Kay bolted upright in bed.
She could swear she heard something. A crack, a thump; something low and bassy, but sudden, and loud, and it came from beyond the closed door to her bedroom. She moved her phone aside to see the bright red numbers on her nightstand radio: 3:03 AM.
She sat very still in the pitch darkness, her concentration entirely focused on what she could hear — which at the moment was nothing.
A minute crept by. She slept with every door in the house shut; something she used to do when she was younger because she was afraid of ghosts. She realized it was stupid to assume a ghost would bother to open a door, but it made her feel safer. Just as pulling the blankets over her head did, which she contemplated doing.
