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, bipolar disorder (during the elevated stages of mania), narcissistic personality disorder, and schizotypal personality disorder, and even autism when under periods of intense stress. To a lesser extent, it can be a hallmark of paranoid personality disorder as well as body dysmorphic disorder. Such symptoms can also be caused by intoxication, such as from stimulants like methamphetamine.
