This is all I got (From wikipedia):
Paranoia is an excessive anxiety or fear concerning one's own well-being which is considered irrational and excessive, perhaps to the point of being a psychosis. This typically includes persecutory beliefs concerning a likely threat, or a belief in a conspiracy theory. In the original Greek, παράνοια (paranoia) means simply madness (para = outside; nous = mind) and it is this use which was traditionally used in psychiatry to describe any delusional state. However, the exact use of the term has changed over time in medicine, and because of this, modern psychiatric usage may vary.
In popular culture paranoia is often represented as including:
* Belief in having special powers or being on a special mission (a "delusion of grandeur")

* Black helicopters and other mass surveillance
* Persecution from powerful adversaries such as UFOs, terrorists, the Men in Black, secret societies or demons
* Paranoia or belief in conspiracy theories involving perceived political or social enemies (as in The Paranoid Style in American Politics by Richard Hofstadter)
* Mind control through invisible rays, and tinfoil hats to combat them
* Fear of poisoning, adulterated food (e.g., aspartame) or water (e.g., fluoridation) as part of a secret plot
* Reading a story, watching a movie, or listening to a song and feeling that one's life is exactly like that of the subject of said story, movie, or song. The movie The Truman Show, which depicted a man who discovers his entire life has been filmed as a TV show, is one of the more commonly referenced films.
* The maxim: Just because you're paranoid doesn't mean that they aren't really out to get you.
* Along the same vein: Even paranoids have enemies.
