The belief that one is the main character in a simulated or fictional world, and that everyone else is merely an NPC (non-player character) or a bot, is a phenomenon sometimes referred to as "Truman Show delusion" or "Truman Syndrome." This term is inspired by the movie "The Truman Show" (1998), in which the main character, Truman Burbank, lives in a constructed reality unknowingly and is the central figure of a reality TV show.
Truman Show delusion is not officially recognized as a distinct mental disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM) or other classification systems. However, it can be seen as a manifestation of a broader psychological condition known as a delusional disorder.
A delusional disorder involves holding false beliefs that persist despite evidence to the contrary. These beliefs are not culturally or socially accepted and significantly impact the individual's daily life and functioning. When someone genuinely believes they are the main character and others are mere NPCs or bots in their personal simulation, it may indicate a form of delusional disorder.
It is essential to note that delusional disorders are relatively rare, and not everyone who experiences similar thoughts necessarily has a mental disorder. Sometimes, such beliefs could be influenced by other factors, such as philosophical or existential contemplations, rather than indicating a psychological condition.
If someone is experiencing persistent and distressing beliefs about being the main character in a simulated world, it is crucial for them to seek professional help from a mental health professional, such as a psychiatrist or psychologist, for proper evaluation and potential treatment. Treatment approaches may include cognitive-behavioral therapy, medication, or a combination of interventions depending on the individual's specific situation and needs.
