"Did I ever tell you... the definition of insanity?"

— Vaas Montenegro, Far Cry 3

Any tropes involving madness or insanity. Except those dealing with Hollywood Psych.

These can run the gamut from the weird but generally happy chaos that inhabits the Cloudcuckoolander's mind to the darkest corners of a person's shattered psyche.

Categories:

Please sort tropes appropriately. Some tropes may fit in both the 'Characters' index and the 'Madnesses' index, but each trope should only belong in one section of each index.
