I don't know, but I had an intimate dream about a guy (not sex though) and the next time I saw him it felt like he knew. It was very strange. Anyway, I didn't dare mention it because I am happily married and I think it would have been asking for trouble. If you and this other person are single then I think that's sweet and I hope that something really good comes of it. If either of you is taken then just write it in your journal and move on. :) Best wishes!
ETA: I just went back and looked at your question for 1.29.12... During that time you asked if there is a way to have a girl... Soooo, now I am thinking that the baby girl in your dream represents your desire to have a little girl and this guy in the dream must be someone you think is cute or something. Again I say, if either of you are taken then just let it go. :)
BTW: I do believe there is a way to influence the gender of your children. I don't know the stats for it, but we successfully conceived the desired gender with our first 2 (we didn't try it the 3rd time and we had twin girls-- who I dreamed of 2 years before they were born :) ). Also, I know people, two of them in the last year who successfully conceived the desired gender. It was a matter of having sex on certain days. HTH. OH AAAAAAND: I remembered that once me and my husband had the same dream and when I was a kid me and my grandma had the same dream. (Both times it was the same night.)
