Among the first of Sigmund Freud's many contributions to psychology and psychoanalysis was The Interpretation of Dreams, published in 1900, and considered his greatest work — even by Freud himself. Aware, however, that it was a long and difficult book, he resolved to compile a more concise and accessible version of his ideas on the interpretation of dreams. That shorter work is reprinted here. Since its publication, generations of readers and students have turned to this volume for an authoritative and coherent account of Freud's theory of dreams as distorted wish fulfillment. After contrasting the scientific and popular views of dreams, Freud illustrates the ways in which dreams can be shown to have been influenced by the activities or thoughts of the preceding day. He considers the effect on dreams of such mental mechanisms as condensation, dramatization, displacement, and regard for intelligibility. In addition, the author offers perceptive insights into repression, the three classes of dreams, and censorship within the dream. Students and psychologists will welcome this inexpensive edition of an always-relevant work by the father of modern psychoanalysis. This volume will also appeal to anyone interested in dreams of the workings of the unconscious mind.
