In dreams, people may experience all kinds of things, including good and bad. These experiences may have an impact on people's psychology and lead to some strange experiences in dreams. Therefore, it is only a psychological phenomenon that a person dreams of fighting with ghosts and beating them away in the Mid-Autumn Festival, which cannot be used as a basis for judging whether they are good or bad.
In short, don't be overly superstitious, but seek happiness and success in your own efforts and practical actions.
