body when awake, is not likely to see it when asleep, even in dreams of women; in the second place, the confusions and combinations of dream imagery often tend to obliterate sexual distinctions, however free from perversions the subjects may be. Thus, a correspondent tells me of a healthy man, of very pure character, totally inexperienced in sexual matters, and never having seen a woman naked, who, in his sexual dreams, always sees the woman with male organs, though he has never had any sexual inclinations for men, and is much in love with a lady. The confusions and associations of dream imagery, leading to abnormal combinations, may be illustrated by a dream which once occurred to me after reading Joest's account of how a young negress, whose tattoo-marks he was sketching, having become bored, suddenly pressed her hands to her breasts, spirting two streams of lukewarm milk into his face, and ran away laughing; I dreamed of a woman performing a similar action, not from her breasts, however, but from a penis with which she was furnished. Again, by another kind of confusion, a man dreams sexually that he is with a man, although the figure of the partner revealed in the dream is a woman. The following dream, in a normal man who had never been, or wished to be, in the position shown by the dream, may be quoted: "I dreamed that I was a big boy, and that a younger boy lay close beside me, and that we (or, certainly, he) had seminal emissions; I was complacently passive, and had a feeling of shame when the boy was discovered. On awaking I found I had had no emission, but was lying very close to my wife. The day before, I had seen boys in a swimming-match." This was, it seems to me, an example of dream confusion, and not an erotic inverted dream. (Näcke also brings forward inverted dreams by normal persons; see e.g. his "Beiträge zu den sexuellen Träumen," Archiv für Kriminal-Anthropologie, Bd. XX, 1908, p. 366.)
So far as I have been able to ascertain, there seem to be, generally speaking, certain differences in the manifestations of auto-erotism during sleep in men and women which I believe to be not without psychological significance. In men the phenomenon is fairly simple; it usually appears about puberty continues at intervals of varying duration during sexual life provided the individual is living chastely, and is generally, though not always, accompanied by erotic dreams which lead up to the climax, its occurrence being, to some extent, influenced by a variety of circumstances: physical, mental, or emotional excitement, alcohol taken before retiring, position in bed (as lying on the back), the state of the bladder, sometimes the mere fact of being in a strange bed, and to some extent apparently by the existence of monthly and yearly rhythms. On the whole, it is a fairly definite and regular phenomenon which usually leaves little conscious trace on awaking, beyond probably some sense of fatigue and, occasionally, a headache. In women, however, the phenomena of auto-erotism during sleep seem to be much more irregular, varied, and diffused. So far as I have been able to make inquiries, it is the exception rather than the rule for girls to experience definitely erotic dreams about the period of puberty or adolescence.[238] Auto-erotic phenomena during sleep in women who have never experienced the orgasm when awake are usually of a very vague kind; while it is the rule in a chaste youth for the orgasm thus to manifest itself, it is the exception in a chaste girl. It is not, as a rule, until the orgasm has been definitely produced in the waking state—under whatever conditions it may have been produced—that it begins to occur during sleep, and even in a strongly sexual woman living a repressed life it is often comparatively infrequent.[239] Thus, a young medical woman who endeavors to deal strenuously with her physical sexual emotions writes: "I sleep soundly, and do not dream at all. Occasionally, but very rarely, I have had sensations which awakened me suddenly. They can scarcely be called dreams, for they are mere impulses, nothing connected or coherent, yet prompted, I know, by sexual feeling. This is probably an experience common to all." Another lady (with a restrained psycho-sexual tendency to be attracted to both sexes), states that her first sexual sensations with orgasm were felt in dreams at the age of 16, but these dreams, which she has now forgotten, were not agreeable and not erotic; two or three years later spontaneous orgasm began to occur occasionally when awake, and after this, orgasm took place regularly once or twice a week in sleep, but still without erotic dreams; she merely dreamt that the orgasm was occurring and awoke as it took place.
It is possible that to the comparative rarity in chaste women of complete orgasm during sleep, we may in part attribute the violence with which repressed sexual emotion in women often manifests itself.[240] There is thus a difference here between men and women which is of some significance when we are considering the natural satisfaction of the sexual impulse in chaste women.
In women, who have become accustomed to sexual intercourse, erotic dreams of fully developed character occur, with complete orgasm and accompanying relief—as may occasionally be the case in women who are not acquainted with actual intercourse;[241] some women, however, even when familiar with actual coitus, find that sexual dreams, though accompanied by emissions, are only the symptoms of desire and do not produce actual relief.
Some interest attaches to cases in which young women, even girls at puberty, experience dreams of erotic character, or at all events dream concerning coitus or men in erection, although they profess, and almost certainly with truth, to be quite ignorant of sexual phenomena. Several such dreams of remarkable character have been communicated to me. One can imagine that the psychologists of some schools would see in these dreams the spontaneous eruption of the experiences of the race. I am inclined to regard them as forgotten memories, such as we know to occur sometimes in sleep. The child has somehow seen or heard of sexual phenomena and felt no interest, and the memory may subsequently be aroused in sleep, under the stimulation of new-born sexual sensations.
It is a curious proof of the ignorance which has prevailed in recent times concerning the psychic sexual nature of women that, although in earlier ages the fact that women are normally liable to erotic dreams was fully recognized, in recent times it has been denied, even by writers who have made a special study of the sexual impulse in women. Eulenburg (Sexuale Neuropathie, 1895, pp. 31, 79) appears to regard the appearances of sexual phenomena during sleep, in women, as the result of masturbation. Adler, in what is in many respects an extremely careful study of sexual phenomena in women (Die Mangelhafte Geschlechtsempfindung des Weibes, 1904, p. 130), boldly states that they do not have erotic dreams. In 1847, E. Guibout ("Des Pollutions Involontaires chez la Femme," Union Médicale, p. 260) presented the case of a married lady who masturbated from the age of ten, and continued the practice, even after her marriage at twenty-four, and at twenty-nine began to have erotic dreams with emissions every few nights, and later sometimes even several times a night, though they ceased to be voluptuous; he believed the case to be the first ever reported of such a condition in a woman. Yet, thousands of years ago, the Indian of Vedic days recognized erotic dreams in women as an ordinary and normal occurrence. (Löwenfeld quotes a passage to this effect from the Oupnek'hat, Sexualleben und Nervenleiden, 2d ed., p. 114.) Even savages recognize the occurrence of erotic dreams in women as normal, for the Papuans, for instance, believe that a young girl's first menstruation is due to intercourse with the moon in the shape of a man, the girl dreaming that a man is embracing her. (Reports Cambridge Expedition to Torres Straits, vol. v., p. 206.) In the seventeenth century, Rolfincius, in a well-informed study (De Pollutione Nocturna, a Jena Inaugural Dissertation, 1667), concluded that women experience such manifestations, and quotes Aristotle, Galen, and Fernelius, in the same sense. Sir Thomas Overbury, in his Characters, written in the early part of the same century, describing the ideal milkmaid, says that "her dreams are so chaste that she dare tell them," clearly implying that It was not so with most women. The notion that women are not subject to erotic dreams thus appears to be of comparatively recent origin.
One of the most interesting and important characters by which the erotic dreams of women—and, indeed, their dreams generally—differ from those of men is in the tendency to evoke a repercussion on the waking life, a tendency more rarely noted in men's erotic dreams, and then only to a minor extent. This is very common, even in healthy and normal women, and is exaggerated to a high degree in neurotic subjects, by whom the dream may even be interpreted as a reality, and so declared on oath, a fact of practical
