Je l'ai deja vu

I had a bit of a deja vu while on the phone with a friend this morning, so I thought I'd have a peek around the world wide web and see what was up with that. I like the explanation that says your cognition is lagging behind your perception, creating the feeling that you are experiencing and recalling the event at the same time. It's pretty neat, however you look at the phenomenon. The whole thing has, as the French said and we English speaking types have come to say, a certain je ne sais quoi.
