What happened in the Patil's dreams in Chapter 13, and what was the immediate result upon waking?

In a strange sequence of events described in Chapter 13, a Patil experienced two dreams. In the first, a teacher was harshly caning a student to make him memorize a verse. The second dream was even more bizarre: a gentleman sat on the Patil's chest and used a grinding stone on it, causing him immense agony. However, despite the suffering in these dreams, the outcome was miraculous. Upon waking, the Patil felt an unprecedented freshness in his mind, and his disease had completely vanished. The text notes that at that very moment, the disease was destroyed, providing him immense relief and satisfaction.
