Apa yang ada dipikiran Anda waktu mengalaminya? Aneh? Seru? Atau menyeramkan? Dulu waktu awal-awal mengalaminya, saya hanya merasakan aneh dan berusaha mengingat-ingat. Tapi lama-lama… hal itu cukup menyeramkan. Seperti sebuah mimpi misterius yang sulit dipecahkan. Atau mungkin sebuah peringatan dari Allah agar kita tidak mengulangi kesalahan yang sama?
Untuk menjelaskan hal misterius ini, berbagai teori berusaha menjelaskan termasuk yang mengatakan bahwa déjà vu berkaitan dengan mimpi. Tapi dalam mimpi pun kadang kita sulit menjelaskan atau mengingatnya (bahkan saya ikut-ikutan sulit menjelaskan tulisan ini 
) Tapi mungkin Anda juga ingat sabda Nabi, “Manusia itu tidur, dan tatkala mereka mati barulah mereka bangun.”
Kita semua ini masih “tidur”, semua yang ada hanyalah mimpi, tidak nyata. Ketika kita selalu mengingat hal ini, maka semua beban akan lepas. Semua masalah menjadi ringan karena kita yakin di dunia ini kita sementara, masalah dunia hanyalah masalah sepele. Ketika kita mengalami déjà vu, carilah hikmah bahwa itu adalah peringatan dari Allah agar kita berhati-hati dalam berbuat.
Kita tidak ingin berteriak seperti ini: “Aduh celakalah kami! Siapakah yang membangkitkan kami dari tempat tidur kami?” (QS. Yâsin : 52) Kita juga tidak mau mengeluh: “Ya Tuhanku kembalikanlah aku (ke dunia), agar aku berbuat amal yang shaleh terhadap yang telah aku tinggalkan.” (QS. Al-Mu’minûn: 99-100) Lalu kita teringat ayat ini: “Dan tiadalah kehidupan dunia ini melainkan senda gurau dan main-main. Dan sesungguhnya akhirat itulah yang sebenarnya kehidupan...” (QS. Al-Ankabût: 64). Wallahualam.
Déjà vu (French pronunciation: [deʒa vy] (
listen), meaning "already seen") is the experience of feeling sure that one has already witnessed or experienced a current situation, even though the exact circumstances of the previous encounter are uncertain and were perhaps imagined. 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. The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eeriness," "strangeness," "weirdness," or what Sigmund Freud calls "the uncanny." The "previous" experience is most frequently attributed to a dream, although in some cases there is a firm sense that the experience has genuinely happened in the past.[1]
The experience of déjà vu seems to be quite common among adults and children alike. References to the experience of déjà vu are found in literature of the past,[2] indicating it is not a new phenomenon. It has been extremely difficult to evoke the déjà vu experience in laboratory settings, therefore making it a subject of few empirical studies. Certain researchers claim to have found ways to recreate this sensation usinghypnosis.[3]

Scientific research
The most likely explanation of déjà vu is not that it is an act of "precognition" or "prophecy," but rather that it is an anomaly of memory, giving the impression that an experience is "being recalled." 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 or 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 and those responsible forlong-term memory (events which are perceived as being in the past). The events would be stored into memory before the conscious part of the brain even receives the information and processes it.[citation needed]
Another theory being explored is that of vision. The theory suggests that one eye may record what is seen fractionally faster than the other, creating the "strong recollection" sensation upon the "same" scene being viewed milliseconds later by the opposite eye.[4] However, this theory fails to explain the phenomenon when other sensory inputs are involved, such as hearing or touch. If one, for instance, experiences déjà vu of someone slapping the fingers on his left hand, then the déjà vu feeling is certainly not due to his right hand experiencing the same sensation later than his left hand considering that his right hand would never receive the same sensory input. Also, people with only one eye still report experiencing déjà vu or déjà vécu (a rare disorder of memory, similar to persistent déjà vu). The global phenomenon can therefore at least in certain cases be narrowed down to the brain itself (i.e., one hemisphere being late compared to the other one).
Links with disorders
Early researchers tried to establish a link between déjà vu and serious psychopathology such as schizophrenia, anxiety, and dissociative identity disorder, with hopes of finding the experience of some diagnostic value. However, there does not seem to be any special association between déjà vu and schizophrenia or other psychiatric conditions.[3] The strongest pathological association of déjà vu is with temporal lobe epilepsy.[5][6] 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. ahypnagogic jerk, the sudden "jolt" that frequently, but not always, 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. For someone who regularly has such seizures, there is typically a feeling of déjà vu associated with whatever sensations (particularly sounds) may be occurring nearby.[citation needed]
Pharmacology
It has been reported that certain 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)[7] reported the case of an otherwise healthy male who started experiencing intense and recurrent sensations of déjà vu upon taking the drugs amantadine and phenylpropanolaminetogether 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.[8]) Taiminen and Jääskeläinen speculate that déjà vu occurs as a result of hyperdopaminergic action in the mesial temporal areas of the brain. Many scientists[which?] are still working towards the actual link of déjà vu with hypnagogic epilepsy.
