usually people say it's your uncounscious mind working, and that dreams are just dreams, a process of evacuating disturbing thoughts or something like that. it's hard to say if your dream has a meaning or not, there is no simple answer. can you relate it to something happening in your life? has one of your friends became pregnant and/or married lately? maybe it's your mind telling you your deep desire to become pregnant and get married, or maybe it's telling you will or it's a possibility.
in my case, sometimes, my dreams are really vivid, as if my mind was really at that place whatever it is, but people's faces always remain hidden in mists. i cannot tell if it's my mind making up some stories from the many books i've read, or if it's something real. when i wake up with the feeling of bitter, utter failure, i tend to think those dreams have a meaning though i cannot grasp its content.
sometimes, details of my dreams become true in a totally different scene of my daily life. creepy, thank goodness it happens not so often.
