A Streetcar Named Desire, Scene 11. Blanche’s increasing mental instability is highlighted by the distorted playing of the polka music associated with her husband’s suicide. Her deranged mental state is further suggested by the lurid reflections on the wall and jungle noises, all of which are in Blanche’s troubled mind.
