Dreams that seem to predict the future are known as precognitive dreams. They're one of those things where some people believe in them and others don't. Personally, I don't and just think they're funny coincidents. For example one night I dreamt of making a peanut butter ice cream sundae. Later that next day my mom brought home peanut butter ice cream for some reason saying, "I was in the mood." I thought it was a little humorous that I had had a dream prior to this predicting it but I don't believe dreams to be future tellers. However you're free to believe in that and I encourage you to look into it if you're curious but don't believe it completely without at least putting some thought into it.
