"Out, damned spot; out, I say" A5S1 Lady Macbeth
-Obsessive washing of her hands relates to and contrasts "A little water clears us of this deed". Hypocrisy
-The anaphora "Out" displays how haunted she is. Washed away the blood but can't wash away the psychological stain on her conscience.
-Also, her need to "have light by her continually" displays her fear of the silent dark which forces her to face her "infected mind"
