Answer 2

The term "déjà vu" (French for "already seen", also called paramnesia) describes the experience of feeling that one has witnessed or experienced a new situation previously.

The term was coined by a French psychic researcher, Émile 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 French concentrator at the University of Chicago.
The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eeriness", "strangeness", or "weirdness".
The "previous" experience is most frequently attributed to a dream, although in some cases there is a firm sense that the experience "genuinely happened" in the past.
Déjà vu has been described as "Remembering the future."

Answer 3

Here's the mechanics...

When you see someone, something, some place that you know, how do you know that you know it? That's long-term memory at work. When you see something, the short term memory does a "check" to see if the thing you are looking at is known to you. You look at your mom, your brain senses a pattern, and short-term memory checks with long term memory and tells you, yes, this is your mom. If the pattern is not recognized by long-term memory, it creates a new "file" and you realize that you are seeing something new. It's obvious that alzheimer's patients suffer a severe degradation of this process. Folks who are subject to epilepsy experience this

The more you see the same pattern, the more it get's "burned" into your long term memory, and neurons create shorter paths to access that knowledge. Consequently, the longer the length of time since you've seen something, further back along the neural path it get's pushed.

We're dealing with stuff that moves, literally, lightning fast, since neurons send electrical impusles along synapses.

So... what would happen if, somehow, a new person, a new place, or a new occurrance slips past the short-term memory and lands in long term memory before short-term memory has a chance to run the "check"?

In otherwords, you know that you're experiencing something new, but it's already in long term memory, so your short term check says aha! I've seen this before! But then you think - but I really never did see it before.... and hence you experience deja vu.

Answer 4

Deja vu is a french word that means "already seen." And that is exactly it.....we use it when we are in a strange place, but we "know" it, or when something happens, and we know we experienced it already.

Answer 5

everyone has a little power to see the future from dreams and dont' remember them. later they end up having to see it in real life. which can scare that person. or it's something that has happened in ur past life and is a repeat of what yo uare doing today. it's not like repeating ur life over just that having simlar stuff u did in ur past life.
