The dreams continue...

so last night I had a strange dream (big surprise right?). I was still not looking pregnant but knew I was in labor. I wasn't really worried because for some reason even though I had only a small pooch, I knew I wasn't overly pre-mature. Labor was painless and fast. The baby was a boy ( I guess)... it was a cross between Curby and this little toy pig my cousin had back when I baby sat her. It was about 2 inches (smaller than my actual baby is now). Life went on and I named him Judah though some of my friends and family seemed surprised that I'd name this oddity what I'd planned to name my baby. My mom and dad were having an argument about something, some issue between the two of them, and off-handedly (sort of to get rid of me) told me it's normal, all babys look like that at first. When I nursed him or when he first woke up he would swell up like Curby right before he flys. Where does this shit come from? Someone please explain why pregnant women dream such odd things?
