Dream of mother

I am having this same repeated dream about 2 or 3 times a month of a friend of mine that is a man. I've known him for many years since we was in elementary school. Now I'm 26. I only like him as a friend. But in my dream his mother was telling me "I'm so grateful that you are with my son, you changed him to the better and I'm so lucky to call you my daughter-in-law". Also in my dream, me and her son had 2 daughters and they were running around playing. Any clue of what this dream is meaning? Is it some type of vision or is God trying to tell me something?
