Fodor compiles a number of dreams in which apparently telepathic elements may be considered as source of the dream elements. 'The telepathic message plays the same rôle as any other residue of the waking life, to be altered by the dream work, and to suit its own purpose.' He adds: 'In some rare cases, the telepathic influence becomes so overwhelming that the freedom of personal dream work is curtailed.' The author uses coincidences of details in his own dreams with details in the dreams of his wife or his daughter, or in dreams of his patients. Some of the examples are, it is true, very astonishing; others are less impressive because of the possibility of day residues or of commoon knowledge. Not one of the examples may be looked upon as full proof. The last example remains especially problematic: a friend of Fodor's tried the 'experiment' of making himself noticeable to him in dreams by telepathy, without Fodor's knowledge. Instead of Fodor, a patient of his produced a dream which seemed to correspond to the 'message'.
