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.
