Dreaming about shops

I keep dreaming about shops, malls and markets, I experience it almost every night. For example, a couple of days ago I dreamt I was running through a mall with a toothbrush in my mouth, looking for something. It seems to be more about shops in general than the products in it, in the dream mentioned above I was in a store filled with clothes, but yesterday I dreamt that I was sitting in a shopping cart in a bookstore. I'm having these dreams for two weeks now, always a different store, different products. I'm never really sure what I'm looking for or why I'm there.

What is the meaning of this?
