Deja Vu Feeling

Do you guys ever get that crazy Deja Vu feeling? Like...where you feel like you've done something before, but you really haven't?
Ever since I was like, nine, I always kinda wondered: What if, when we're either about to be born or we're babies, we have these dreams where we see our entire life?? I know I sound crazy, I know... but what if you really do?! And then when you do something... it just suddenly hits you that you KNEW this was coming?!?!?!

Today I just had the weirdest thing. I was just thinking about random things, having major brainfarts, the usual. Then, all of a sudden, I thought of my PE track. And then it hit me. It freaking hit me. I had a dream like this once. I was walking through the rocks, with my friends, who's faces were blurred since I had no idea who they were at the time, whenever the time was that I had this dream.
The sides of the dream were blurred, and I could barely see anything. But I remember. I remember looking at the red track and up at my PE teacher, who's face was also blurred. I just saw her whistle. and then I woke up.

Scary.
You guys ever experience something like this??
