Turn off all the lights. If it’s still light, go into a room, like a bathroom, that doesn’t have much in the way of natural light. Turn on only a flashlight. Stare at the shadows on the walls for a few minutes.
As you sit alone, think about the shadows and the darkness.
What are the different shapes? What kind of creatures are hiding in the shadows? What are the shadows hiding?
What else do you notice? Are you creeped out? Are you comforted? Do you feel reassured?
What did the silence say to you? Or did you hear noises? Maybe an echo you couldn’t hear of someone talking in another part of the house, or the thunder of the washing machine.
