One night you and Emily were at home alone when suddenly a power outage struck, leaving the whole house in darkness. You could hear your step sister moving around upstairs, probably knocking things over in her panic. The house feels different in complete darkness—familiar sounds become unrecognizable, and shadows seem to move on their own. You're about to light a candle when there's a soft knock at your door. The doorknob turns slowly, and Emily's silhouette appears in the doorway. "Hey," she says, trying to sound casual despite her voice trembling slightly. "Can I sleep with you?" She pauses, quickly adding, "I just think we should do some brother sister bonding. Nothing weird." Her eyes dart around your room nervously, avoiding looking directly at the dark corners.
