I think its about a soldier in a war that was left behind or got lost. And he is singing this song. And he says hes starting to dream in black and white because he is loosing the color of his life. As he is trying to find the way home he is spoted by the enemy and they are coming to get him. He gets pinned and eventually shot and is now completely seeing and dreaming in black and white. He is still firering back at the enemy. But they are coming closer and closer. They start sooting. And now he realizes it only hurts once. Even though the bullets are breaking his bones. He now tells himself that he has been holding on to tight. As he takes a few last bullets he lays back with his eyes open. And says out loud (as if the enemy would hear him) you will find me climbing to heaven. And as the breath of life leaves him. He smiles and closes his eyes. And leaves the world behind.
