  • The Ghost Sonata is a 1907 play in three acts by Swedish playwright August Strindberg.
    • It is about "a young student, who idealizes the lives of the inhabitants of a stylish apartment building in Stockholm. He makes the acquaintance of the mysterious Jacob Hummel, who helps him to find his way into the apartment, only to find that it is a nest of betrayal and sickness. The world, the student learns, is hell and human beings must suffer to achieve salvation. The play centers on a family of strangers who meet for the sake of meeting ... they simply sit and bask in their own misfortune."[5]
