Dream of married

I dream that I am getting married, standing in my wedding dress. When I turn around I never see my grooms face. I had the same dream, only this time when I turned around expecting to see my fiancé, I turned to look at a man's chest. He was wearing a grey suit and when I looked up I saw his face this time, only didn't recognize him. A year later this stranger moved in next door to me. It took me quite a few months of trying to figure out where I recognized him from before realizing he was the man in my dream. What does it mean?
