[Lurid reflections appear on the wall around Blanche. The shadows are of a grotesque and menacing form. She catches her breath, crosses to the phone and jiggles the hook. Stanley goes into the bathroom and closes the door.]
– Tennessee Williams
A Streetcar Named Desire, Scene 10. The stage directions paint a vivid picture of Blanche’s fear when Stanley verbally attacks her and goes into the bathroom. She also hallucinates and sees "lurid reflections" and "grotesque and menacing" shadows on the wall. This use of light imagery reflects Blanche’s descent into madness.
