by Freud and Breuer, written in 1893 and entitled 'Über den psychischen Mechanismus der hysterischen Phenomene.' If you care to take the trouble to read it, you will see that it is an exposition of the application of the term 'Somnambulismus' to certain temporary neurotic derangements.—And here also is Freud's 'Traumdeutung,' published in 1894, in which this terminology is explained and amplified.—In addition to these, I have here 'Nervöse Angstzustände,' by Stekel, who, though he leads one of the most important schisms in the Freudian school, uses the same nomenclature in referring to split personality." He laid the three books on the table before Vance. "You may take them along if you like. They may throw some light on the quandary you are in."
"You are inclined to believe, then, that both Schwarzwald and Brügelmann refer to waking psychic states rather than the more common type of somnambulism?"
"Yes, I am inclined to that belief. I know Schwarzwald was a former lecturer at the Psychopatisches Institut, in constant contact with Freud and his teachings. But, as I told you, I am not familiar with either of the books."
"How would you account for the term 'hysteria' in both titles?"
"Its presence there is in no way contradictory. Aphasia, amnesia, aphonia—and often anosmia and apnœa—are symptoms of hysteria. And hysterical paralysis is quite common. There are many cases of paralytics who have been unable to move a muscle for years, as a result of sheer hysteria."
