“About six months later my beloved mother, who was not living with us, became ill. My wife left home to nurse her mother-in-law. The patient’s condition became serious and gave my wife the opportunity to show the best side of herself. One evening I returned home full of enthusiasm over what my wife had accomplished, and felt very grateful to her. I stepped to my desk and, without definite intention but with the certainty of a somnambulist, I opened a certain drawer, and in the very top of it I found the long-missing, mislaid book.” The following example of “misplacing” belongs to a type well known to every psychoanalyst. I must add that the patient who experienced this misplacing has himself found the solution of it. This patient, whose psychoanalytic treatment had to be interrupted through the summer vacation when he was in a state of resistance and ill-health, put away his keys in the evening in their usual place, or so he thought. He then remembered that he wished to take some things from his desk, where he also had put the money which he needed on the journey. He was to depart the next day, which was the last day of treatment and the date when the doctor’s fee was due. But the keys had disappeared. He began a thorough and systematic search through his small apartment. He became more and more excited over it, but his search was unsuccessful. As he recognized this “misplacement” as a symptomatic act--that is, as being intentional--he aroused his servant in order to continue his search with the help of an “unprejudiced” person. After another hour he gave up the search and feared that he had lost the keys. The next morning he ordered new keys from the desk factory, which were hurriedly made for him. Two acquaintances who had been with him in a cab even recalled hearing something fall to the ground as he stepped out of the cab, and he was therefore convinced that the keys had slipped from his pocket. They were found lying between a thick book and a thin pamphlet, the latter a work of one of my pupils, which he wished to take along as reading matter for his vacation; and they were so skilfully placed that no one would have supposed that they were there. He himself was unable to replace the keys in such a position as to render them invisible. The unconscious skill with which an object is misplaced on account of secret but strong motives reminds one of “somnambulistic sureness.” The motive was naturally ill-humour over the interruption of the treatment and the secret rage over the fact that he had to pay such a high fee when he felt so ill.
