they have stood the test of time. Those who are acquainted with my other writings (on the aetiology and mechanism of the psychoneuroses) will know that I never offer unfinished work as finished, and that I have always endeavoured to revise my conclusions in accordance with my maturing opinions; but as regards the subject of the dream-life, I am able to stand by my original text. In my many years' work upon the problems of the neuroses I have often hesitated, and I have often gone astray; and then it was always the interpretation of dreams that restored my self-confidence. My many scientific opponents are actuated by a wise instinct when they decline to follow me into the region of oneirology.

Even the material of this book, even my own dreams, defaced by time or superseded, by means of which I have demonstrated the rules of dream-interpretation, revealed, when I came to revise these pages, a continuity that resisted revision. For me, of course, this book has an additional subjective significance, which I did not understand until after its completion. It reveals itself to me as a piece of my self-analysis, as my reaction to the death of my father, that is, to the most important event, the most poignant loss in a man's life. Once I had realized this, I felt that I could not obliterate the traces of this influence. But to my readers the material from which they learn to evaluate and interpret dreams will be a matter of indifference.

INTRODUCTORY NOTE (first edition)

But the very context to which our subject owes its importance must be held responsible for the deficiencies of the following chapters. The abundant lacunae in this exposition represent so many points of contact at which the problem of dream-formation is linked up with the more comprehensive problems of psycho- pathology; problems which cannot be treated in these pages, but which, if time and powers suffice and if further material presents itself, may be elaborated elsewhere.

The peculiar nature of the material employed to exemplify the interpretation of dreams has made the writing even of this treatise a difficult task. Consideration of the methods of dream- interpretation will show why the dreams recorded in the literature on the subject, or those collected by persons unknown to me, were useless for my purpose; I had only the choice between my own dreams and those of the patients whom I was treating by psychoanalytic methods. But this later material was inadmissible, since the dream-processes were undesirably complicated by the intervention of neurotic characters. And if I relate my own dreams I must inevitably reveal to the gaze of strangers more of the intimacies of my psychic life than is agreeable to me, and more than seems fitting in a writer who is not a poet but a scientific investigator. To do so is painful, but unavoidable; I have submitted to the necessity, for otherwise I could not have demonstrated my psychological conclusions. Sometimes, of course, I could not resist the temptation to mitigate my indiscretions by omissions and substitutions; but wherever I have done so the value of the example cited has been very definitely diminished. I can only express the hope that my readers will understand my difficult position, and will be indulgent; and further, that all those persons who
