There are demons to be found there but also little epiphanies as the eyes become heavy and we want to remember all in the morning. The thoughts swirl and dance in our heads until we are carried into what will hopefully be restful slumber.
Our fears and aspirations flash before us in those moments as well as the far off memories of things that passed and could have gone differently. We don't know where that door taken might have led. Those moments between the sobriety of reality and the dreams that may come are the way we unload the little crosses we carry and set them down just for a while until the morning returns once again.
