My wife was just talking about some guy she had read about that is a genius, but had to deal with hearing voices. He finally got to the point where he could determine which voices were real, and which were fake - based on moral values IIRC.
However, after leaving the classroom where he taught math at some University, some big wig was waiting for him to give him the news that he had won some big award (like a Nobel or something). The professor grabbed a student walking nearby and said “Do you see this guy standing in front of me!?”
I knew a gal that was paranoid schzofrenic that was always calling the police on the nearby University, Hospital, etc. that they were doing mind control on her. But after attacking the police when they would show up at her door to try to “help” a few times, they just quit coming.
