Claude, in the state of hallucination in which he found himself, thought he was seeing with his living eyes the steeple of hell; the countless lights distributed along the whole height of the horrifying tower appeared to him like so many openings into the huge inner furnaces; the voices and murmurs coming from it, like so many cries, so many death-rattles. Then he felt afraid, he put his hands over his ears so that he should hear no more, turned his back so that he should see no more, and strode away from the fearful vision.
Frodo Baggins in "The Lord of the Rings":
"No taste of food, no feel of water, no sound of wind, no memory of tree or grass or flower, no image of moon or star are left to me. I am naked in the dark, Sam, and there is no veil between me and the wheel of fire. I begin to see it even with my waking eyes, and all else fades."
