How does the author use foreshadowing in The Grave?

Miranda's grandmother moves from place to place after her husband's death, and with each subsequent move, she uproots her dead husband's coffin to bring it with her. When she dies, she wants to be buried next to him. In the description of her moving, the narrator says it is as though the grandmother moved around looking for her own burial spot. This is symbolic to the idea of a restless woman who is looking for a final place to settle and rest. This also foreshadows Miranda adulthood; she too moves around in exploration of exotic places.
