Can you describe the strange dreams the Patil experienced in Chapter 13 and their immediate effect on him?

In Chapter 13, the Patil experienced two very strange dreams orchestrated by Sai Baba. In the first, he saw a teacher harshly punishing a student with a cane just to make him memorize a verse. The second dream was even more bizarre; a gentleman sat on his chest and used a grinding stone on it like a mortar, causing him immense agony. Despite the terror of these visions, when the Patil awoke, he felt an unprecedented freshness, and his disease had vanished completely. The narrative notes that while people often dismiss dreams as illusions, in this instance, the opposite reality appeared, leading to the destruction of his illness and relief from his sorrow.
