He paused, then added quickly: “What machine was it in this case? I have samples here from that of Dr. Boss, from a machine used by Mr. Masterson’s secretary, and from a machine which was accessible to both Mr. and Mrs. Maitland.”
Kennedy stopped, but he was not yet prepared to relieve the suspense of two of those whom his investigation would absolve.
“Just one other point,” he resumed mercilessly, “a point which a few years ago would have been inexplicable—if not positively misleading and productive of actual mistake. I refer to the dreams of Mrs. Maitland.”
I had been expecting it, yet the words startled me. What must they have done to her? But she kept admirable control of herself.
“Dreams used to be treated very seriously by the ancients, but until recently modern scientists, rejecting the ideas of the dark ages, have scouted dreams. To-day, however, we study them scientifically, for we believe that whatever is, has a reason. Dr. Ross, I think, is acquainted with the new and remarkable theories of Dr. Sigmund Freud, of Vienna?”
Dr. Ross nodded. “I dissent vigorously from some of Freud’s conclusions,” he hastened.
“Let me state them first,” resumed Craig. “Dreams, says Freud, are very important. They give us the most reliable information concerning the individual. But that is only possible”—Kennedy emphasised the point—“if the patient is in entire rapport with the doctor.
“Now, the dream is not an absurd and senseless jumble, but a perfect mechanism and has a definite meaning in penetrating the mind. It is as though we had two streams of thought, one of which we allow to flow freely, the other of which we are constantly repressing, pushing back into the subconscious, or unconscious. This matter of the evolution of our individual mental life is too long a story to bore you with at such a critical moment.
“But the resistances, the psychic censors of our ideas, are always active, except in sleep. Then the repressed material comes to the surface. But the resistances never entirely lose their power, and the dream shows the material distorted. Seldom does one recognise his own repressed thoughts or unattained wishes. The dream really is the guardian of sleep to satisfy the activity of the unconscious and repressed mental processes that would otherwise disturb sleep by keeping the censor busy. In the case of a nightmare the watchman or censor is aroused, finds himself overpowered, so to speak, and calls on consciousness for help.
“There are three kinds of dreams—those which represent an unrepressed wish as fulfilled, those that represent the realisation of a repressed wish in an entirely concealed form, and those that represent the realisation of a repressed wish in a form insufficiently or only partially concealed.
