waida gave me an interesting comment on friendster about déjà vu.. so, i went into research mode and went online to read up on this weird phenomenon. so here it is..
the term déjà vu is french and means, literally, "already seen." there are many different theories as to why déjà vu happens. as much as 70 percent of the population reports having experienced some form of déjà vu. a higher number of incidents occurs in people 15 to 25 years old than in any other age group.
déjà vu has been firmly associated with temporal-lobe epilepsy. reportedly, déjà vu can occur just prior to a temporal-lobe epileptic attack. people suffering an epileptic seizure of this kind can experience déjà vu during the actual seizure activity or in the moments between convulsions.
since déjà 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 déjà 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. as you can see, there are many theories to déjà vu. even though one interesing theory is related to past-life, i on the other hand, am a man of logic. this is why i believe in aliens but not in ghosts or spiritual phenomenons. but these are another topic for another day..anyway, i shall expand on the brain theory.
this involves a glitch in the exquisitely timed processes of perception and cognition. this theory proposes that sensory impressions of a current experience get detoured in the brain and are not immediately perceived. the information is, however, stored as a memory. this split-second delay in cognition creates the unsettling impression that the event is being experienced and recalled simultaneously. to put it simply, the brain screwed up. the new experience was suppose to be put in the 'new items' but mistakenly put in the 'old items'. suddenly, you instantly recall the similar 'past memory' that was mistakenly put in. and that's why we think we've seen or done it before.
whether it's a slip up of the brain, a past life experience or something else entirely, déjà vu will remain one of the mind's most tantalizing and elusive tricks.
