What does this dream mean when the guy became a reality? (Please read)?

I'm 15 and I had a dream that I was a few years older and I was at my wedding and the groom was a tall boy my age with black flippy hair (lol) and bright blue eyes and he was tan with 1 piercing in 1 ear. Someone was talking to him and said his name was Trey (This was saturday) My friend went to church but I wasnt there this week anyways they said there's a new kid with the same name and appearance and everything. I have never met him before. Help?!
