That happens to me all the time too! It's crazy.

One that happens often is someone will say something to me and it will remind me of some really obscure movie or TV show I saw so long ago I'm not even sure if i really saw it or just made it up in my head, and later that day I'll flip on the TV and there it is.

Or I'll think of someone i haven't seen in ages and wonder how they are doing and then I'll bump into them later that day at the grocery store.
