I guess I'll offer something germane to the OP. I am sure most of us who practice with any dedication for a few years will have some dream experiences, and it can be very difficult to suss out what is wisdom and what is mind. I've had a number of dream experiences that - mind or not - have given me a very real and needed boost of devotion and faith, inspiraration. Here's one:
About eighteen years ago I was reading Dilgo Khyentse Rinpoche's book on Paltrul's commentary on the Mani mantra. It was a warm CO afternoon, and I dropped the book for a lil' napperooski.[I should insert that even though I've been playing with dream yoga for many years I've never accomplished anything real. I have also never met Dilgo Khentse Rinpoche, though a number of my teachers have a strong connection with him.]
So, I'm dreaming that I'm in this long line of students with scarves, waiting for a moment with the guru, a very real sense of the time it takes to get through the line... arrive in front of DKR, and it's as though he's taking questions. I look at him, he looks at me, smiles, asks, "Yes?" I think about all of the detailed questions I want clarified, and they all are somehow answered in their own asking, rooted in the earth, and the "earth," ground, holds the pieces of the question/answer zygote. I'm flooded with a sense of wholeness and calm, fulfillment, wanting to share. Every question comes from its own answer somehow. I'm amazed at the fullness of some crazy cosmic wisdom, look back at him, still smiling, and then I become hyper-aware at all of the longing and anxious people behind me in line waiting for some "answer." Look back, he's still smiling, almost teary-eyed, and I feel this sense of being before a real bodhisattva tirelessly giving nothing to no one for no reason, and making a difference.
It shocks me awake, and I pick up the half-open book on my mattress, the back cover of which has DKR with that same wide-open, bottomless, cosmic smile. He's in the room, there is no "walls," looking at me. I try to hold onto the feeling... it slips into "mind," but it still made for a very refreshing afternoon.
I have been told by students of DKR that he often showed up in there dreams. I believe them.
