growth of repressed thoughts. We can now comprehend why the hallucinatory persons are separated from those who write and speak automatically. The former teach Ivenes the secrets of the Other Side, they relate all those phantastic tales about the extraordinariness of her personality, they create scenes where Ivenes can appear dramatically with the attributes of power, wisdom and virtue. These are nothing but dramatic dissociations of her dream-self. The latter, the automatic persons, are the ones to be overcome, they must have no part in Ivenes. With the spirit-companions of Ivenes they have only the name in common. A priori, it is not to be expected that in a case like ours, where these divisions are never clearly defined, that two such characteristic individualities should disappear entirely from a somnambulic ego-complex having so close a relation with the waking consciousness. And in fact, we do meet them in part in those ecstatic penitential scenes and in part in the romances crammed with more or less banal, mischievous gossip.
Course.
It only remains to say a few words about the course of this strange affection. The process reached its maximum in four to eight weeks. The descriptions given of Ivenes and of the unconscious personalities belong generally to this period. Thenceforth a gradual decline was noticeable; the ecstasies grew meaningless and the influence of Gerbenstein became more powerful. The phenomena gradually lost their distinctive features, the characters which were at first well demarcated became by degrees inextricably mixed. The psychological contribution grew smaller and smaller until finally the whole story assumed a marked effect of fabrication. Ivenes herself was much concerned about this decline; she became painfully uncertain, spoke cautiously, feeling her way, and allowed her character to appear undisguised. The somnambulic attacks decreased in frequency and intensity. All degrees from somnambulism to conscious lying were observable. Thus the curtain fell. The patient has since gone abroad. We should not underestimate the importance of the fact that her character has become pleasanter and more stable. Here we may recall the cases cited in which the second state gradually replaced the first state. Perhaps this is a similar phenomenon.
It is well known that somnambulic manifestations sometimes begin at puberty.[107] The attacks of somnambulism in Dyce's case[108] began immediately before puberty and lasted just till its termination. The somnambulism of H. Smith is likewise closely connected with puberty.[109]
Schroeder von der Kalk's patient was 16 years old at the time of her illness; Felida 14–½, etc. We know also that at this period the future character is formed and fixed. In the case of Felida and of Mary Reynolds we saw that the character in state II. replaced that of state I. It is not therefore unthinkable that these phenomena of double consciousness are nothing but character-formations for the future personality, or their attempts to burst forth. In consequence of special difficulties (unfavourable external conditions, psychopathic disposition of the nervous system, etc.), these new formations, or attempts thereat, become bound up with peculiar disturbances of consciousness. Occasionally the somnambulism, in view of the difficulties that oppose the future character, takes on a marked teleological meaning, for it gives the individual, who might otherwise be defeated, the means of victory. Here I am thinking first of all of Jeanne d'Arc, whose extraordinary courage recalls the deeds of Mary Reynolds' II. This is perhaps the place to point out the similar function of the "hallucination téléologique" of which the public reads occasionally, although it has not yet been submitted to a scientific study.
The Unconscious Additional Creative Work.
We have now discussed all the essential manifestations offered by our case which are of significance for its inner structure. Certain accompanying manifestations may be briefly considered: the unconscious additional creative work. Here we shall encounter a not altogether unjustifiable scepticism on the part of the representative of science. Dessoir's conception of a second ego met with much opposition, and was rejected, as too impossible in many directions. As is known, occultism has proclaimed a pre-eminent right to this field and has drawn premature conclusions from doubtful observations. We are indeed very far from being in a position to state anything conclusive, since we have at present only most inadequate material. Therefore if we touch on the field of the unconscious additional creative work, it is only that we may do justice to all sides of our case. By unconscious addition we understand that automatic process whose result does not penetrate to the conscious psychic activity of the individual. To this region above all belongs thought-reading through table movements. I do not know whether there are people who can divine a whole long train of thought by means of inductions from the intentional tremulous movements. It is, however, certain that, assuming this to be possible, such persons must be availing themselves of a routine achieved after endless practice. But in our case long practice can be excluded without more ado, and there is nothing left but to accept a primary susceptibility of the unconscious, far exceeding that of the conscious.
This supposition is supported by numerous observations on somnambulists. I will mention only Binet's[110] experiments, where little letters or some such thing, or little complicated figures in relief were laid on the anæsthetic skin of the back of the hand or the neck, and the unconscious perceptions were then recorded by means of signs. On the basis of these experiments he came to the following conclusion: "D'après les calculs que j'ai pu faire, la sensibilité inconsciente d'une hystérique est à certains moments cinquante fois plus fine que celle d'une personne normale." A second additional creation coming under consideration in our case and in numerous other somnambulists, is that condition which French investigators call "cryptomnesia."[111] By this term is meant the becoming conscious of a memory-picture which cannot be regarded as in itself primary, but at most is secondary, by means of subsequent recalling or abstract reasoning. It is characteristic of cryptomnesia that the picture which emerges does not bear the obvious mark of the memory-picture, is not, that is to say, bound up with the idiosyncratic super-conscious ego-complex.
Three ways may be distinguished in which the cryptomnesic picture is brought to consciousness.
1. The picture enters consciousness without any intervention of the sense-spheres (intra-psychically). It is an inrushing idea whose causal sequence is hidden within the individual. In so far cryptomnesia is quite an everyday occurrence, concerned with the deepest normal psychic events. How often it misleads the investigator, the author or the composer into believing his ideas original, whilst the critic quite well recognises their source! Generally the individuality of the representation protects the author from the accusation of plagiarism and proves his good faith; still, cases do occur of unconscious verbal reproduction. Should the passage in question contain some remarkable idea, the accusation of plagiarism, more or less conscious, is justified. After all, a valuable idea is linked by numerous associations with the ego-complex; at different times, in different situations, it has already been meditated upon and thus leads by innumerable links in all directions. It can therefore never so disappear from consciousness that its continuity could be entirely lost from the sphere of conscious memory. We have, however, a criterion by which we can always recognise objectively intra-psychic cryptomnesia. The cryptomnesic presentation is linked to the ego-complex by the minimum of associations. The reason for this lies in the relation of the individual to the particular object, in the disproportion of interest to object. Two possibilities occur: (1) The object is worthy of interest but the interest is slight in consequence of dispersion or want of understanding; (2) The object is not worthy of interest, consequently the interest is slight. In both cases an extremely labile connection with consciousness arises which leads to a rapid forgetting. The slight bridge is soon destroyed and the acquired presentation sinks into the unconscious, where it is no longer accessible to consciousness. Should it enter consciousness by means of cryptomnesia, the feeling of strangeness, of its being an original creation, will cling to it because the path by which it entered the subconscious has become undiscoverable. Strangeness and original creation are, moreover, closely allied to one another if one recalls the numerous witnesses in belles-lettres to the nature of genius ("possession" by genius).[112]
Apart from certain striking cases of this kind, where it is doubtful whether it is a cryptomnesia or an original creation, there are some cases in which a passage of no essential content is reproduced, and that almost verbally, as in
