Can you describe the bizarre dreams the Patil experienced and what happened to him immediately after waking up?

In Chapter 13, the Patil experienced two consecutive dreams that were quite strange and violent. In the first, a teacher was brutally caning a student to make him memorize a verse. Immediately following this, in a second dream, a gentleman sat on the Patil's chest and used a grinding stone to make a mortar of it, causing him such agony that he felt his life was ending. However, upon waking, the outcome was the complete opposite of the dream's horror. The Patil felt an "unprecedented freshness," and his disease had vanished completely, with no physical marks left from the cane or grinding stone. This event, as described in the chapter, left him feeling as though he had been reborn.
