What is your subconscious telling you—and why? In his groundbreaking 1899 work, the founder of psychoanalysis, Sigmund Freud, explores the mysteries of dreams. According to Freud, dreams are puzzles to be solved, with their manifestations of everything from long-forgotten memories to unspoken, hidden desires.

Including dozens of case histories and detailed dream analyses, The Interpretation of Dreams remains a fascinating and revealing exploration of the vast and enigmatic human mind.

Revised edition: Previously published as The Interpretation of Dreams, this edition of The Interpretation of Dreams (AmazonClassics Edition) includes editorial revisions.

Building on the crucial insight that jokes use many of the same mechanisms he had already discovered in dreams, Freud developed one of the richest and most comprehensive theories of humour that has ever been produced.

Jokes, he argues, provide immense pleasure by allowing us to express many of our deepest sexual, aggressive and cynical thoughts and feelings which would otherwise remain repressed. In elaborating this central thesis, he brings together a dazzling set of puns, anecdotes, snappyone-liners, spoonerisms and beloved stories of Jewish beggars and marriage-brokers. Many remain highly amusing, while others throw a vivid light on the lost world of early twentieth-century Vienna.

One of Freud's central achievements was to demonstrate how unacceptable thoughts and feelings are repressed into the unconscious, from where they continue to exert a decisive influence over our lives.

This volume contains a key statement about evidence for the unconscious, and how it works, as well as major essays on all the fundamentals of mental functioning. Freud explores how we are torn between the pleasure principle and the reality principle, how we often find ways both to express and to deny what we most fear, and why certain men need fetishes for their sexual satisfaction. His study of our most basic drives, and how they are transformed, brilliantly illuminates the nature of sadism, masochism, exhibitionism and voyeurism.

This volume brings together Freud's main contributions to the psychology of love. His illuminating discussions of the ways in which sexuality is always psychosexuality - that there is no sexuality without fantasy, conscious or unconscious - have changed the ways we think about erotic life. In these papers Freud develops his now famous theories about the sexuality of childhood and the transgressive nature of human desire.

In the famous case study of the eighteen-year-old 'Dora', we see Freud at work, both putting into practice and testing his sexual theories that were to change the modern world.
