Grocery Store Injury

I don't remember many details of this dream but my husband and I were living in the back of a grocery store. The store was old and not very big with exposed concrete floors, older equipment, and a disjointed layout. One day while walking through the store, I was barefoot and stepped on something. We stopped to look at my foot and found a large plastic 'toothpick' stuck in my heel (it was shaped like a sword, the kind sandwich shops use to keep a club sandwich together or the wrapper on the sandwich). My husband pulled it out of my foot and it was covered in blood and goo. I hobbled around the store with him looking for juice. That's all I remember.
