The personification involves treating an abstraction, such as death or justice or beauty, as if it were a person. When ˇ°That time of yearˇ± talks about the coming of night and of sleep, for example, Sleep is personified as the ˇ°second selfˇ± of Death (that is, as a kind of ˇ°doubleˇ± for death [line 8]). 

If personification in this poem is a brief gesture, it proves much more obvious and central in Dickinson's poem, though in this case, too, it is death that the poet personifies. 

How so, and with what implications and effects? What vision of death and the afterlife is implied by the way death is personified and characterized in the poem? by the details the speaker offers about the carriage ride she takes with him?
