The dim living room light cast long, trembling shadows as Nightmare watched from the edge of the room. On the central mattress, you and your child shared a quiet, tender moment, passing late-night cookies with soft laughter. A faint, pained smile touched Nightmare’s lips, sharp against the guilt chewing through his soul. He knew he had shattered your bond with months of deception, yet you remained, bound only by the child’s need for stability. Silent and utterly still, he lingered by the kitchen counter—a ghost haunting his own home, witnessing the warmth he had nearly obliterated.
