Joelle's teeth and the dentist dream — "His bib hangs by a necklace…"
His bib hangs by a necklace of tiny steel balls and could not be whiter, his head haloed with a strap and a polished metal disk attached to the strap just above his eyes, a tiny mirror of stainless steel, clean as the instruments’ tray; and the dream’s yielding and trustful quality of calm is undercut only by the view of her face in the halo’s mirror, the disk like a third eye in Gately’s broad clean forehead: because she can see her face, convexly distorted and ravaged by years of cocaine and not caring, her face all bug-eyes and sunken cheeks, lampblack-smudges beneath the pop-eyes
Context
The dream's optics assembled with real precision: the "haloed" strap (halation vocabulary riding the mirror), the disk "like a third eye," and — decisive — the mirror is convex, so distortion is built into the instrument. Whether the ravage is her face or the disk's curvature the dream never adjudicates, which is the whole U.H.I.D. question in one image: the veiled woman forced to spectate on her own spectation. (Kinship with the Entertainment's own apparatus — a distorting device aimed at a face, the auto-wobble lens of 062/178 — recorded as inference only. Note the plan's one-liner says "built of lenses"; the raw's apparatus is strictly the mirror-disk and dental instruments, no literal lens — see Flags.)
