Deja Vu: All Over Again
By Gunner Glam
Ever had the feeling new activities had been experienced before? Sensing exact same conditions? See and hear the same thing before? This is at times confusing because at the people are not able to remember when and where these activities were performed.
It is as in a dream, but why and how could actually happen. This is the mystery of Déjà Vu and Studio Brow would like to let you know the ways the past can repeat itself.
Literally translated to, “already seen,” Déjà vu is the experience of feeling sure that one has already witnessed or experienced a current situation, even though the exact circumstances of the prior encounter are uncertain and were perhaps imagined.
The term was coined 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.
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.
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 false impression that an experience is “being recalled.”
This explanation is supported by the fact that the sense of “recollection” at the time is strong in most cases, but that the circumstances of the “previous” experience such as when, where and how the earlier experience occurred, are quite uncertain or believed to be impossible.
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 for long-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.
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 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 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 “cryptomnesia,” 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.”
Presque vu (Tip of the tongue)
Déjà vu is similar to, but distinct from, the phenomenon called tip of the tongue, a situation in which when one cannot recall a familiar word or name, 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.”
Film
Déjà vu provides a plot point in The Matrix, a 1999 science fiction-action film written and directed by Larry and Andy Wachowski. The protagonist, Neo, glances at a black cat and comments that he has just experienced déjà vu. Those with a knowledge of ‘The Matrix’ and its internal workings state that déjà vu means something within the Matrix was altered from its prior state and is referred to as a “glitch.”
The 2006 science fiction film Déjà vu revolves around a US federal law enforcement officer using an instrument called Snowhite to view the past 4 and a half days of anywhere in the world (limited radius as permissible by the program) in order to solve a murder and a terrorist bomb attack on a ferry that was being boarded by about 500 citizens and military members.
Further Research
According to the web site, Psychology face, it is not merely a natural phenomenon that can not be explained scientifically because scientists have found an answer to the phenomena that exist in the human mind. Déjà vu occurs because of a wave that is delivered into the brain.
Waves are created by every action taken by humans. These waves are then translated into electrical impulses and sent to the brain and interpreted.
There are times when the human brain has a high sensitivity so the waves were read in the form of a certain amplitude and frequency depending on the quality of the brains.
A simple example is when people hum a song. Later people could turn on the radio and it is playing songs that were being thought of earlier.
People immediately think “déjà vu”. In fact, this shows that the radio waves sent by the transmitting station, as well accepted by the radio, also read by human brains because of the nature of the brain is super-sensitive in receiving electric waves that were airing.
