A man was being tormented by daily nightmares. What specific advice did a Sai devotee give him, and what was the outcome?

In an account from Chapter 35, a man from Bandra suffering from daily nightmares was advised by a Sai devotee. The devotee expressed that they knew no other remedy but the great soul, Lord Sai, and suggested that if the man kept faith, the Udi would manifest its influence. The specific instructions were twofold: first, to apply a little Udi to his head when going to sleep, and second, to tie a packet of Udi and keep it under his pillow. He was also told to remember Shri Sai in his mind with devotion. The outcome was immediate and profound. As soon as he followed this advice, he fell into a deep sleep that very night, the bad dreams were erased, and the gentleman was very happy.
