Deja vu is life lag - when you see something, but because of high ping you see it twice

there are some idiotic bastard on here, deja vu occurs when the human brain uses exactly the same thought pattern twice, this often sparks the belief that u have done the momentary action before. also, when i get deja vu it makes me feel ill like nausea, its a type of epilepsy which can cause black outs.

a momentary infinitesimal lag in the operation of two co-active sensory nerve centers that commonly function simultaneously

Déjà vu is the really odd feeling you get when you see something happen the exact same way twice, or when you have done the exact same action before, and are doing it again. Usually the basis is completely improbable, like the other side of your mind is insisting that you could not have possibly seen the thing before.

Déjà vu is also a very kickass J-Pop song by Dave Rodgers.

As stated in the Sci Fi Series, Fringe (#3 in the list of Fringe), deja vu occurs when you have done something before, hence feeling you've done the same as what you're doing in your reality. In truth, you've done it, but in an alternate reality.

Ok heres what i think deja vu is. there are two possibilities.

1. Since humans only use about a quarter of our brain power we may be experiencing a sudden increase in our minds capabilities for a short moment resulting in a psychic remembrance of a current situation causing you too feel you have experienced it already.

2. There is a matrix and a glitch has occured. what happens is you experience a repeated situation then you say "didnt this happen already" and then the programmers of the matrix program your mind to say oh its just deja vu.
