Those are some interesting thoughts, and it's really interesting to me that you're experiencing premonitions. As far as truth to all of this, I have no ideas. But I've heard about people having prophetic dreams before and I'm inclined to believe in it, at least a little.

Thing is you'll have to just decide for yourself what you believe, you've been able to validate a couple things which is pretty interesting, so test more things and see what you find. I think it's entirely possible that you're having prophetic dreams. Why not?

I'd suggest reading "The Interpretation of Dreams" by Freud. It might help you draw some conclusions and rule out other possibilities for what your dreams might mean.
