As the chiefs mind clears, he becomes aware of his surroundings. Describe the scene which captures his attention as he looks out the window

In Chapter Seventeen, Bromden wakes one night to find the ward clean and silent. He gets up and walks over to the window. He looks outside, and for the first time, he seems to really see the outside world. He can see that the hospital is surrounded by countryside. He watches a dog sniffing around outside until Geever, one of the boys, and the Catholic nurse put Chief Bromden back in bed. Bromden dreams about how the nurse goes home and tries to scrub away her birthmarks, aghast that a good Catholic girl has such stains.
