What is "déjà vu"?


Poseidon

Recommended Posts

The term deja vu is French and means, literally, "already seen". Those who have experienced the feeling describe it as an overwhelming sense of familiarity with something that shouldn't be familiar at all. Say, for example you are traveling to England for the first time. You are touring a cathedral, and suddenly it seems as if you have been in that very spot before. Or maybe you are having dinner with a group of friends, discussing some current political topic, and you have the feeling that you've already experienced this very thing -- same friends, same dinner, same topic.

 

The phenomenon is rather complex, and there are many different theories as to why deja vu happens. Swiss scholar Arthur Funkhouser suggests that there are several "deja experiences" and asserts that in order to better study the phenomenon, the nuances between the experiences need to be noted. In the examples mentioned above, Funkhouser would describe the first incidence as deja visite ("already visited") and the second as deja vecu ("already experienced or lived through").

 

As much as 70 percent of the population reports having experienced some form of deja vu. A higher number of incidents occurs in people 15 to 25 years old than in any other age group.

 

Deja vu has been firmly associated with temporal-lobe epilepsy. Reportedly, deja vu can occur just prior to a temporal lobe seizure. People suffering a seizure of this kind can experience deja vu during the actual seizure activity or in the moments between convulsions.

 

Since deja vu occurs in individuals with and without a medical condition, there is much speculation as to how and why this phenomenon happens.  Several psychoanalysts attribute deja vu to simple fantasy or wish fulfillment, while some psychiatrists ascribe it to a mismatching in the brain that causes the brain to mistake the present for the past.Many parapsychologists believe it is related to a past-life experience.Obviously, there is more invesgation to be done.

My mother used to tell me that if I experience déjà vu, it means that I'm on 'the right path' in life - as if it were an unknown outline I'm following.

 

Another theory I heard is when a person experiences déjà vu, it means that you're experiencing the same phenomenon that a person in your past life also experienced.

But, of course, that's only if you believe in reincarnation.

Might sound stupid, but sometimes I dream about doing a certain thing and then do it actually later.

 

Just one of the most stupid examples that I can recall:

I was asleep and dreaming i played Wolfenstein:ET on goldrush, after exiting the allied second spawn after repairing the tank i can see a smokescreen from a smokegrenade near the commandpost.

Behind this smokescreen an axis medic shooting at an allied soldier, I tracked the muzzleflash of the axis medic shooting and shot and killed him.

 

a couple of months later i actually did it exactly the way i remembered from my dream.

This doesnt happen often but when it does i will forget it but when it happens i will remember that i dreamt it earlier or just feel that it is way too familiar.
