There is a delusion named after the Truman Show

Psychiatrists have recently documented a new type of delusion: The Truman Show Delusion. This is a belief that a person is living inside of a reality TV show where they are the star and everyone around them are backup actors. While it is normally fairly harmless, it is a bit scary that people are finding it harder and harder to differentiate between reality and fiction. It is named after the film The Truman Show, which finds Jim Carrey as the main character in a show he does not know exists.
