The earlier the age at which the child begins to ripen sexually, the earlier do sexual dreams and nocturnal ejaculations make their appearance. I have known of numerous instances in which children ten or eleven years of age have had sexual dreams; occasionally, even, I have been informed of the occurrence of such dreams in children of seven or eight years of age. In children, as in adults, the object which is sexually exciting in the waking state plays a leading part in the sexual dream. But in the sexual dreams of children the imagination is even more active than it is in the sexual dreams of adults. All kinds of perverse dreams may, in children, accompany the emission, even when the corresponding ideas have no erotic association in the waking state. Things of which the child has learned from fairy tales, stories of robbers, of imprisoned or enchanted princesses, princes, fettered slaves--all may play a part in the psychosexual processes of the dream-life. Anyone unaware of the fact that in the great majority of children this tendency disappears spontaneously in the course of the further development of the sexual life might too readily infer the existence of some morbid perversion. In such instances we must, indeed, bear in mind the possibility of sexual perversion, especially in view of the fact that sexually perverse adults are often able to trace back into childhood the memory of sexual dreams characteristic of their peculiar type of perversion. Occasionally the feelings of anxiety of which we have spoken above may, even in dreams, lead to the occurrence of involuntary ejaculations. Thus we are told of dreams of pursuit by robbers or by wild animals, or of dreams of missing a train the dreamer has been running to catch, in which ejaculations occur. In isolated cases the dreams of children which are associated with ejaculations may be quite indistinct; in such cases, just as sometimes in the sexual dreams of adults, it is impossible to recognise any definite relationship to the psychosexual feelings of the waking state. In this connexion no difference between the sexes can be shown to exist, except this, that, at any rate as far as my own experience goes, nocturnal ejaculations are much more often absent in girls than in boys. Occasionally, manual or other artificial stimulation of the genital organs is effected during sleep; I have myself known several instances of this, both in boys and in girls. In several cases, at least, there were satisfactory grounds for believing that we were not concerned with masturbation practised at night in the waking state, but all the indications pointed to the fact that the processes wore carried on unconsciously during sleep. In isolated cases I have had children watched throughout the night, in order to clear up this point, and my conclusion was thus confirmed that children do at times play with the genital organs during sleep.
