Clinical psychologist Professor Daniel Freeman continues his exploration of delusions, looking at both historic and contemporary case studies.

In this programme he hears a case from 1892, of a patient at the Victorian psychiatric hospital Bethlem in London who believed that people were telephoning into her ears. And he meets a man who experienced delusions of being dead and under attack as a consequence of being in a hospital intensive care unit.
