The persons in the dream were not recognized simply because there was no need for them to be; the dream expressed the pertinent meaning just as well without them as with them. They were observed just as many of us would observe the occupants of a street car in waking life; we could possibly not describe, even partly, any one of the occupants of the car which we used on our way to the office or home. Before leaving this nightmare, I want to call attention again to the somatic elements. I was lying on my back and in a cramped position, the air was closer than usual, and my circulation was naturally deranged. When I awoke I was strongly inclined to give the physical elements a large amount of the responsibility for the dream, and I have not found occasion to change my mind in this matter. I think that even the inability to jump through the window in the dream was caused by the weak and exhausted state of my body, due to the poor circulation and cramped position. ANALYSIS OF A SINGLE DREAM AS A MEANS OF UNEARTHING THE GENESIS OF PSYCHOPATHIC AFFECTIONS BY MEYER SOLOMON, MD., CHICAGO THOSE; of us who have devoted a certain amount of our time and energy to the study of dreams have early come to realize the value of a dream as a starting-point in the analysis of certain mental states, particularly those of an abnormal character. Frequently, in the hopeless tangle of symptoms, complaints and disconnected facts in the history as originally obtained, especially in old-standing cases, one does not really know just where to begin, what to start with in the first efforts to struggle with the problem of the ultimate genesis and evolution of the condition which is presented to him at the particular moment. Of course, by a careful review of the patient's past life history, gone over by persistent questioning and cross-examination, one can begin with the family history and step by step trace the history of the patient from earliest childhood or infancy through the various stages and phases of activity and development up to the very moment of examination. This may at times appear quite dull, quite uninteresting and entirely unnecessary to certain patients. For this reason and also for many other reasons, which I shall not enumerate at this point it is at times well to resort to dream analysis. And in analyzing dreams it is well to remember a fact, with which I believe all psychoanalysts will agree, namely, that by a most thorough and far-reaching analysis of a SINGLE DREAM, we can, by following out to the ultimate ends the various clues which are given us and the various by-paths which offer themselves to us in the course of the analysis--we can, I repeat, should we be so inclined, root up the entire life history of the dreamer. This may not be necessary in all cases. But, at any rate, if we desired so to do for scientific purposes, we could arrive at such results. In such an analysis we would, of course, first take up, individually, every
