I think, its about a friend, who now is dead.
His life ways always on the fast track and meant everything to the writer.
The writer never had to worry about him, cause "he always found a way back home".
But then he died (Maybe The car accident friend of "Glass in the trees).
And suddenly a whole world broke down for the singer, he couldn´t realize it, because the friend was like a hero for him... The best die to fast....
So in the end he remembers when they were kids, he was sometimes helpless and his fiend helped him, so now he needs to sleep.
Maybe...
