Why do I have so many Premonitions?

I think I'm going a crazy. I've been having a lot of premonitions lately. While I'm dreaming, my dreams feel like there so real. I wake up remebering the whole dream. The next day that very same dream happens. Like in one of my dreams I was riding my dirtbike and did a backflip hit my head on a small pine tree I've never seen before. The next day the very same thing happened and now I've seen that pine tree!! Please TELL ME THIS NORMAL!! and I'm OKAY
