I believe that dreams are a message from the unconscious that is trying to help us by making us aware of things that for the moment are sitting outside our conscious awareness. This feeling you have of the entire universe being against you is a conscious or ego-based orientation. But the dream wants to give you a more specific message, I believe, that is meant to help you move forward.

What I observe in the dream is that it is after your mother scolds you that you regret summoning the demon. This suggests that it's something about your relationship with your mother that prevents you from staying with your feelings. It is up to you to decide if that interpretation feels right, but I will just note that the dream is not saying the same thing as your conscious orientation. There is nothing in the dream about the entire universe being set against you.
