Karoline Ollson was born in 1861 in a small town of Sweden. At the age of 14, at the onset of her menstruation, she once came home complaining of toothache, went to bed and remained bedridden till 1908. For thirty-two years she slept all day and all night, waking up now and then for a few minutes, taking dim notice of happenings in her environment and speaking a few words. Two glasses of milk a day seemed to be sufficient to sustain her. She was kept for a fortnight in a hospital from which she was discharged when her ailment was diagnosed as "hysteria." When her mother died in 1905 she woke up and wept as long as the corpse remained in the house. Then she became quiet again and resumed her slumbers. In April, 1908, when her menstruation stopped, she woke up, left her bed and has led a normal life since. Dr. Toedenström who describes the case states that she looked incredibly young. Two weeks after she left her bed she had become strong enough to take charge of the household. Stekel, discussing this strange case in one of his lectures, said: "This woman spent the entire time of her womanhood in sleep, for she fell asleep at the time of her first menstruation period and her awakening coincided with her climacteric. She was a child and wished to remain a child. The first question she asked on arising, 'Where is mama?' shows that she was suffering from psychic infantilism. It is probable that dreams of childhood filled her thirty-year sleep and she may even have dreamt that she was still an unborn child for whom life had not yet begun." Medical literature contains many reports of freakish cases in which the subject falls asleep suddenly, while attending to duties of an uninteresting character; a young waiter, for instance, falling asleep while waiting on a table, remaining absolutely motionless for a whole minute and then waking up and resuming his work. Manacéine mentions two similar cases she observed personally. Both patients were illiterate and of slow intellect. One of them, a housemaid of nineteen, was a sound sleeper at night and yet, in the day time, one could never be sure of her remaining awake. She fell asleep once in the act of announcing a visitor and while bringing in a tray loaded with cups of coffee. The other was a woman of fifty, who was employed as a nurse until one day, falling asleep suddenly, she dropped an infant on the floor and almost killed him. In both the pulse was remarkably slow (a vagotonic symptom): in the girl it varied from 50 to 70 when awake, in the older woman from 40 to 60.
