I don't think I've ever had a precognitive dream like you describe. However, I've had some dreams that seemed to uncover things I had missed when I was waking that later seemed true when I thought about them. Also, I had a recurring dream when I was a child that I later uncovered in a photo my parents had. i..e. it was something that really happened, but I didn't remember it consciously. Dreams are weird, no doubt. :)
