There's a room that's full of emptiness Since you walked out the door Leaving me with only city lights Sleeping blue nights Dreaming shadows of what used to be Like we were once before And I'm thinking was I wrong or right Now you're out of sight I'm sleeping blue nights Why... Did you have to go Boy I want to know Why... Did you take away All my yesterdays Leaving me Sleeping blue nights Sleeping blue nights All I ever do is think of you What I'm going through Sleeping blue nights Cry... Is all I seem to do But it get's me through Cry... Until my eyes run dry Won't you tell me why Sleeping blue nights Sleeping blue nights All I ever do is think of you What I'm going through Sleeping blue nights Sleeping blue nights
