People Who Don't Believe

I don't believe in ghosts, gods, or Buddhas. But I can see them. Xu Nian is a psychological counselor and a firm atheist. The patients he faces every day all say the same thing: "I saw it." "I heard you." "It's been following me." Xu Nian will explain everything using psychology. He never admitted that he could see too. Until one day, a patient asked him: "Dr. Xu, why do you keep looking behind me?" Behind Xu Nian, stood a non-existent person. Do you choose to see it, or pretend not to see it?
