Nothing to worry about. You've had a couple of prophetic dreams, which every one has from time to time. If not you put so much energy into thinking about something that you manifested it.
Oh, but about that Deja Vu, if it happens frequently like a couple of times a day, I would suggest that you drop by at a neurologist just to check if everything is ok. Studies have shown that frequent deja vu signals the possibility of epilepsy. However, if it doesn't happen that frequently, I wouldnt worry about it.
On the spiritual front, I think you're doing just fine.
