More difficult seems to me the answer to the second main question: What influence does the moon exercise upon the sleeper? It was earlier discussed, along with the various psychical overdeterminations, that the moonlight awoke first the infantile pleasure memories, among other things that that light shining everywhere lighted the way which led to the house and the dwelling of the earliest childhood. Mention was made of the infantile comparison of the moon's disk with the childish nates and perhaps the gazing upon the nightly orb, which seems besides most like a hypnotic fixation, may be also referred back to the same. Since we know today that the love transference constitutes the essential character of hypnotism, that symptom brings us once more to the eroticism. Beside there was not wanting with our patient a grossly sensual relationship. Finally there is also the infantile desire to climb over the houses into the moon, realizing itself in part at least in the moon-inspired climbing upon the roof. Yet the second leading problem appears to me, in spite of all this, not completely exhausted. It might not thus be absolutely ruled out that more than a mere superstition lurks behind the folk belief which conceives of a "magnetic" influence by which the moon attracts the sleeper. Such a relationship is indeed conceivable when we consider the motor overexcitability of all sleep walkers and the effecting of ebb and flow through the influence of the moon. Furthermore no one, in an epoch which brings fresh knowledge each year of known and unknown rays, can deny without question any influence to the rays of moonlight. Perhaps in time the physicist and the astronomer will clear up the matter for us. Meanwhile the question is raised and can be answered only with an hypothesis. In conclusion I have in mind a last final connection which the spell of the moon bears to belief in spirits and ghosts. It is established through many analyses that the visits of the mother by night form the basis of the latter, when she comes with the light in her hand and scantily clothed in white garments, nightgown, or chemise and petticoat, to see if the children are asleep or, if they are, to set a child upon the chamber. The so often mentioned "woman in white" may also be the maiden in her nightgown, who thus exhibits herself in her night garment to her parents as she climbs into their bed, later also eventually to her lover. The choice of the hour between twelve and one, which came to be called the ghostly hour, may perhaps be referred to the fact that at this time sleep was most profound and therefore there was least danger of discovery.
