Monothematic Delusions

Capgras delusion: the belief that (usually) a close relative or spouse has been replaced by an identical-looking impostor.

Fregoli delusion
: the belief that various people who the believer meets are actually the same person in disguise.

Intermetamorphosis
: the belief that people in one's environment swap identities with each other whilst maintaining the same appearance.

I like it. I've been thinking about ghosts lately. And these definitions remind me of several Ingmar Bergman films.

these delusions address the discrepancy between the lack of emotional response elicited by the presence of another, and the expected (required) response (a disruption that is often caused by a trauma or brain injury). "I recognize you as my lover, but feel no love for you, therefore you must have changed, must be an impostor." We project our emotional response onto people as the basis of their identities.
