The thing with Deja Vu with when it happens to me is that I experience the exact same thing i've experienced before and precisely facing doing or moving in the same precise way I did in a past experience. Then after a sec the feeling all disappears and i'm like. this happened before but its like you forgot when or where it happened. I think it's a little paranormal if you ask me. as if there were invisible wavelengths in the air and they matched with recorded or stored brainwaves that you've had with the past experience...im not making any sense am I . lol!
