dreaming is the cause of dejavu?
http://science.howstuffworks.com/deja-vu5.htm
I suppose everyone has precognitive dreams, whether they remember them or not. But even if you can't remember them upon awakening, they're still there stuck somewhere in your subconcious. Which is why the dejavu feeling is so strange. Because you have no idea where you remembered that experience from. It's like you've just remembered it from your subconcious. So isn't dejavu just a memory of a precognitive dream that you didn't remember after waking up? Why dont all scientists believe that this is the cause? what other explination is there?
