What does this mean!

Robin
So I am a 21 year old who has never had the desire to have children. I have 2 little siblings (5 and 3) and they are PLENTY to deal with. I had a dream the other night however that my boyfriend and I had 2 boys about 2 or 3 years apart. One a newborn and one obviously about 3ish. And I have not been able to get this boy out of my head... I literally feel like a grieving mother. Give never felt like this before and all of the sudden I want that little boy so bad to the point where his face is stuck in my head. What does this mean?
