I get déjà vu friggin' all the time. I have loads of dreams that end up happening later on. Not necessarily every part of it, but about three minutes of the dream and what happened in real life will be the same. It's always like, a year or so before it happens in real life, too. Thankfully, they don't end the same, because that would be freaky. Most of the dreams that I have déjà vu with end with some kind of small disaster (hence making my dreams ultra-cool, but would make real life ultra-whack), so when I get hit with it, I look around for whatever small disaster happened in my dream hastily, then continue on with whatever I was doing. Although, not gonna lie, there is the occasional dream that would be super-awesome if it happened the same in real life.
