The Great Divorce

by C.S. Lewis

I gasped when I saw them. Now that they were in the light, they were transparent—fully transparent when they stood between me and it, smudgy and imperfectly opaque when they stood in the shadow of some tree. They were in fact ghosts: man-shaped stains on the brightness of that air. One could attend to them or ignore them at will as you do with the dirt on a window pane. I noticed that the grass did not bend under their feet: even the dew drops were not disturbed. Then some re-adjustment of the mind or some focussing of my eyes took place, and I saw the whole phenomenon the other way round. The men were as they had always been; as all the men I had known had been perhaps. It was the light, the grass, the trees that were different; made of some different substance, so much solider than things in our country that men were ghosts by comparison.
