Dreaming about snakes is also an inductive dream. A snake represents a creditor who has been wronged for generations. It may have killed or hurt it. Because it is willing to make peace with you after listening to the classics, it appears in the dream. Otherwise, if you are determined to take revenge, you won't be exposed.
I suggest that you return to it in your dream after singing. May it take advantage of this merit, settle grievances with you, go to bliss or goodness, and get pleasure from suffering.
