What is the meaning of unpacking a grocery shop?

What is the meaning of unpacking a grocery shop in "here’s a line in a Mary Oliver poem which asks “What is it you plan to do with your one wild and precious life?” and has been living rent-free in Emilie’s head since she happened upon it, earlier in the year. It echoes over and over again every time she empties a dishwasher, wakes at 3am, streams an episode of Bridgerton, unpacks a grocery shop. It’s the unwelcome guest in her living room, the one who lingers rather than leaving, a bit drunk and slurry. Emilie has been driving Annabel mad with it, because she wants someone else to tell her what she is for; someone else to provide an answer compelling enough to exorcise her Mary Oliver haunting. All this to say, we understand, Adrift."?
