I read this one probably something over forty years ago, in a collection. I do not remember title of the story or the collection, and I do not recall the author. I think it may have originally have appeared in "Playboy", but I don't know. F&SF would also be a likely place.
The initial hook was a line from a "therapist", not the viewpoint character, about having a drawerful of girls that needed attention. The viewpoint character immediately envisioned shallow drawers, with very miniature women, and a sign saying something like "You are the property of ...". The drawer turned out to be a file cabinet drawer, in a file cabinet, described as large enough for an adult woman if she bent double.
The "girls" were described as "ghosts". Each was a psychological "snapshot", extracted somehow from a patient. The theory was that removing that "ghost" would remove certain bad feelings or beliefs.
The plot involved one of the patients breaking in, to reclaim her five "ghosts" and have her revenge on the "therapist".
Interesting tidbits: To keep the viewpoint character quiet, the therapist wrapped him in an interesting self-clinging plastic sheet. The sheet was full of tiny valves, that would allow slow respiration, but close completely if the person tried to take a deep rapid breath (e.g., to scream). The break-in used another kind of plastic: it clung, fully elastic, until electrified, when it became VERY stiff and pushed back on things pushed in while it was elastic. The patient used this to defeat the office door locks.
The most interesting bit was a musical piece, entitled "Ghost Girls Pavane". The viewpoint character described it as sounding like it came from "The Nutcracker", but not from any version he'd ever heard. The "therapist" said it was in fact a movement from "The Nutcracker", that had been highly controversial, so much so that it was suppressed.
