What happened to the Patil in his dreams as described in Chapter 13, and what was the miraculous result?

Chapter 13 recounts the story of a Patil suffering from a disease who experienced two very strange and troubling dreams. In one, a teacher punished a student with a cane, and in the second, a gentleman pressed on the Patil's chest with a grinding stone, causing immense agony. However, as the narrative explains, upon waking, the Patil felt an unprecedented freshness and discovered that his disease had vanished completely. Though people often call dreams an illusion, the chapter highlights that in this case, the opposite was true, as the dream led to the "destruction of the disease and relief from sorrow" for the Patil, who felt he had been reborn.
