I had a dream about my friend...?

I had a dream about my friend last night, i dreamt that her, me and her daughter were takin a train to new york, actually ellis island. ( we live in nj) and we were half walf way there and the people wouldn't let my friend back on the train because she was pregnant..she was really far along and she was carrying low. I called and told her when I woke up and she said she has a date tonight. Any idea as to what this means?
