Life Is a Dream (Spanish: La vida es sue�o) is a play by Pedro Calder�n de la Barca. It was first published in 1635. The play is a philosophical allegory regarding the human situation and the mystery of life. It has been described as "the supreme example of Spanish Golden Age drama". The story focuses on the fictional Segismundo, Prince of Poland, who has been imprisoned in a tower by his father, King Basilio, following a dire prophecy that the prince would bring disaster to the country and death to the King. Basilio briefly frees Segismundo, but when the prince goes on a rampage, the king imprisons him again, persuading him that it was all a dream.
