The Research Of Displacement And Condensation In All Kinds Of Unconscious Forms

Under the flag of " Return to Freud " of Lacan, with the piety to Freud's works, by using the formula that Lacan mentioned later " all kinds of unconscious forms arecontrolled by the same structure as language's——metaphor and metonymy",through the clue that displacement is similar to metonymy and condensation is similar to metaphor ,this text begins to reread the Freud's previous works, has analyzed concretely unconscious composition forms dream, symptom , jokes and parapraxis that Freud had put forward, in order to know clearly the unconscious operation mechanism in all kinds of unconscious forms and enrich the unconscious theory better.This text divides into two levels. My first task is to prove that displacement and condensation exist in all unconscious composition forms. My second task is to explain how the displacement and condensation are worked and formed in them.
