8"Dream Psychology," by Austrian neurologist Sigmund Freud was first published in 1920. Sigmund Freud's book explains how to interpret dreams and in doing so, unlock the hidden desires of the mind and our true nature as human beings. Freud argues all dreams hide an inner meaning or some deep desire of the subconscious. Every dream has a connection to reality, where what one does, thinks, and feels in a day has a direct impact on their dreams. Having introduced the theory of the Oedipus Complex and other ground-breaking psychological theories in this work, "Dream Psychology," was a fundamental book for Freud's career as it established him as the founder of psychoanalysis. Though it took over eight years to gain momentum, Freud's "Dream Psychology" has remained a fundamental work in the study of dream analysis for over a century.
