Most of us have felt it before, that strange sensation that you’ve been somewhere or seen something before, as if you already remembered what’s happening. Are you psychic? Nope, that’s just déjà vu. Why does déjà vu happen? Well, scientists aren’t completely sure, but they’ve got a few good theories about it.
