Thanks. I asked because I worked with someone who had a psychotic break once. This person is very good with a particular kind of lyricism, and an unbelievable freestyler. When they were sick, sometimes they'd be ranting or arguing about something and suddenly break into improvised complex rhyme schemes. They'd sorta stay on topic. It was certainly not in situations you'd consider appropriate, but neither did it descend into word salad or anything. It many ways it was very impressive.
