The truth is that there are two actual, non-hallucinatory ghosts haunting Post 047’s wiggle room. No one knows whether there are any in the Immersive Pods; those Pods are worlds unto themselves.
The ghosts’ names are Garrity and Blumquist. Much of the following info comes after the fact from Claude Sylvanshine. Blumquist is a very bland, dull, efficient rote examiner who died at his desk unnoticed in 1980. Some of the older examiners actually worked with him in rotes in the 1970s. The other ghost is older. Meaning dating from an earlier historical period. Garrity had evidently been a line inspector for Mid West Mirror Works in the mid-twentieth century. His job was to examine each one of a certain model of decorative mirror that came off the final production line, for flaws. A flaw was usually a bubble or unevenness in the mirror’s aluminum backing that caused the reflected image to distend or distort in some way. Garrity had twenty seconds to check each mirror. Industrial psychology was a primitive discipline then, and there was little understanding of non-physical types of stress. In essence, Garrity sat on a stool next to a slow-moving belt and moved his upper body in a complex system of squares and butterfly shapes, examining his face’s reflection at very close range. He did this three times a minute, 1,440 times per day, 356 days a year, for eighteen years. Toward the end he evidently moved his body in the complex inspectorial system of squares and butterfly shapes even when he was off-duty and there were no mirrors around. In 1964 or 1965 he had apparently hanged himself from a steam pipe in what is now the north hallway off the REC Annex’s wiggle room. Among the staff at 047, only Claude Sylvanshine knows anything detailed about Garrity, whom he’s never actually seen—and then most of what Sylvanshine gets is repetitive data on Garrity’s weight, belt size, the topology of optical flaws, and the number of strokes it takes to shave with your eyes closed. Garrity is the easier of the wiggle room’s two ghosts to mistake for a phantom because he’s extremely chatty and distracting and thus is often taken by wigglers straining to maintain concentration as the yammering mind-monkey of their own personality’s dark, self-destructive side.
Blumquist is different. When Blumquist manifests in the air near an examiner, he just basically sits with you. Silently, without moving. Only a slight translucence about Blumquist and his chair betrays anything untoward. He’s no bother. It’s not like he stares at you in an uncomfortable way. You get the sense that he just likes to be there. The sense is ever so slightly sad. He has a high forehead and mild eyes made large by his glasses. Sometimes he’s hatted; sometimes he holds the hat by the brim as he sits. Except for those examiners who spasm out at any sort of visitation—and these are the rigid, fragile ones who are ripe for phantom-visits anyhow, so it’s something of a vicious circle—except for these, most examiners accept or even like a visit from Blumquist. He has a few he seems to favor, but he is quite democratic. The wigglers find him companionable. But no one ever speaks of him.
