Personification is giving human characteristics, feelings and actions to animals, non-animate objects and ideas. It is a form of metaphor.
In this illustration, death is presented as the grim reaper, Death, who is wondering whether s/he has the right house.
There are so many examples of personification in literature: the arms of willow trees hang to the ground; the sun races across the sky; ship hulls plough the sea; stars hide their fires; Winter rides through the woods; Frost calls, ‘Halt!’
By the way – and absolutely nothing to do with personification or death – just a word on the gender of reapers (above) : women definitely wielded the scythe in times gone by. Here is some literary evidence from the first verse of Wordsworth’s ballad The Solitary Reaper, written on 1805:
