Dream About Shopping Center Incident

This dream was about

This dream took place in some kind of large shopping center. The first store I went to contained a scene in which people were all buying the same things . (Milk and something else I can’t remember) Apparently, they were all buying milk because they were from a theatre class and they were cooking some kind of pastry that went wrong. I ended up joining them and buying the milk too for whatever reason. I then go to another store for some reason carrying the goriceries from the previous one with me. My mom is there as well strangely enough but I do most of the shopping. I even get angry when my mom tries to buy me a pizza as it wasn’t the right flavor. Anyways, as I go to the checkout line, the people there are suspicious as to what the groceries already in bags were. I tell them that they were from a previous store in which everybody was buying the same thing. They then take me to some kind of back room and question me further. I tell them that it was due to some kind of incident with a theatre class. For some reason, they know what I’m talking about and leave to investigate. This is where the dream ends for the most part.
