I'm interested in the dream and subconscious mind, the peculiar dream-like quality of our lives, sometime nightmare quality of our lives.

Acting is just a process of relaxation, actually. Knowing the text so well and trusting that the instinct and the subconscious mind, whatever you want to call it, is going to take over.

What can one do with levels of gloom and guilt, fear and disbelief, of bewilderment above one's capacity to register?

You affect your subconscious mind by verbal repetition.
