Pregnacy dreams

I have 5 more days to see if I get my period and I've been so hungry more than normal and I feel so full for longer even if I didn't eat that much. And I will still be hungry plus nipples sore anyways I had a dream last night I was in delivery room getting ready to give birth then I woke cause it felt so real it freaked me out. Has anyone had a dream you were pregnant and find out you were pregnant or have you dreamed being pregnant and not be? I'm just curious if it's just cause it's been in my mind so much.
