The instrumental in this song shows longing, someone who's tired and wanting to forget someone he/she has fallen apart from. The lyrics tell us that the person wants to get some sleep due to feeling tired, and if they could, they would. However it's always about her/him when he/she dreams.
More than that, the song is about moving on. The person would be able to sleep, if only they could move on.
