According to the source text, in what ways would Sai Baba interact with his devotees in their dreams?

As detailed in Chapter 28, Sai Baba would often appear in his devotees' dreams to guide them and give them his darshan, especially when they were far away. The chapter provides several examples of these divine plays, noting that he might ask for khichdi from one devotee, or take a stick and beat another's back in the instructive manner of a Guru. It is also mentioned that he would appear in dreams to help break followers' addictions to substances like liquor, thereby removing their troubles and fostering a deep love for his holy feet.
