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.
