Aniela Jaffe "From the Life and Work of C.G. Jung"
Four essays on Jung by the woman who acted as his secretary in his last years. The interesting ones for me were (i) her memories of him in his old age and (ii) Her discussion of the accusations against him of involvement with the Nazis in the early 1930s.
There is also a good ghost story:
In his contribution to Fanny Moser's book, "Spuk: Wahrglaube oder Irrglaube?" (1950), Jung describes his own encounter with a ghost in England in 1920. He spent several weekends in a friend's recently rented country house. During the nights he experienced various increasingly violent ghostly phenomena like knockings, evil smells, sounds of rustling and dripping. They aroused in him a feeling of suffocation and a sensation of growing rigidity, and culminated in the apparition, or hallucination, of a solid-looking half of a woman's head lying on the pillow about sixteen inches away from his own. Its one eye was open and staring at him. The head vanished when Jung lit a candle. He spent the rest of the night sitting in an armchair. He and his friend later learned what was already known to the whole village: the house was haunted and all tenants were driven away in a very short time.
Jung interpreted some details of his experience as exteriorizations of psychic contents in the unconscious. But what remained an insoluble puzzle was the fact that the haunting took place solely in that house, indeed in one particular room of the house. During the week when he stayed in London, he slept peacefully in spite of a heavy working schedule. It was a typical case of localized haunting, for which to this day no adequate scientific explanation has been found. The house was pulled down shortly after Jung's visit.
