The influence of darkness upon the suggestibility of the sense-organs is well known.[1] Binet[2] 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[3]) 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
