If you dream about a guy, how can you know whether it’s a prediction about your future?

I’ve been looking at my dream diary and I realize that at least 3 of my dreams have given me advice about who to marry and what type of relationship I will have if we get together, I’ve been asking God to show me through signs who I’m going to marry and now I realize a lot of the answers are in my dreams. I used to think God did not want me with the guy I like cause I never dreamed about him and now I realize he has appeared in my dream through symbolic figures.
