Pentru Sigmund Freud, analiza, cu aparat psihanalitic, a viselor faciliteaza, in primul rand, descifrarea misterului afectiunilor nevrotice si, in al doilea rand, deschide drumul spre inconstient, visul fiind den koniglichen Weg (calea regala) spre inconstient. Freud distinge trei tipuri de vise diferentiate in functie de gradul de rationalitate si de veridicitate a continutului. In prima categorie se situeaza visele simple sau visele clare, care sunt specifice copiilor si care sunt inspirate de nevoi fiziologice. In cea de-a doua categorie sunt situate visele rezonabile, care au o anumita coerenta logica, iar in cea de-a treia categorie sunt visele obscure, incoerente si absurde, care trezesc interesul psihanalistilor. Freud declara in Despre vis ca In realitate, travaliul visului este primul proces cunoscut dintr-un intreg sir de procese psihice, in special cele din care se deduce aparitia simptomelor isterice, a angoaselor, a obsesiilor, a ideilor delirante etc . Visele reprezinta imaginarul constient, deoarece producerea si dezvoltarea lor excedeaza controlul voluntar, iar apartenenta acestora la imaginatie se sustine prin doua prin continutul lor, care vizeaza fenomene si evenimente ireale, si prin faptul ca, desi au origine in experienta anterioara, modul de combinare a secventelor e inedit, acestea nefiind simple reproduceri a ceea ce s-a intamplat. Colectia Canapeaua lui Freud va invita la o ora de lectura formativa. Intalnirea cu cartile din aceasta colectie nu va fi neaparat comoda, dar ideile, argumentele, disputele pe care le contin va vor deschide noi orizonturi; va vor oferi modele de interpretare a psihicului uman.
Dr. Sigismund Freud (later changed to Sigmund) was a neurologist and the founder of psychoanalysis, who created an entirely new approach to the understanding of the human personality. He is regarded as one of the most influential—and controversial—minds of the 20th century.
In 1873, Freud began to study medicine at the University of Vienna. After graduating, he worked at the Vienna General Hospital. He collaborated with Josef Breuer in treating hysteria by the recall of painful experiences under hypnosis. In 1885, Freud went to Paris as a student of the neurologist Jean Charcot. On his return to Vienna the following year, Freud set up in private practice, specialising in nervous and brain disorders. The same year he married Martha Bernays, with whom he had six children.
Freud developed the theory that humans have an unconscious in which sexual and aggressive impulses are in perpetual conflict for supremacy with the defences against them. In 1897, he began an intensive analysis of himself. In 1900, his major work 'The Interpretation of Dreams' was published in which Freud analysed dreams in terms of unconscious desires and experiences.
In 1902, Freud was appointed Professor of Neuropathology at the University of Vienna, a post he held until 1938. Although the medical establishment disagreed with many of his theories, a group of pupils and followers began to gather around Freud. In 1910, the International Psychoanalytic Association was founded with Carl Jung, a close associate of Freud's, as the president. Jung later broke with Freud and developed his own theories.
After World War One, Freud spent less time in clinical observation and concentrated on the application of his theories to history, art, literature and anthropology. In 1923, he published 'The Ego and the Id', which suggested a new structural model of the mind, divided into the 'id, the 'ego' and the 'superego'.
In 1933, the Nazis publicly burnt a number of Freud's books. In 1938, shortly after the Nazis annexed Austria, Freud left Vienna for London with his wife and daughter Anna.
Freud had been diagnosed with cancer of the jaw in 1923, and underwent more than 30 operations. He died of cancer on 23 September 1939.
