In the story “old man of the temple” by r. k. narayan, what experience does the narrator have in the taxi on his way to kumbum?

He had a supernatural experience during his ride in the taxi as the old man’s spirit possessed the taxi driver.  The old man’s spirit refused to believe that he was dead until the main character was able to prove otherwise.  In the end, the old man accepted the truth and the knocking at the temple stopped.

as for symbolic actions, the narrator's tearing down the wallpaper in an attempt to find the "woman" in the wallpaper represents her struggle to retain or regain her sanity.   the wallpaper has been part of her confinement and by her tearing it down, she is freeing herself from that confinement.
