&quot;Dream Psychology&quot; (also known as &quot;<i>Dream Psychology - Psychoanalysis for beginners&quot;)&nbsp;</i>was first published in 1921. It is a definitive work which changed the climate of treatments and handling of different neuroses and dysfunctional people. The book is divided into nine chapters. In many of them, Sigmund Freud uses his own dreams as subjects for interpretation, while in others, he uses his patients&#39; dreams to elucidate his theories of psychoanalysis. While some of the theories may no longer be relevant or valid in today&#39;s world, this book is indeed one of the foundation stones of Freudian psychoanalysis and marked a water-shed in the attitude towards dreams. He refuted the purely medical and purely spiritual interpretations that had been prevalent till then and proposed a completely new theory.
