This book is a detailed analysis of the most famous dream in the history of psychoanalysis - “On the Injection of Irma.” It was the analysis of “Irma” that allowed Freud to deduce the main provisions of his oneeurocriticism and write the Bible of psychoanalysis – “The Interpretation of Dreams”, and Lacan to formulate his attitude towards sleep, dreams, and reality. The author of the book, the famous psychoanalyst Viktor Mazin, following the logic of Lacan, deconstructs one of the fundamental oppositions of Western metaphysics - the opposition of dreams and reality, outlining the main provisions of psychoanalytic oneirocriticism. The publishing layout of the book is saved in PDF A4 format.
