Deja vecu(already experienced or lived through)

We have all some experience of a feeling, that comes over us occasionally, of what we are saying and doing having been said and done before, at another time - of our having been surrounded, by the same faces, objects, and/or circumstances where we knew perfectly what would be said next, as if we were suddenly remembering it! This describes the feeling that many people know as deja vu. It is estimated that about one third of the general population have had such or similar experiences.
