Do you have ideas about daja vu?

Question

As many of us experience so frequently that it can't be ignored, the feeling of some situation, some moment, be it a place and conversation etc, have occured more than once. Term given for this is deja vu. Many psychologists are searching for its biological basis, but I want to share my feeling here.
You know, the situations when we have deja vu are specific. I say they ARE repeating, somehow. Suppose u met a fren and said, "Oh, what a good colour shirt!...." and thinking about the colour of your scooter of same colour. Now, suppose in this moment, you felt deja vu. But in reality it hasn't happened previously.
My question is, can it happen in FUTURE? The same situation, saying about colour of shirt and thinking about your scooter in the same line...? So that next time you have same situation, again you feel deja vu,...This time mind catching correctly as happening for second time?
Neurlolgists say that mind works in a specific way and its action can be predicted. Plz reply in short

Answer 1

The term "déjà vu" (IPA:/deʒa vy/) (French for "already seen", also called paramnesia) describes the experience of feeling that one has witnessed or experienced a new situation previously. The term was coined 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 "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."

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. 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.

According to Arthur Funkhouser there are three major types of déjà vu.

Déjà vécu
Usually translated ' already seen' or 'already lived through,' déjà vécu is described in a quotation from Charles Dickens:

“ We have all some experience of a feeling, that comes over us occasionally, of what we are saying and doing having been said and done before, in a remote time – of our having been surrounded, dim ages ago, by the same faces, objects, and circumstances – of our knowing perfectly what will be said next, as if we suddenly remember it!”

When most people speak of déjà vu, they are actually experiencing déjà vécu. Surveys have revealed that as much as 70% of the population have had these experiences, usually between ages 15 to 25, when the mind is still subjectable to noticing the change in environment. The experience is usually related to a very banal event, but is so striking that it is remembered for years afterwards.

Déjà vécu refers to an experience involving more than just sight, which is why labeling such "déjà vu" is usually inaccurate. The sense involves a great amount of detail, sensing that everything is just as it was before.

More recently, the term déjà vécu has been used to describe very intense and persistent feelings of a déjà vu type, which occur as part of a memory disorder.

Déjà senti
This phenomenon specifies something 'already felt.' Unlike the implied precognition of déjà vécu, déjà senti is primarily or even exclusively a mental happening, has no precognitive aspects, and rarely if ever remains in the afflicted person's memory afterwards.

Dr. John Hughlings Jackson recorded the words of one of his patients who suffered from temporal lobe or psychomotor epilepsy in an 1889 paper:

“ What is occupying the attention is what has occupied it before, and indeed has been familiar, but has been for a time forgotten, and now is recovered with a slight sense of satisfaction as if it had been sought for. ... At the same time, or ... more accurately in immediate sequence, I am dimly aware that the recollection is fictitious and my state abnormal. The recollection is always started by another person's voice, or by my own verbalized thought, or by what I am reading and mentally verbalize; and I think that during the abnormal state I generally verbalize some such phrase of simple recognition as 'Oh yes – I see', 'Of course – I remember', but a minute or two later I can recollect neither the words nor the verbalized thought which gave rise to the recollection. I only find strongly that they resemble what I have felt before under similar abnormal conditions. ”

As with Dr. Jackson's patient, some temporal-lobe epileptics may experience this phenomenon.

Déjà visité
This experience is less common and involves an uncanny knowledge of a new place. The translation is "already visited." Here one may know his or her way around in a new town or landscape while at the same time knowing that this should not be possible.

Dreams, reincarnation and also out-of-body travel have been invoked to explain this phenomenon. Additionally, some suggest that reading a detailed account of a place can result in this feeling when the locale is later visited. Two famous examples of such a situation were described by Nathaniel Hawthorne in his book Our Old Home and Sir Walter Scott in Guy Mannering. Hawthorne recognized the ruins of a castle in England and later was able to trace the sensation to a piece written about the castle by Alexander Pope two hundred years earlier.

C. G. Jung published an account of déjà visité in his 1952 paper On synchronicity.

In order to distinguish déjà visité from déjà vécu, it is important to identify the source of the feeling. Déjà vécu is in reference to the temporal occurrences and processes, while déjà visité has more to do with geography and spatial relations.


Scientific research
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).

Links with disorders
A clinical correlation has been found between the experience of déjà vu and disorders such as schizophrenia and anxiety, and the likelihood of the experience considerably increases with subjects having these conditions. However, the strongest pathological association of déjà vu is with temporal lobe epilepsy. This correlation has led some researchers to speculate that the experience of déjà vu is possibly a neurological anomaly related to improper electrical discharge in the brain. As most people suffer a mild (i.e. non-pathological) epileptic episode regularly (e.g. the sudden "jolt", a hypnagogic jerk, that frequently occurs just prior to falling asleep), it is conjectured that a similar (mild) neurological aberration occurs in the experience of déjà vu, resulting in an erroneous sensation of memory.

Pharmacology
It has been reported that certain recreational drugs increase the chances of déjà vu occurring in the user. Some pharmaceutical drugs, when taken together, have also been implicated in the cause of déjà vu. Taiminen and Jääskeläinen (2001) reported the case of an otherwise healthy male who started experiencing intense and recurrent sensations of déjà vu on taking the drugs amantadine and phenylpropanolamine together to relieve flu symptoms. He found the experience so interesting that he completed the full course of his treatment and reported it to the psychologists to write-up as a case study. Due to the dopaminergic action of the drugs and previous findings from electrode stimulation of the brain (e.g. Bancaud, Brunet-Bourgin, Chauvel, & Halgren, 1994), Taiminen and Jääskeläinen speculate that déjà vu occurs as a result of hyperdopaminergic action in the mesial temporal areas of the brain.

