What happened to the Patil in his dreams, and what was the ultimate result of these experiences?

In Chapter 13, the Patil experienced two strange and distressing dreams. In the first, a teacher beat him with a cane, breaking his back, to make him memorize a verse. In the second, a gentleman sat on his chest and used a grinding stone on him. Despite the agony of these dreams, the result was miraculous. When the Patil woke up, he felt an unprecedented freshness, his disease had vanished completely, and he felt as though he had been reborn. The punishment he endured in the dream was ultimately beneficial, leading to his complete healing.
