If ever you should walk into a dark room inside your empty house and see a shadowy figure somewhere within, don’t turn on the lights. It’s better not to know. Don’t run to the bathroom, lock the door, and cower in your bathtub. Don’t hurry to a closet, lock the door, and hide underneath a pile of clothes. And especially don’t return to your bedroom, lock the door, and crawl into your bed. Because every other door in your house was already locked, and the figure still managed to get in.
