Which movement, embracing the irrational and dreams, emerged in the 1920s and 1930s?

Surrealism

Surrealism, born out of the post-war era, merged art and literature to explore the depths of the human mind. André Breton, its principal theorist, saw in this movement a revolt against oppressive rationality, paving the way for the expression of subconscious thoughts. Surrealist works, often strange and dream-like, seek to transcend everyday reality by invoking the imaginary and the fantastical. This movement profoundly influenced literature and visual arts, encouraging an unrestricted exploration of human experience.
