"The Dream, a Life", Grillparzer's technical masterpiece, is in form perhaps even influenced by Spanish drama; it is also more of what Goethe called a confession. The aspirations of Rustan, an ambitious young peasant, are reflected in the hero's dream, which takes up nearly three acts of the play. Ultimately Rustan awakens from his nightmare to realize the truth of Grillparzer's own pessimistic belief that all earthly ambitions and aspirations are vanity; the only true happiness is contentment with one's lot and inner peace. It was the first of Grillparzer's dramas that did not end tragically. Grillparzer provided the text for Schubert's 'Mirjams Siegesgesang' (Miriam's Song of Triumph), Op. 136/D. 942.
