I think its pretty obvious that this song is about a long distance relationship. The narrator has a significant other whom he misses and loves, but the narrator finds it extremely difficult, the relationship that is, for several reasons. For example, the long distance bills, the fact that he wakes up with his pillow in his arms (which he wishes was her) and the fact that he's dreaming of sex rather than actually having it with her.
