Is it normal to dream about grocery stores?

Recently I've started to notice that many of my dreams take place in grocery stores. Even thinking back, a lot of my most vivid dreams were the ones that were set in a grocery store. They aren't necessarily the stores that I go to, they're just a general grocery store. Sometimes the dream revolves around me having to find certain food items for some sort of event, and other times I spot an acquaintance and have to hide from them (I usually do this when I'm at the grocery store in real life, I have social anxiety...). However, for the past two nights I've been dreaming about finding the jewelry department in wal-mart. In the dream I start to panic because I cannot find the jewelry department. Last night I ended up finding the jewelry department and began searching for something that would go with what I was wearing. I ended up finding blue dangle earings. It was really weird because I never wear earings, nor would I want to. I know dreams are never actually what they appear to be about. So does anyone have any idea why I would keep dreaming these things?
And is there anyone else who has similar dreams??
