meaning of dreams pregnant

in my dream Im pregnant and Im living in a really pretty area very colorful and next thing I know, the place is now ruins and its real the sky is gray and its just me and a little 3 year old boy and Im holding his hand (this is my son in the dream years later) and i look back at him and smile and i tell him everythings okay....when i woke up that morning i started to cry because I missed my little boy in my dream. I have my theories but nothing that really seems right.
