On the computer Mother and I had open a portal to a dimension where everything is exactly the same but reversed just like looking at the house through a mirror. Everything looks calming and quiet with not a sound to be heard. Yet if a sound was to be heard a child would hunt down whoever had made the sound and point it out for a humanoid being whose eyes and mouth is shut not sewn but as if it could not be opened, they will be gliding across the floor like as if they were floating but still touching the ground. They chase down the person the child points out and takes them away into darkness with no knowledge of how to stop them or what they'll do.
