Another kind of auto-erethism occurs during sleep. Pollutions are accompanied in sleep by erotic dreams. At the height of the paroxysm an abundant discharge from the Bartholinian glands takes place. The orgasm in sleep is an autoerotic process which is entirely normal. In women who have not yet experienced orgasm in the waking state, the erotic phenomena during sleep are usually of a very vague kind. The real orgasm that awakes the sleeper and leaves its traces in the individual’s consciousness occurs only after orgasm has been once induced in the waking state. Erotic dreams occur in women more frequently than is ordinarily thought of nowadays. It was better known in the darker ages. Hence the wide-spread belief in Lillith and Samaël, the evil spirits, that visit young maidens and wives and also youths and husbands while in bed at night in order to seduce them. Sometimes automatic masturbation is practised during sleep. The patient awakes to find her finger in the vagina. If the pollutions occur at long intervals, they cause no direct injury to a good constitution. But if the women are not robust, and the pollutions happen too often, these drains are the cause of considerable nervous depression. One of the author’s patients, a widow of about forty years of age, is suffering from almost nightly pollutions. These weaken her so much that she is seldom able to rise before noon-time. The same deleterious effects are caused by all other kinds of masturbatic practices. Even though we agree with Paget that moderate masturbation is no more harmful than normal intercourse, it can not be denied that masturbation, since opportunity for it is ever present, is of far more frequent occurrence than natural sexual indulgence. The habit, once established, masturbation presents an unconquerable impulse and a resultant incapacity to control it. It is then the cause of grave material injuries to the nervous system. It dwarfs the entire female organism. It makes the girl shy, offish, squeamish, repellent, and weakens and sickens the emotions of sex-attraction. One of the author’s patients, a dress-maker, thirty-five years of age and single, has been suffering from general nervousness, headaches, palpitation of the heart, frequent urination, anorexia and constipation. One day she took courage and asked for a remedy for her excessive autoeroticism. Scarcely does she reach her bed at night time and gets warm, when the overwhelming desire for autoeroticism takes a hold of her and, fighting as she may against the impulse, ei feminandum est manu. These practices were going on nightly for the last twenty years.
