The first years of the 1900s were a massive flood of art, literature, philosophical and political thought. Society was driven by their interest to explore and invest further. One person who shaped this time a lot was an Austrian guy called Sigmund Freud—he was a neurologist and the founder of psychoanalysis. In many of his writings, he reflected on the human being and what is going on inside our brain. Today he is famous for his associations with dreams and their meaning, but back then, he was starting a little rebellion, when more people learned through him about higher forms of truth are to be discovered in the unconscious.
