This dream shows that you don't have a stable partner yet, but you want to form a family with someone in your heart. Of course, because you dream of a child, you just want to have a family, so you don't have a specific concept of what a child will look like! Is a very vague concept!
I suggest you look at Freud, although he is different from Duke Zhou, but if you read it carefully, some dreams can be explained by his theory.
