The old man said that dreaming about being bitten by a mouse is a bad omen. Does that make sense?

Auspiciousness and ominousness can only be known through practical testing. However, giving people some psychological hints in advance can play a certain guiding role in the development of things. Therefore, benign hints can play a benign guiding role, and dark hints can also play a misleading role. Therefore, if you want things to be positive, it is still necessary to engage in useful self-suggestion. Whether it is good or not depends on the individual's mentality and has little to do with the content of the dream. Dreams are mostly manifestations of the subconscious mind.
