What are some theories in reasoning the occurence of deja vu?

The one we assume is 'now', but actually took place before now and it takes awhile for us to 'catch up'....science has already established that our brains are programmed with a delayed reaction anyway.   I think deja vu is due to either reincarnation, or the fact that time is not linear. mail me if you ever want to talk about it...time is one of my favorite subjects in the world, and greatest dilemmas!

I don't know, sometimes that happens with my mom and myself. Like a very vivid dream that makes no sense until a while (sometimes a very long while) later it happens and seems totally normal until you get this rush of deja vou. Or a stream of thoughts that doesn't seem to make any sense, sometimes even about ppl you have yet to meet, you dismiss atthe time, then you have it again later just in daily life and it is like, whoa, that was weird.

These are the major theories for poltergeist phenomena.\n\n***Poltergeist activity originates with agents\n\nPoltergeist activity tends to occur around a single person called an agent or a focus. Foci are often, but not limited to, pubescent children. Almost seventy years of research by the Rhine Research Center in Raleigh-Durham, North Carolina, has led to the hypothesis among parapsychologists that the "poltergeist effect" is a form of psychokinesis generated by a living human mind (that of the agent). According to researchers at the Rhine Center, the "poltergeist effect" is the outward manifestation of psychological trauma.\n\n**Separate existences\n\nPoltergeists might simply exist, like the "elementals" described by occultists.\n\nAnother version posits that poltergeists originate after a person dies in a powerful rage at the time of death. According to yet another opinion, ghosts and poltergeists are "recordings." When there is a powerful emotion, sometimes at death and sometimes not, a recording is believed to be "embedded" in a place or, somehow, in the "fabric of time" itself. This recording will continue to play over and over again until the energy embedded disperses.\n\nHowever some poltergeists have had the ability to articulate themselves and to have distinct personalities, which suggests some sort of self-awareness and intent. Practioners of astral projection have reported the existence of unfriendly astral life forms, which Robert Bruce called "negs" (whom we might also identify with elementals). If they exist, these may well have the ability to affect the physical world.\n\n\n\n **Caused by physical forces\n\nSome scientists propose that all poltergeist activity that they cannot trace to fraud has an explained physical explanation such as static electricity, electromagnetic fields, ultra- and infrasound and/or ionised air. In some cases such as the Rosenheim poltergeist case, the physicist F. Karger from the Max-Planck-Institut für Plasmaphysik and G. Zicha from the Technical University of Munich found neither none of these effects present, and psi proponents claim that no evidence of fraud was ever found, even after a sustained investigation from the police force and CID, though criminologist Herbert Schäfer quotes an unnamed detective watching the agent pushing a lamp when she thought nobody was looking, however if this is true or not police officers did sign statements that they had witnessed the phenomena. John Hutchinson has claimed that he has created poltergeist effects in the lab. Also worth noting is that some scientists now propose that poltergeists and ball lightning may be linked phenomena. Some scientists go as far as calling them pseudo-psychic phenomena and claim that under some circumstances they are caused by obscure physical effects.

It's happened to me many times.  It "could" mean that or many other things too---astral projection, reincarnation, a universal consciousness, memories from our ancestors, various psychic abilities, etc.

First of all...its deja vu.\n\nDeja vu is a French term for "already seen."  So in other words...yes...when you feel like you've seen or done something before, it's deja vu.\n\nWhat you do about it is up to you...you can either learn to learn from what you've seen or done or just simply recognize it as something  you've already seen or done.

The term déjà vu (French: "already seen", 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, Emile 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" or "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.\n\nThe 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. However, in laboratory settings, it is extremely difficult to invoke the déjà vu experience, making it a subject with few empirical studies.\nTypes of déjà vu\nAccording to Arthur Funkhouser there are three types of déjà vu:\n\n[edit]\nDéjà vécu\nUsually translated 'already seen' or 'already lived through,' déjà vécu is described in a quotation from David Copperfield by Charles Dickens:\n\nWe 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![1]\n\nWhen most people speak of déjà vu, they are actually experiencing déjà vécu. Surveys have revealed that about one third of the population have had these experiences, more often (and perhaps more intense) in people between the ages of 15 and 25. The experience is usually related to a very banal event, but is so striking that it is remembered for years afterwards.\n\nDéjà 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. Because of this, theories that the situation was just read about earlier or experienced in a previous life are invalid, as those experiences could not recreate the exact situation due to a lack of sense involvement or the presence of modern surroundings.\n\nMore 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. As described in Moulin, C.J.A., Conway, M.A. Thompson, R.G., James, N. & Jones, R.W. (2005). Disordered Memory Awareness: Recollective Confabulation in Two Cases of Persistent Déjà vecu. Neuropsychologia, 43 :1362-1378.\n\n[edit]\nDéjà senti\nDr. John Hughlings Jackson recorded the words of one of his patients who suffered from temporal lobe or psychomotor epilepsy in an 1889 paper:\n\nWhat 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', &c., but a minute or two later I can recollect

This is NOT DEJAVU. I know, because I experience Deja Vu regularly and it is nothing like you are describing. It sounds like you have a physical condition and I would recommend seeing the doctor immediately... it couldn't hurt just to check it out!

Jamais Vu: From the French, meaning "never seen." The expression explicitly means 'not remembering having seen something before.' The person knows it has happened before, but the experience feels unfamiliar. Often described as the opposite of déjà vu, jamais vu involves a sense of eeriness and the observer's impression of seeing the situation for the first time, despite rationally knowing that he or she has been in the situation before. Jamais vu is sometimes associated with certain types of amnesia and epilepsy. An old internet joke referred to this feeling as "vujà dé."\n\nI've experienced this many times as a result of Lupron injections.  Anyway - hope that helps.

Deja Vu is the illusion of remembering scenes and events when experiencing for the first time.

Would that be "deja vu" that you mean?\n\nHaven't we already seen this?

Sounds like Déja Vu.\n\nIt has been speculated by some that this results from one side of the brain processing information a split second after the other. Thus, one part of your brain experiences an event, and it is recorded there. Then immediately the other side "experiences" the same thing, and it recognizes it as something that has already happened, because it "remembers" what the other side experienced just previous to this.

i guess nobody has ever found a strong proof. ghosts most like ly  appear on human imagination from tales and stories told. well the brain is very powerful to imagine things specially ghostly things.

Deja Vu - Already Seen.\n\nThis can be many things.\n\nJungian theory states that we all have soul memory.  So if you are in a spot that an ancestor was - maybe you have a flashback.\n\nAll animals have instints - These are genetic memories.  Again flashbacks.\n\nSometimes one side of your brain process faster than the other, or you store a current event as memory BEFORE your cognitive side actually mulls over it.\n\nThen somtimes it's a step back in time.\n\nThen sometimes it's a quick premonition.  Like the time I overheard a boy in the front of my class talk to another about his vacation and I knew the whole entire conversation before he actually said it....  But that could be a wierd coincidence.....\n\n....

Oh yeah, I've had those deja' vu instances many times. Especially if it happens to be an older place, maybe a place with some history or legend behind it.  Sometimes it's just nothing more than a coincidence, other times, who knows a leap into something that might have occurred in your past?\nI don't think anyone really knows or understands fully what cases those feelings. It could be something you have lived before if you believe in reincarnation and past lives, it could be that you saw that place or had been to that place when you were younger and only by seeing it or going to it again did it bring back that past memory from your childhood.\n\nMe I believe in Past lives and reincarnation. But that's just me and my opinion on things.

"Déjà vu" litterally means "already seen". It is actually much more used in English than in French. For the meaning, I do agree with Joliet.
