"The Interpretation of Dreams" is a masterpiece by Sigmund Freud, the most widely known ideological master, and one of his most important contributions to psychology. This book provides a scientific psychological analysis of human dreams from the aspects of dream analysis methods, material sources, working principles, etc. Freud described it this way: "Insight such as this falls to one's lot but once in a lifetime" (Such an insight can only be obtained once in a lifetime by luck). This book, along with Darwin's "On the Origin of Species" and Copernicus's "On the Revolution of the Celestial Spheres", is one of the three major revolutions in human thought. It was reprinted eight times during the author's lifetime and translated into many languages and sold well all over the world. It is still very popular among readers today. As a symbol of the formation of the psychoanalytic theoretical system, it established a new milestone for human beings to understand themselves. It was like a torch that illuminated the way forward for psychological research. In 1956, it was listed as one of the "books that changed history" and "epoch-making and immortal masterpieces" by Dr. Downs of the United States in 1956.