Memory-based explanations
The similarity between a déjà vu-eliciting stimulus and an existing, but different, memory trace may lead to the sensation. Thus, encountering something which evokes the implicit associations of an experience or sensation that cannot be remembered may lead to déjà vu. In an effort to experimentally reproduce the sensation, Banister and Zangwill (1941) used hypnosis to give participants posthypnotic amnesia suggestions for material they had already seen. When this was later re-encountered, the restricted activation caused by the posthypnotic amnesia resulted in three of the 10 participants reporting what the authors termed paramnesias. Memory-based explanations may lead to the development of a number of non-invasive experimental methods by which a long sought-after analogue of déjà vu can be reliably produced that would allow it to be tested under well-controlled experimental conditions.

Neural theories
In the late 19th and early 20th Centuries, it was widely believed that déjà vu could be caused by the mis-timing of neuronal firing. This timing error was thought to lead the brain to believe that it was encountering a stimulus for the second time, when in fact, it was simply re-experiencing the same event from a slightly delayed source. A number of variations of these theories exist, with miscommunication of the two cerebral hemispheres and abnormally fast neuronal firing also given as explanations for the sensation. Perhaps the most widely acknowledged neuronal theory is the optical pathway delay theory which explains déjà vu as being the product of a delayed optical input from one eye. Closely following the input from the first eye (when it should be simultaneous), this misleads conscious awareness and suggests a sensation of familiarity when there should not be one. Although intuitively plausible, this theory is untestable due to the minute times involved in neuronal firing, and inconsistent with reports that blind individuals experience déjà vu in the same way as sighted individuals (O'Connor & Moulin, 2006).

Parapsychology
Déjà vu is associated with precognition, clairvoyance or extra-sensory perceptions, and it is frequently cited as evidence for "psychic" abilities in the general population. Non-scientific explanations attribute the experience to prophecy, visions (such as received in dreams) or past-life memories. by T.kBaller

Dreams
Some believe déjà vu is the memory of dreams. Though the majority of dreams are never remembered, a dreaming person can display activity in the areas of the brain that process long-term memory. It has been speculated that dreams read directly into long-term memory, bypassing short-term memory entirely. In this case, déjà vu might be a memory of a forgotten dream with elements in common with the current waking experience. This may be similar to another phenomenon known as déjà rêvé, or "already dreamed."

Not only is the link to dreams as they pertain to déjà vu the subject of scientific and psychological studies, it is also a subject of spiritual texts, as is found in, for example, in the writings of the Bahá'í Faith with quotes like "...perchance when ten years are gone, thou wilt witness in the outer world the very things thou hast dreamed tonight." and "Behold how the thing which thou hast seen in thy dream is, after a considerable lapse of time, fully realized."

Reincarnation
Those believing in reincarnation theorize that déjà vu is caused by fragments of past-life memories being jarred to the surface of the mind by familiar surroundings or people. Others theorize that the phenomenon is caused by astral projection, or out-of-body experiences (OBEs), where it is possible that individuals have visited places while in their astral bodies during sleep. The sensation may also be interpreted as connected to the fulfillment of a condition as seen or felt in a premonition. For further cases of remembering information from past lives, see Ian Stevenson.

Answer 2

I often dream things beforehand and then they happen. Small things, like looking at something at a certain angle, or hearing a joke. I get that commonly. I don't know if I am actually seeing the future at all since I never seem to remember the dream until it does happen. I have a strong feeling of time, like yes I did this WAY before. I'd like to think otherwise, but the other answer to the question so far says it's a misfiring of the brain. While I doubt it, I cannot and would not eliminate this as a possibility.

Answer 3

well i haven't read any literature on 'deja vu' as such. what i can tellu frm my experience is this,
like u said deja vu is a feeling that the situation have occurred once in the past. but i have experienced certain moments which i had not experienced earlier,but i did experience them few years later.

although the moment wasnt remarkable n dint influence my life during that time , i was really spooked by it.
there is no explanations to such things, n we shouldnt think too much bout it i guess. like they say " sometimes ,**** happens "

Answer 4

the area of the brain responsible for deja vu, deja visite, and deja suenci, was identified long ago. I've read the other answers, and I disagree. I don't recall ever seeing any other explanation of why 75% of all people experience this "seen before" phenomonon, other than it is the result of the poverty of our human brain.

Answer 6

Look into Remote Viewing. As to how this is possible might be because there is something about us that is immortal and always present that gives us a certain amount of intuition or second sight. Many may even believe we have had previous and future lives etc. Maybe some of us were extraterrestrials at one time also. Others might really believe we live in a program or Matrix.

Answer 7

Deja vu means you are basically recalling a circumstance at the same time you are remembering it. It's pretty well understood and explained. Here's something from YAHOO answers.

Sure I told you this Before that you just wouldn't listen so now stop take a deep breath and sure I told this Before its very similar to Breathing Just remember to keep doing it and you'll be able to recall that Sure I told you this before! foresure Peter

Answer 11

It's a misfiring in your brain, causing your brain to file a new experience as a repeated one. That's all.
