I thought Deja-Vu was when you feel like you've done the thing you are currently doing before when you never have. The first time I went to Disney World, I felt really strongly like it seemed so familiar and like I'd been there before but I never had.In fact, 5000+ miles away (in U.K.) while talking to a friend
of mine (we're all like one big family) - just spooked her out
when they didn't like the movie they were watching and all of
a sudden I just lapsed into a Déjà Vu and said "Independence
Day!" - and that was exactly what the Uncle had picked out
and inserted into the Blu-Ray player.
