Calderon de la Barca’s Life is a dream is the most representative baroque theatre that expresses the Baroque world most symbolically. This play, written in Baroque period, shows the most distinct baroque tendencies both in style and content. This paper comprehensively examines the aspects of various baroque features inherent in the content dimensions of Life is a dream. This paly shows Baroque characteristics in terms of breaking the boundary between dream and reality, identity confusion, constantly affluent subject, overturning gender roles, uncertain world, skepticism about human existence, and overturning of intellectual roles. Interestingly, however, even though this play shows the Baroque spirit and the most Baroque feature, the Baroque, which attempted to deviate from the Renaissance and overthrow it, eventually failed, and his new subversion pattern was incorporated into the existing stable order. This is the Calderon de la Barca’s political and social commentary on Spain’s baroque society. The author offers the solution to the baroque chaos. His solution is the restoration of reason-based morality and social order. Segismundo, the protagonist, realizes and practices the need to overcome confusion through rational and moral actions through the device of dream. So the protagonist, who won the battle against his father, forgives and embraces his father, restores the honor of Rosaura, and punishes the soldiers who have overthrown the political order in order to establish the order that had been thrown into confusion for a while. Ultimately Calderón de la Barca suggested a way to restore stability and order in society by overcoming uncertainties and confusion in the 17th century through "Life is a Dream."