Memory-based explanations
The similarity between a déjà-vu-eliciting stimulus and an existing, but different, memory trace may lead to the sensation.[3][9] 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)[10][11] used hypnosis to give participants posthypnotic amnesia for material they had already seen. When this was later re-encountered, the restricted activation caused thereafter 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. Cleary[9] suggests that déjà vu may be a form of familiarity-based recognition (recognition that is based on a feeling of familiarity with a situation) and that laboratory methods of probing familiarity-based recognition hold promise for probing déjà vu in laboratory settings. Another possible explanation for the phenomenon of déjà vu is the occurrence of "cryptamnesia", which is where information learned is forgotten but nevertheless stored in the brain, and similar occurrences invoke the contained knowledge, leading to a feeling of familiarity because of the situation, event or emotional/vocal content, known as "déjà vu".
Related phenomena
Jamais vu
Jamais vu (from French, meaning "never seen") is a term in psychology which is used to describe any familiar situation which is not recognized by the observer.
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 more commonly explained as when a person momentarily does not recognize a word, person, or place that they already know.
Jamais vu is sometimes associated with certain types of amnesia and epilepsy.
Theoretically, as seen below, a jamais vu feeling in a sufferer of a delirious disorder or intoxication could result in a delirious explanation of it, such as in the Capgras delusion, in which the patient takes a person known by him/her for a false double or impostor. If the impostor is himself, the clinical setting would be the same as the one described as depersonalisation, hence jamais vus of oneself or of the very "reality of reality", are termed depersonalisation (or surreality) feelings.
Times Online reports:
Chris Moulin, of the University of Leeds, asked 95 volunteers to write out "door" 30 times in 60 seconds. At the International Conference on Memory in Sydney last week he reported that 68 percent of the volunteers showed symptoms of jamais vu, such as beginning to doubt that "door" was a real word. Dr. Moulin believes that a similar brain fatigue underlies a phenomenon observed in some schizophrenia patients: that a familiar person has been replaced by an impostor. Dr. Moulin suggests they could be suffering from chronic jamais vu.[12]
Presque vu (Tip of Tongue)
Déjà vu is similar to, but distinct from, the phenomenon called tip of the tongue which is when one cannot recall a familiar word or name or situation, but with effort one eventually recalls the elusive memory. In contrast, déjà vu is a feeling that the present situation has occurred before, but the details are elusive because the situation never happened before.
Presque vu (from French, meaning "almost seen") is the sensation of being on the brink of an epiphany. Often very disorienting and distracting, presque vu rarely leads to an actual breakthrough. Frequently, one experiencing presque vu will say that they have something "on the tip of my tongue".
Presque vu is often cited by people who suffer from epilepsy or other seizure-related brain conditions, such as temporal lobe lability.
DEJA VU TIED TO FAMILIARITY TO THE PAST DEJA VU TIED TO FAMILIARITY TO THE PAST
December 1 2008
Fort Collins, CO – Déjà Vu, the feeling that you have been in the same place experiencing the same thing, is something that has affected all of us at one point or another, or another. Now researchers have uncovered a possible reason for the occurrence, though the explanation comes as little surprise to those experiencing the phenomenon again and again.
“Many parallels between explanations of déjà vu and theories of human recognition memory exist,” said Anne Cleary of Colorado State University. “Theories of familiarity-based recognition and the laboratory methods used to study it may be especially useful for elucidating the processes underlying déjà vu experiences.”
A report published in Current Directions in Psychological Science states that déjà vu occurs when a current situation resembles a situation that has previously occurred in one’s life. When multiple elements of the two situations overlap, the feeling of familiarity is sparked.
“What we found was that people retain fragments of memory and they then subconsciously reconstruct the occurrence,” continued Cleary. “The mind fills in the gaps and it appears as though an event is reoccurring, but it is an entirely new happening.”

The researchers hope that they can use this research to uncover some of the mysteries of the human mind, and do away with the notion that Déjà Vu is somehow a mystical or otherworldly experience.
“We want people to understand that these are not visions into the past, at least not in the traditional sense,” continued Cleary. “Memories obviously give us a foothold in the past and our recollection of them is a form of time travel. We do want people to understand that this is an occurrence of the human condition though and not something mystical.”
Of course most in the scientific community have long dismissed the idea of the happenings of Déjà Vu as anything other than a natural occurrence of the human brain. Even those less familiar with the scientific logic behind the occurrence generally dismiss it as little more than an interesting occurrence.
“I don’t know of anyone who has seen déjà vu as anything other than a neat little thing that happens occasionally. I don’t know of anyone who came away from one of those experiences believing they had somehow just had some kind of vision,” said Scrape TV Science analyst Dr. Howard Poe. “”Research into the oddities of the human mind and human experience can be nothing but beneficial, but there comes a time when researchers end up telling us exactly what we knew or suspected all along. Logic it seems doesn’t come into play when it comes to grant money. Nonetheless, someone could probably use this research for something, someday, as long as they remember it was done.”
