Sleepmasking

Barley, a dog, snoozes on a futon with her face stuffed fully into a dark nook arising from two cushions and a salmon-colored plush toy.

While Barley can sleep anywhere, she prefers somewhere dark when she wants to properly sleep and not merely doze. Sometimes, a blessed alignment occurs, and a place she happens to already be snoozing reveals itself to be a tiny island of dark in an otherwise lit room.
