From 1920 on, artists tried more experimental ways to express themselves. Emerged out of Dada movements during World War 1, affected by Freudian psychoanalysis, Surrealism focused on the unconscious mind and allowed it to express itself through artworks. Coincidental forms are modified to draw attention to free associations. Andre Masson, Max Ernst, Salvador Dali, René Magritte revolutionized the perception of the viewer through surprising juxtapositions.
