Deja vu is because you have about a million dreams a night and so you see endless outcomes and situations. Over the course of time, it's only natural that you'll have something line up similarly to one dream. I've also heard it theorized that during a lot of deja vu, you're just identifying events with non-specific things that happened in your dream causing a feeling of deja vu.
