Delusions of grandeur means having unrealistic beliefs about one's own importance, power, or abilities. It describes someone who thinks they are far more impressive or powerful than they really are.

The term comes from psychology, where it has long been used to describe a type of false belief in which a person imagines themselves to be extremely important, rich, or powerful.
