The surrealist art movement focused on expressing the subconscious mind through techniques like automatism. Inspired by Freudian psychology, surrealists believed dreams and hypnosis could reveal the subconscious. There were two main types: automatism, which used images without interpretation to express subfeelings, and veristic, which saw images as metaphors to understand the subconscious. Major surrealist artists included Salvador Dali, Joan Miro, and Max Ernst, who employed surrealist techniques to create dreamlike and bizarre works exploring the mind.
