"The Interpretation of Dreams" is Freud's masterpiece; published in 1900. In this book, the author cites a large number of dreams as examples and carefully discusses dream-related issues from all aspects. He made the following observations.

1. Dreaming is a spiritual activity; "its motivation is often a desire to seek satisfaction." Dreams arise from wishes, and their content is "the fulfillment of wishes." Dreams not only give opportunities for thoughts to express themselves, but also express the satisfaction of wishes through hallucination experiences. The author cites many examples regarding dreams as "fulfillment of wishes." One of them was a dream of his 5-year-old son. Once, their family went to play at the foot of Mount He. The younger son was not satisfied with playing at the foot of the mountain because he could see Simone's hut on the mountain through his telescope. But his parents did not take him up the mountain, and he was not very happy at the time. The author said: "The next morning, he ran over to me in high spirits and told me; 'Last night I dreamed that we walked through the temple and reached Simone's hut.' I now understand that when I said I wanted to go to Dach Mountain, he He fully thought that he would be able to walk over the mountains from Holstatt to the Simone cabin that he longed for with his telescope every day. But once he learned that he could only end at the waterfall at the foot of the mountain, he was so disappointed. It was so unsatisfactory. But the dream compensated him."

2. Dreams are the self-expression of the subconscious. The subconscious is suppressed in the deepest part of the human heart, but it is very active. The plan is to break through the realm of preconsciousness and emerge. When the "self" needs to rest but cannot get complete rest, that is, the "self" is in a state of confusion and relaxes its guard, the subconscious mind begins to act, and dreams appear. Because many of the dreams of the dreamer are contrary to wishes Moral, so the subconscious appears in a disguised form. The reason why dreams are strange and incomprehensible is that dreams have been disguised many times and must be interpreted through psychoanalysis.

< p>3. Freud believed that dreams and mental illness are similar. He believed that "dreams contain a brief psychology of neurosis" because he was based on the theory of the subconscious when interpreting dreams and neurosis. He concluded that both dreams and mental illness are in line with the laws of subconscious activity, and concluded: "The subconscious prefers to be related to those concepts in the preconscious that are unnoticed, ignored, or have just been relegated to the cold side (ostracized). . "Through this method, the cunning subconscious can sneak into the realm of consciousness. Freud denied that people in the past said that dreams are revelations from supernatural ghosts and gods, emphasizing that dreams are part of human psychological activities and come from Subconscious.

Dreams are neither the manifestation of the soul nor the revelation of God, but the condensation and sedimentation of human practice in the early years.
