Just a couple of weeks ago, this was the view at 10 pm at night. Before we arrived in Alaska we thought about how to sleep through days with 20 hours of daylight. We have room-darkening shades on the coach windows but the bathroom has a skylight. At night we could close the bedroom door, but the cats interpret that as a violation of their rights and paw at the door endlessly, regardless of which side they are on. The door is just loose enough to rattle a bit when they push against it, and that get real annoying, real fast. So we bought one black, lined window drape and strung it on a rod over the door. It's long enough to cover the doorway completely and block the light from the skylight. We haven’t missed any sleep!
