So true indeed. Paranoia dovetailed with Narcissistic Personality Disorder is nasty, nasty combination:
"The paranoid delusions of the narcissist are always grandiose, "cosmic", or "historical". His pursuers are influential and formidable. They are after his unique possessions, out to exploit his expertise and special traits, or to force him to abstain and refrain from certain actions. The narcissist feels that he is at the centre of intrigues and conspiracies of colossal magnitudes. Alternatively, the narcissist feels victimized by mediocre bureaucrats and intellectual dwarves who consistently fail to appreciate his outstanding - really, unparalleled - talents, skills, and accomplishments. Being haunted by his challenged inferiors substantiates the narcissist's comparative superiority. Driven by pathological envy, these pygmies collude to defraud him, badger him, deny him his due, denigrate, isolate, and ignore him.
The narcissist projects onto this second class of lesser persecutors his own deleterious emotions and transformed aggression: hatred, rage, and seething jealousy.
The narcissist's paranoid streak is likeliest to erupt when he lacks narcissistic supply. The regulation of his labile sense of self-worth is dependent upon external stimuli - adoration, adulation, affirmation, applause, notoriety, fame, infamy, and, in general, attention of any kind.
When such attention is deficient, the narcissist compensates by confabulating. He constructs ungrounded narratives in which he is the protagonist and uses them to force his human environment into
Put simply, he provokes people to pay attention to him by misbehaving or behaving oddly."
