The alliteration of "day," "droop," and "drowse" does not support the idea of Macbeth's exhaustion, preference for evening activities, or the emphasis on the end of the day as a time of good deeds. Instead, it supports the idea that the night is like a predator chasing its prey, which contributes to the sinister mood in this part of the text. The alliteration creates a sense of repetition and monotony, which reflects the feeling of being trapped or pursued by something ominous or threatening. The use of these particular words - "day," "droop," and "drowse" - also suggests a sense of weariness and fatigue, which further contributes to the ominous tone.
