What philosophical perspective on dreams is presented in the story of the Patil?

Chapter 13 presents a fascinating perspective on the nature of dreams. The text explicitly states, 'People call dreams an illusion, but sometimes the opposite reality appears.' In the Patil's case, he experienced terrifying dreams, including one where his chest was made into a mortar. While these events were dream-illusions, they had a tangible, real-world effect. Upon waking, the Patil found his disease was gone and his sorrow relieved, as if he had been reborn. This suggests that in the realm of faith and Sai's grace, the boundary between dream and reality can blur, and events in the dream world can manifest as profound, beneficial changes in one's physical reality.
