During the time of cooperation with the surrealists, Dali had many new ideas and techniques, perhaps the most significant innovation was his “paranoid critical” method.
With this method, Dali analyzes double images in the “Paranoid Face” and “The Invisible Afghan”. Toward the end of the thirties, he was criticized by Andre Breton, the leader of the surrealist movement, for writing “puzzles” whose sole purpose was to get the viewer to decipher the images.
In the “Paranoid Face” the stone building resembles the head, the trees turn into thick hair, and the sitting people become eyes, nose and mouth. The picture is based on a picture depicting African villagers.
