"Hannele: a double-ended sonnet-tale" is a famous work of the German writer Gerhard Hauptmann. This drama tells the story of a girl, Hannele, who feels alienated from the world of adults. She escapes into the world of imagination, where she finds refuge from reality. In this sleepy fairytale world, she meets various characters who symbolize different aspects of human nature and society. Hannele is looking for her place in life, striving to understand her true nature and learn the truth about the world. Each episode of the work is permeated with philosophical thoughts and reflections on the importance of dreams, imagination and self-discovery. This sophisticated theatrical work not only tells Hannele's story, but also forces the reader to delve into his own reflections on the meaning of life, loneliness and inspiration. Hauptmann successfully combined dreaminess, symbolism and social criticism in this play, which makes "Hannele" an outstanding work of world literature.
