Can you explain the strange dreams the Patil had in Chapter 13 and what they ultimately signified for his faith?

In Chapter 13, the Patil experienced two distressing dreams. The first involved a teacher beating him with a cane, and the second featured a gentleman crushing his chest with a grinding stone. Initially, these experiences were terrifying, causing him immense agony. However, upon waking, the Patil found that his disease had vanished and he felt an unprecedented freshness. The text notes that while dreams are often seen as illusions, in this case, the opposite reality appeared. These dreams, though painful, were the instruments of Sai Baba's grace, leading to the Patil's healing. This miraculous event solidified the Patil's faith, filling him with immense joy and gratitude towards Sai for his unconventional but ultimately benevolent intervention.
