Begging the Duke of Zhou to take a nap, I dreamed that a long earthworm wrapped around me and somehow slipped away from my leg.

Hello, according to the meaning of Huangdi Neijing, it is mostly a manifestation of yin deficiency. Due to yin deficiency, insufficient yin essence and insufficient yin essence, the lungs cannot deliver enough yin fluid to the skin. It caused the skin to lack sufficient nutrition and moisture, which made the skin itchy, so I had a reaction in my dream, turned into an earthworm wrapped around me, and then somehow slipped away from my leg.
