Megalomania

Megalomania (from the Greek word μεγαλομανία) is a psychopathological condition characterized by delusional fantasies of wealth, power, genius, or omnipotence - often generally termed as delusions of grandeur. The word is a collaboration of the word "mania" meaning madness and the Greek "megalo" meaning an obsession with grandiosity and extravagance, a common symptom of megalomania. It is often symptomatic of manic or paranoid disorders.
