Direct psychoanalysis:
Because snakes are related to sex, it implies unsolved problems or fear of sex.
Fear in dreams is often the result of long-term accumulation of fear and doubt. Maybe Dream is ready to face these fears and doubts, because he is experiencing intense torture. That's why I screamed.
Zhou Gong analysis:
Snakes are dragons by birth, and dragons are symbols of wealth. Water represents wealth. Dragons soar in the water and tigers leap in the mountains. It is estimated that you will be happy, maybe a dragon, and you will be happy for a while. Dreaming that the snake will bring lucky things in reading, the book says so. If you don't belong to the same family, please ask Han Hai.
