Is there a way to determine dreams?

i keep having dreams about this one guy. like ever night. and i cant stop myself cuz its my subconscious. so does this mean anything? cuz i really like him and he seems to be interested in me...or thats waht my freind tells me. but why do i keep dreaming about him? in my dreams, i even "predicted"what was going to happen with him the next day. and it came true. what does this mean?
