deja vu

this is a great example of how science has tried to 'explain' past knowledge and experience. Here are the two sides of the coin:

• the experience of feeling sure that one has witnessed or experienced a new situation previously (an individual feels as though an event has already happened or has happened in the recent past), although the exact circumstances of the previous encounter are uncertain. 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. The experience of déjà vu is usually accompanied by a compelling sense of familiarity, and also a sense of "eeriness," "strangeness," "weirdness," or what Sigmund Freud calls "the uncanny." The "previous" experience is most frequently attributed to a dream, although in some cases there is a firm sense that the experience has genuinely happened in the past. The experience of déjà vu seems to be quite common among adults and children alike.

And then there is:

• Scientifically speaking, the most likely explanation of déjà vu is not that it is an act of "precognition" or "prophecy," but rather that it is an anomaly of memory, giving the impression that an experience is "being recalled." and.... encountering something which evokes the implicit associations of an experience or sensation that cannot be remembered may lead to déjà vu.

Hmmm, what science always fails to account for are the 'feelings' associated with deja vu. That absolute innate knowing that something has indeed been experienced before, a person has been met before, something has been said before.......
