Ideas and delusions of reference
Ideas of reference and delusions of reference describe the phenomenon of an individual experiencing innocuous events or mere coincidences and believing they have strong personal significance. It is "the notion that everything one perceives in the world relates to one's own destiny", usually in a negative and hostile manner.
In psychiatry, delusions of reference form part of the diagnostic criteria for psychotic illnesses such as schizophrenia, delusional disorder, and bipolar disorder with mania, as well as for the narcissistic and schizotypal types of personality disorder. To a lesser extent, their presence can be a hallmark of paranoid personality disorder, as well as body dysmorphic disorder. They can be found in autism during periods of intense stress. They can also be caused by intoxication, such as from stimulants like methamphetamine.
