Let's theorize here for a minute: what would you do?

A friend of mine had a dream and in the dream the shelves at the store were empty with only one or two items per shelf. There were no supplies to be purchased. She is very spiritual and felt that this dream was prophetic. I know that it is already financially hard for me and my family. I shudder to think what will happen if things come to that. I find it too terrifying to dwell on.
