I would like to know if there is any meaning in my dream or am i reading too much into it

There's this guy that is constantly coming up in my dreams. I don't know him personally, I've seen/met him at clubs maybe about 10 times in a 2 year space, &we've spoken,nothing more. I haven't seen him since earlier last year. I know I'm extremely attracted to him, but i also know he has recently moved to another country, so i won't be seeing him again anytime soon... In my dreams I'm in a committed happy relationship with him, having more kids... i don't even know him... I dont think of him until i have these dreams, which is at least once a week and then i can't get him out of my head.. why am i constantly dreaming of him? Can anyone help please?
