Answer: The speaker's use of personification supports the theme of the poem that death is actually a spiritual rebirth and therefore should not be feared.
Step-by-step explanation:
In 'Because I Could Not Stop for Death', Emily Dickinson explores the theme of death from a quite unusual perspective. In the poem, Death is personified and not as frightening as people often consider it. He is a gentle guide that arrives in his carriage to accompany the speaker on her journey to afterlife. Death is patient and drives the carriage slowly, which demonstrates that he cares for the speaker's emotions. As a result, instead of being frightened by Death, the speaker enjoys the ride.
