The case of H. O. is the same in principle as I interpret it, but is distinguished by the fact that the dissociation of processes was not so extreme. The obsessing idea was in the ultramarginal zone of consciousness and, to this extent, subconscious. Briefly stated, H. O. for many years was the victim of an intense obsession, in consequence of which she had practically foregone social life, and found herself unable to travel for fear she would be afflicted with her psychosis in trains, etc. The physical symptom was intense nausea suddenly arising as an attack. When attacked with this there developed also depression and a mental state which is perhaps best described as a mood. She could give no explanation of the attacks. On examination it developed that always in the “background of her mind,” just preceding the attack, there came the idea of disgust of self. At once the nausea as the physical expression of disgust was experienced. The disgust-idea was always excited by some associated stimulus. The meaning of this “sentiment” was set in a large complex of past experiences. Into all this I will not go. The point is that the only conscious elements of her obsession were in the extreme fringe of consciousness, sufficiently dissociated to be practically coconscious,[175] but the _physical symptoms_ were distressingly prominent. _Relief was easily effected simply by organizing a new complex giving a new point of view of self._ Complexes consisting entirely of the physiological manifestations of emotion without conscious emotion undoubtedly occur. A long time ago I described such a neurosis under the name of Fear Neurosis[176] in distinction from psychosis. The symptom complex was interpreted as a persisting automatism derived from antecedent fear states that had been outgrown. From our present standpoint and fuller knowledge we must believe that underlying this automatism is probably an unconscious complex of these antecedent experiences including the fear which takes part in the functioning mechanism. It may be called, then, a subconscious psychosis. True _hysterical laughter and crying_ are undoubtedly phenomena of this type and due to the same mechanism. These phenomena are well known to be purely automatic; that is to say, they are emotional manifestations unaccompanied in consciousness by thoughts or even by emotions corresponding to them. The subject laughs or cries without knowing why and without even feeling merry or sad. I forbear to digress sufficiently to present the evidence for the interpretation that the phenomena are due to subconscious processes of the kind just described. Let me merely say that in one instance, N. O., intensely studied, the automatic crying was traced by experimental and clinical methods to a persisting and often insistent subconscious childhood’s perception and meaning of self—as a lonely, unhappy child. This perception, etc., could be differentiated from the conscious perception belonging to adult age.
