Insania

Insania is a latin word meaning many things, but mainly it means 'insanity', obviously. This is a word from the ancient language Latin, and was not invented by Peter André as some people here suggest.

Musical example disproving the Peter André theory would be the song "Twilight of the Gods" from 1987 by the German power metal band Helloween, where the word Insania is used in the lyrics.

A medical example would be Insania Paranoides, which means mainly to be paranoid of stalkers, or to have become insane from that paranoia.
