An angel glows in the shadow of our dream world, the place of our mystery, uncertainty and secrecy.
When I am conscious I feel (at least partially) aware of the external world, and to a degree of my inner private world. When I am not conscious I do not feel the rich play between thought, sense and action - although when unconscious the external world may continue to affect me as much as my inner world. Both states may be present when I am awake, and the strength of consciousness ebbs and flows when I am asleep.
It is good to know and to be aware, and yet it is also sometimes good for me to forget, or not to be aware. I enjoy the idea of this duality and feel richer for the interplay of known and unknown. I count myself as fortunate in neither being fully conscious, or unconscious, as perhaps it is here we dream.
