Hypnagogic Images. From Algol to Dau al Set. After the Spanish Civil War, Brossa returned to Barcelona in 1940, where he read a great deal of Freud and, interested in psychic automatism, started to produce hypnagogic images. He met the poet J. V. Foix, who recommended that he experiment with the sonnet. He became friendly with Joan Prats who gave him free access to his specialist library of books on modern art. The acquaintance with Joan Miró was to be decisive in his ethical and aesthetic conception of literary and visual creation. Also in 1941, inspired by the work of Apollinaire, Salvat-Papasseit and Junoy, he wrote his first calligrams -which he called experimental poems- . In 1943 he picked up a piece of bark, a genuinee objet trouvé; this became his first object poem. In 1944, driven by the inner need to give a fourth dimension to the poem, he wrote his first stage work, El cop desert (Desert Stroke), which reflects his reading of Mallarmé and Nietzsche. In 1947, together with Joan Ponç, Arnau Puig, Jordi Mercader, Francesc Boadella and Enric Tormo, he founded the magazine Algol, which folded after only one issue. He wrote the first performance actions of Postteatre (1946-1962). In 1948, with Joan Ponç, Antoni Tàpies, Modest Cuixart, Arnau Puig and Joan-Josep Tharrats, he founded the magazine Dau al Set, with a spirit close to neosurrealism. In 1948 he also wrote the film scripts Foc al càntir (Fire in the Water Jug) and Gart.
