In the Vertigo Comics one-shot "Vertigo Visions: Doctor 13 – Do AIs Dream of Electric Sheep?", Dr. Terrence Thirteen and his wife Marie go to marriage counseling, as Marie is becoming increasingly alienated from Terrence due to his overbearing behavior and the fact that he refuses to take payment for his services and therefore lives off her bank account. Dr. Thirteen becomes trapped in a virtual reality and embroiled in a conflict between benign and malicious artificial intelligences with the ability to manipulate media and sensory perceptions on a global scale. At the conclusion of the comic, Dr. Thirteen is seen in a mental institution, having apparently suffered a mental breakdown during the visit to the marriage counselor and hallucinated everything, although the AIs are also seen to be real.
