Gately mute in the Trauma Wing (p. 817)
The blinds were up, and the room was so bright-white in the sunlight everything looked bleached and boiled. The guy with either the square head or the box on his head had been taken off someplace, his bed unmade and one crib-railing down. There were no ghostish figures or figures in mist. The hallway was no brighter than the room, and Gately couldn’t see any shadows of anybody in a hat. He didn’t even know if last night had been real.
Context
Morning after the tornado fever-dream: daylight empties the room of ghostish figures and hat-shadows, and Gately explicitly can't rule on whether the night was real. The line does the theme's characteristic work — it refuses to file the haunting under hallucination, leaving "real" an open question the wraith-scene will answer.
