Today I have fallen down the wiki hole of Monothematic Delusions

‘People who experience these delusions as a result of organic dysfunction often do not have any obvious intellectual deficiency nor do they have any other symptoms. Additionally, a few of these people even have some awareness that their beliefs are bizarre, yet they cannot be persuaded that their beliefs are false’

Capgras delusion: the belief that (usually) a close relative or spouse has been replaced by an identical-looking impostor.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 whom the believer meets are actually the same person in disguise.

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

Subjective doubles: a person believes there is a doppelgänger or double of him- or herself carrying out independent actions.

Cotard delusion: the belief that oneself is dead or does not exist; sometimes coupled with the belief that one is putrefying or missing internal organs.

Mirrored-self misidentification: the belief that one's reflection in a mirror is some other person.

Reduplicative paramnesia: the belief that a familiar person, place, object, or body part has been duplicated. For example, a person may believe that they are, in fact, not in the hospital to which they were admitted, but in an identical-looking hospital in a different part of the country.

Somatoparaphrenia: the delusion where one denies ownership of a limb or an entire side of one's body (often connected with stroke).
