i have deja vu many times a day. i'd be just sitting there and then all of a sudden realize that i've already seen what is going on and i know what is about to happen. i feel as if i'm living a life that's already been lived. is this possible? am i going crazy?
Deja vu is where you think it's alreay happened because of like 4getmenot said, brain wires getting crossed, it tricks you into thinking you've seen it before.
