Have you experienced déjà vu?

According to Wikipedia,

Déjà vu is 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 near past).

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.

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; it is the impression that an experience is "being recalled".

Another theory being explored is that of vision. As the theory suggests, one eye may record what is seen fractionally faster than the other, creating that "strong recollection" sensation upon the "same" scene being viewed milliseconds later by the opposite eye.

Some believe déjà vu is the memory of dreams. Though the majority of dreams are never remembered, a dreaming person can display activity in the areas of the brain that process long-term memory. It has been speculated that dreams read directly into long-term memory, bypassing short-term memory entirely. In this case, déjà vu might be a memory of a forgotten dream with elements in common with the current waking experience. This may be similar to another phenomenon known as déjà rêvé, or "already dreamed."

I've always experienced déjà vu in my entire life, every single day - walking up the stairs, running down the slope, flipping through books, talking to someone, looking at someone, etc. It's the feeling that keeps me wondering and wondering for some time. Never had I gotten a reasonable answer. Somehow, I got used to this feeling, this really amazing feeling, already.

Omg even typing this post makes me have déjà vu!
