Psychiatrymiddle twist
A 22-year-old Aboriginal man is brought to a regional hospital by his aunt six weeks after his grandfather's funeral. At night he hears his grandfather calling his name, and he has twice seen him standing at the edge of the yard; he finds this comforting rather than frightening. He has been tearful and has stopped playing football, but his mood lifts when friends visit and he is sleeping, eating and working normally. His aunt says this happens in their family after a death and that it happened to her. There is no other perceptual disturbance and no disorder of thought form. Which one of the following best accounts for his experiences?
