When you go to a theme park, did you ever feel that you visited this park before? Or to a place where you feel exactly its a place you have been here but when, you can't remember. Its Deja Vu, kinda different name, many of us would have probably heard about it but of us have experienced it, probably some of them are unaware of what that situation might be called. Well, not a problem for those who do not know about it, lets discuss it, from its little history to present meaning.
In 1876,
French scientist Emile Boirac named the strange phenomenon in which a person sometimes get a glimpse of an object or a situation to a full conscious perception, which results into a false sense of familiarity known as Déjà vu which is a French term that means "already seen" also there are similar words such as already experienced which is déjà vécu, also déjà senti is already thought; and déjà visité is already visited.
A false impression of feeling of objects and situations that can be recollected from unsettling experience with a remembrance of a strong feeling that happened before, which actually did not happened, is what Deja vu being known for. There are sometimes which follow specific events and circumstances where we feel the remembrance works on the fact that result from an overlap between the neurological systems responsible for short-term memory. Looking it logically, one reason could be that events could be stored into memory in the concious part of the brain and another could be brain processes the sensory input as a memory, and during the event one believes it to be a past memory, yet it is only a memory-in-progress.
Believe it or not, earlier there were serious links attached to Deja vu with schizophrenia, also other psychiatric conditions but theory in reality have failed to establish a link. Although there is pathological association of Deja vu with temporal lobe epilepsy and alzheimer's which speculated the fact of neurological anomaly related to improper electrical discharge in the brain. It is possible phenomena that people can suffer from mild epilepsy and it is conjectured that a mild neurological aberration occurs in Deja vu, resulting in an erroneous sensation of memory. Certain pharmaceutical drugs can increase the chances of Deja vu.
It would be interesting to know that some parapsychologist like Ian Stevenson have explained that Deja vu can be explained on the basis of reincarnation. Anthony Peake mentioned that people are living their lives not for the first time but at least the second. In India, the belief of Deja vu is related to the occurrence or repetition of things and situations, as past is believed not to be dead, what is seen in present has Deja vu only because it will occur in the future and so there is sense of familiarity in the present. Past, present and future continuously works in there parallel universe, they can never go, they will remain forever.
Isn't it interesting, Deja vu, but there are other concepts like Deja Vu.
Jamais vu is a French word meaning "never seen". Jamais vu makes believe the observer that situation is not familiar or it is seen for the first time, but it is only in a situation when the observer has seen it before also. In Jamais vu not only the situation is involved but also place, person and even a word could not be recognized. It is associated with aphasia, amnesia and epilepsy.
Another one is Presque vu is again a French word known as "almost seen". It is a situation when someone cannot recall a familiar word or name, but with effort one eventually recalls the elusive memory. In simple words, it is occurred before, but the details are elusive because the situation never happened before. It is also called tip of the tongue because when one is experiencing the Presque vu they say it is almost on my tip of tongue.
Other include Reja vu, which is something which is already happening, tends to make feel that it will happen again, in near or distant future.
There is one more to a related phenomena which is Deja entendu which is in French "already heard", it is interesting that it gives a feeling of surety that person has already heard the thing, even though it can be imagined or assumed.
