What do my recurring dreams about pregnancy mean?

I had a dream that I was pregnant, driving my husband to a bachelor party... We stopped to visit a family member and I remember sitting at a table. When I looked down I vividly remember seeing my belly and I was wearing this off white maternity sweater that I own. I also remember getting up and getting myself and my sister a glass of water and the dream... I am not currently pregnant but this dream was so vivid, I can't help but wonder what it means... I've been dreaming a lot about pregnancy ( recently I had a dream that I delivered a fat baby boy by myself, which was also very vivid, in addition to having another dream that I was pregnant in.. This was all in the last week or two). Anyone have any ideas???
