The term used when two or more people share the same delusion is "Folie à deux." This concept, also known as shared psychotic disorder, describes a scenario where one person's psychotic beliefs are communicated to another individual, often due to a close relationship. This phenomenon typically occurs in situations where the individuals are socially isolated or share a significant emotional bond, allowing for the transmission of delusional ideas from one person to another.

In contrast, the other terms listed do not pertain to shared delusions. Trichotillomania refers to a hair-pulling disorder leading to hair loss, while conversion disorder involves neurological symptoms that cannot be attributed to medical conditions but are linked to psychological factors. Comorbid psychosis describes the presence of psychotic symptoms alongside other mental health disorders but does not specifically indicate shared delusions. Therefore, "Folie à deux" is the accurate term that specifically addresses the sharing of delusions between two or more individuals.
