Summary bài này với ạ T_T Sigmund Freud is regarded as the founder of psychoanalysis. His work has been influential in many areas but he is perhaps best known for having drawn our attention to dreams, which he believed were clues to inner conflicts. The fact that a dream is essentially a disguised expression of what is happening in the unconscious mind means that it is difficult for the dreamer to understand its significance. Freud believed that the sleeping mind resorted to a whole range of unconscious wishes in forms which would prevent the dreamer from having any awareness of their true nature.
