Sigmund Freud

Sigmund Freud (1856-1939), physiologist, medical doctor, psychologist and known as "the father of Psychoanalysis", is generally recognised as one of the most influential and authoritative thinkers of the twentieth century. One of his main contributions was to present dreams as sources of insight into unconscious, unconscious desires. In 1900, after a protracted period of self-analysis, he published The Interpretation of Dreams, which is generally regarded as his greatest work. Classically, the bringing of unconscious thoughts and feelings to subsciousness is brought about by encouraging the patient to talk in free association and to talk about dreams.
  

The dream is a fragment of the abandoned psychic life of the child.
  

That source is the unconscious. I believe that the conscious wish is a dream inciter only if it succeeds in arousing a similar unconscious wish which reinforces it.
  

It is interesting to note that they are right who regard the dream as foretelling the future. Although the future which the dream shows us is not that which will occur, but that which we would like to occur.
  

The formula for these dreams may be thus stated: They are concealed realizations of repressed desires.
  

Moreover, dreams are so intimately bound up with language that Ferenczi truly points out that every tongue has its own language of dreams. A dream is as a rule untranslatable into other languages.
  

The dream does never trouble itself about things which are not deserving of our concern during the day, and trivialities which do not trouble us during the day have no power to pursue us whilst asleep.
