Can you describe the strange dreams the Patil had in Chapter 13 and explain their outcome?

Chapter 13 details two consecutive and bizarre dreams experienced by the Patil. In the first, a teacher beat him with a cane, determined to make him memorize a verse. Immediately following this, he had a second dream where a gentleman sat on his chest and used a grinding stone upon it like a mortar, causing him extreme agony. Despite the terrifying nature of these dreams, the outcome was miraculous. As Chapter 13 recounts, when the Patil woke up, he felt an "unprecedented freshness" in his mind, and his disease had "vanished completely." He realized that what seemed like a punishment in the dream was actually a beneficial act of grace from Sai that resulted in the complete destruction of his ailment and relief from his sorrow.
