      As stated, the patient's automatic writing never came to any very great development. In these experiments, generally carried out in darkness, she passed over into semi-somnambulism, or into ecstasy. The automatic writing had thus the same effect as the preliminary table-turning.

      3. The Hallucinations.—The nature of the passing into somnambulism in the second séance is of psychological importance. As stated, the automatic phenomena were progressing favourably when darkness came on. The most interesting event of this séance, so far, was the brusque interruption of the communication from the grandfather, which was the starting-point of various debates amongst the members of the circle. These two momentous occurrences, the darkness and the striking event, seem to have been the foundation for a rapid deepening of hypnosis, in consequence of which the hallucinations could be developed. The psychological mechanism of this process seems to be as follows. The influence of darkness upon the suggestibility of the sense-organs is well known.[39] Binet[40] states that it has a special influence on hysterics, producing a state of sleepiness. As is clear from the foregoing, the patient was in a state of partial hypnosis and had constituted herself one with the unconscious personality in closest relationship to her in the domain of speech. The automatic expression of this personality is interrupted most unexpectedly by a new person, of whose existence no one had any suspicion. Whence came this cleavage? Obviously the eager expectation of this first séance had very much occupied the patient. Her reminiscences of me and my family had probably grouped themselves around this expectation; hence these suddenly come to light at the climax of the automatic expression. That it was just my grandfather and no one else—not, e.g., my deceased father, who, as she knew, was much closer to me than the grandfather whom I had never known—perhaps suggests where the origin of this new person is to be sought. It is probably a dissociation of the personality already present which seized upon the material next at hand for its expression, namely, upon the associations concerning myself. How far this is parallel to the experiences revealed by dream investigation (Freud's[41]) must remain undecided, for we have no means of judging how far the effect mentioned can be considered a "repressed" one. From the brusque interruption of the new personality, we may conclude that the presentations concerned were very vivid, with corresponding intensity of expectation. This perhaps was an attempt to overcome a certain maidenly shyness and embarrassment. This event reminds us vividly of the manner in which the dream presents to consciousness, by a more or less transparent symbolism, things one has never said to oneself clearly and openly. We do not know when this dissociation of the new personality occurred, whether it had been slowly prepared in the unconscious, or whether it first occurred in the séance. In any case, this event meant a considerable increase in the extension of the unconscious sphere rendered accessible through the hypnosis. At the same time this event must be regarded as powerfully suggestive in regard to the impression which it made upon the waking consciousness of the patient. For the perception of this unexpected intervention of a new power must inevitably excite a feeling of the strangeness of the automatisms, and would easily suggest the thought that an independent spirit is here making itself known. Hence the intelligible association that she would finally be able to see this spirit. The situation that ensued at the second séance is to be explained by the coincidence of this energising suggestion with the heightened suggestibility conditioned by the darkness. The hypnosis, and with it the series of dissociated presentations, break through to the visual area, and the expression of the unconscious, hitherto purely motor, is made objective, according to the measure of the specific energy of the new system, in the shape of visual images with the character of hallucinations; not as a mere accompanying phenomenon of the word-automatism, but as a substituted function. The explanation of the situation that arose in the first séance, at that time unexpected and inexplicable, is no longer presented in words, but as a descriptive allegorical vision. The sentence "they do not hate one another, but are friends," is expressed in a picture. We often encounter events of this kind in somnambulism. The thinking of somnambulists is given in plastic images which constantly break into this or that sense-sphere and are made objective in hallucinations. The process of reflection sinks into the subconscious; only its end-results arise to consciousness either as presentations vividly tinged by the senses, or directly as hallucinations. In our case the same thing occurred as in the patient whose anæsthetic hand Binet pricked nine times, making her think of the figure 9; or as in Flournoy's[42] Helen Smith, who, when asked during business-hours about certain patterns, suddenly saw the number of days (18) for which they had been lent, at a length of 20 mm. in front of her. The further question arises, why does the automatism appear in the visual and not in the acoustic sphere? There are several grounds for this choice of the visual sphere.

      (1) The patient is not gifted acoustically; she is, for instance, very unmusical.

      (2) There was no stillness corresponding to the darkness which might have favoured the appearance of sounds; there was a lively conversation.

      (3) The increased conviction of the near presence of spirits, because the automatism felt so strange, could easily have aroused the idea that a spirit might be seen, thus causing a slight excitation of the visual sphere.

      (4) The entoptic phenomena in darkness favoured the occurrence of hallucinations.

      The reasons (3) and (4)—the entoptic phenomena in the darkness and the probable excitation of the visual sphere—are of decisive importance for the appearance of hallucinations. The entoptic phenomena in this case play the same rôle in the auto-suggestion, the production of the automatism, as the slight tactile stimuli in hypnosis of the motor centre. As stated, flashes preceded the first hallucinatory twilight-state. Obviously attention was already at a high pitch, and directed to visual perceptions, so that the retina's own light, usually very weak, was seen with great intensity. The part played by entoptic perceptions of light in the origin of hallucinations deserves further consideration. Schüle[43] says: "The swarming of light and colour which stimulates and animates the field of vision, although in the dark, supplies the material for phantastic figures in the air before falling asleep. As we know, absolute darkness is never seen; a few particles of the dark field of vision are always illumined; flecks of light move here and there, and combine into all kinds of figures; it only needs a moderately active imagination to create out of them, as one does out of clouds, certain known figures. The power of reasoning, fading as one falls asleep, leaves phantasy free play to construct very vivid figures. In the place of the light spots, haziness and changing colours of the dark visual field, there arise definite outlines of objects."[44]

      In this way hypnagogic hallucinations arise. The chief rôle naturally belongs to the imagination, hence imaginative people in particular are subject to hypnagogic hallucinations.[45] The hypnopompic hallucinations described by Myers arise in the same way.

      It is highly probable that hypnagogic pictures are identical with the dream-pictures of normal sleep—forming their visual foundation. Maury[46] has proved from self-observation
