Can you describe the strange dream the Patil had in Chapter 13 and what happened when he woke up?

In Chapter 13, the Patil experiences a very unusual two-part dream that ultimately leads to his healing. In the first part, a teacher punishes him with a cane for failing to memorize a verse. Immediately following this, a second, stranger dream occurs where a gentleman sits on his chest and uses a grinding stone as a mortar, causing him extreme agony. Despite the terrifying nature of these visions, the outcome was miraculous. As Chapter 13 recounts, when the Patil woke up, he felt an unprecedented freshness, and the idea of his disease had vanished completely. The dream, though an illusion, brought about a real destruction of his illness and relief from his sorrow.
