The Difference Between Hallucinations and Delusions

2. Common Types of Delusions

Delusions typically fall into one of two categories: Delusions of grandeur or grandiosity: the person thinks they are more important, powerful, or omnipotent than they really are. For example, they may claim to be related to a famous celebrity, believe they can read minds or predict they will be elected President one day because of their intelligence. Delusions of persecution: if someone believes another person or organization is stalking, spying on, or watching them for nefarious reasons, they may have paranoid delusion disorder. Delusions can sometimes be extremely bizarre, such as a person believing a visitor from another planet has removed their internal organs and replaced them with alien parts.
