The Old Curiosity Shop by Charles Dickens

Tossing to and fro upon his hot, uneasy bed; tormented by a fierce thirst which nothing could appease; unable to find, in any change of posture, a moment's peace or ease; and rambling, ever, through deserts of thought where there was no resting-place, no sight or sound suggestive of refreshment or repose, nothing but a dull eternal weariness, with no change but the restless shiftings of his miserable body, and the weary wandering of his mind, constant still to one ever-present anxiety--to a sense of something left undone, of some fearful obstacle to be surmounted, of some carking care that would not be driven away, and which haunted the distempered brain, now in this form, now in that, always shadowy and dim, but recognisable for the same phantom in every shape it took: darkening every vision like an evil conscience, and making slumber horrible--in these slow tortures of his dread disease, the unfortunate Richard lay wasting and consuming inch by inch, until, at last, when he seemed to fight and struggle to rise up, and to be held down by devils, he sank into a deep sleep, and dreamed no more.

He awoke. With a sensation of most blissful rest, better than sleep itself, he began gradually to remember something of these sufferings, and to think what a long night it had been, and whether he had not been delirious twice or thrice. Happening, in the midst of these cogitations, to raise his hand, he was astonished to find how heavy it seemed, and yet how thin and light it really was. Still, he felt indifferent and happy; and having no curiosity to pursue the subject, remained in the same waking slumber until his attention was attracted by a cough. This made him doubt whether he had locked his door last night, and feel a little surprised at having a companion in the room.
