Grandiose delusions or delusions of grandeur are a type of delusion characterized by fantastical beliefs that one is famous, omnipotent, or otherwise very powerful. In psychiatry, this is a diagnostic criterion for psychotic disorders such as schizophrenia or bipolar mania. Delusions of grandeur are generally fantastic, often with a supernatural, science-fictional, or religious bent (for example, belief that one is an incarnation of Jesus Christ). Delusions of grandeur are distinct from megalomania or narcissism, in that the sufferer does not have insight into his loss of touch with reality.
In colloquial usage, one who is said to have 'delusions of grandeur' is considered to be one who overestimates ones own abilities, talents or situation. This is generally due to excessive pride, rather than any actual delusions.
