Dream of married

Last night I dreamt the girl I'm in love with was getting married but she's 18 and I was running after her as she was walking up to the altar to tell her how I feel but everyone was in front of me trying to get to their seats and by the time I looked she was at the top and had to sit and watch them get married but I couldn't see her at the altar. When she was walking out everyone was clapping and by the time she passed me it wasn't her, it was a different girl.
