I would so read a book about this

Yeah.

There is a case of a woman, in college, she started hearing voices. They are constantly second guessing her. So she talks back to them, reassuring them that things are going to be OK. Its really interesting.

Sounds more like dissociative Identity disorder. Schizophrenia is seeing things that aren't there or voices, DID is when you have multiple personalities.

This made me think.....
