Andrew Denton had a long journey into the world that comprised of mentally ill people. He felt that one might feel good when at one point he had lost a mind and got it back again. The journey for Andrew started in 2007 Annual Mental Health Services Conference which was held in Melbourne. He met people from all walks of life who had been struggling with the mental illness. He said that the stories of the ghosts that are in the mind are surprising, frank and moving deeply.
