I get dejavu pretty often.

Whats really weird though, is twice in my life, I've gotten it so strong, I knew what was going to happen next.
I was sitting in class one day back in highschool, talking to a group of people, and dejavu hit like a ton of bricks. I thought to myself... "that guys going to laugh and slap his forhead". 3 seconds later, the kid laughed and slapped his forhead.

another time I was with freinds and got hit with dejavu. I told them a cop car was going to pull around the corner in a second. again, few seconds later, a police car rounded the corner.

could have just been uncanny coincidences, but it freaked me out at the time.
