The cause is the mind, the question is how do you stop it, or would you rather communicate/engage?
In a dream, and I think this is an extension of
a dream, one can try to resolve mental conflicts/concerns by first recognizing they are dreaming, then engaging the dream. Here you know you are awake, check on that - see Lucid Dreaming on the web (I like a book by Stephan DeBerges - think that the name, Stanford U) to see how to determine if you are dreaming or awake.
