost predict what will happen next. it happens to me all the time and it's really cool. you feel like maybe you've seen that moment in adream or whatever that's what i feel like.
in my relgion we believe that before we go into our mother's stomach, our soul sees what we will do, every detail, of our life, so when we live the moments, sometimes we remember what we saw, and so we feel like we've lived the moment twice. i only heard that from one person though, dunno how true it is but it kinda makes sense. hope that helps. :)

Answer 6

im sure a lot of people here will answer your question in medical terms so I wont bother.

But all i can say is that I think it's a really cool feeling.

Answer 7

It's a glitch in the matrix. It happens whenever they change something. The agents are on their way ...
