At one point, Dick felt that he had been taken over by the spirit of the prophet Elijah. He believed that an episode in his novel "Flow My Tears, the Policeman Said" was a detailed retelling of a biblical story from the Book of Acts, which he had never read. Dick documented and discussed his experiences and faith in a private journal he called his "exegesis", portions of which were later published as "The Exegesis of Philip K. Dick". The last novel Dick wrote was "The Transmigration of Timothy Archer"; it was published shortly after his death in 1982.
