World's End by Richard Jefferies

After a while, Aymer awoke from the stupor into which the drug that had been administered to him had thrown his senses. His awakening was more painful than the first effects of the poison. His head felt as heavy as lead, and there was a dull pain across his brow.

Then all the designs upon the wallpapering got mixed up before his eyes in a fantastic dance, which made him giddy, till he was obliged to shut them. His consciousness had as yet barely sufficiently returned for him to notice that he was in a different apartment to any he had hitherto occupied at the asylum. He must have had partial returns to consciousness previously, for he found himself sitting in a large armchair, half clad, and wearing a dressing-gown. A second pull at the bell-rope brought footsteps outside the door, which sounded heavy upon the boards, evidently uncarpeted.
