Deja vu: Has it happen to you?

I read in a book once thatthis is a recollection of something we are shown before we are born of a preview of our life...it touched on that we are shown a type of movie and when we get this feeling of something happening before is actually remembering something we saw and then at the end of our lives we are shown a review of our lives as I guess everyone has heard how our lives flash before us...maybe there is many things we don't understand as we really are closed minded about certain things.
