In The Dead Of Night
That night, around half past two in the morning, Tracy was awakened by creaks coming from the ceiling. But this time, she also heard gentle beating noises on the floor of her own room.
She looked down and in the twilight of the night, she saw a number of nails scattered on the carpet. She realized that the nails were coming out of the planks of the ceiling. Her heart stopped – it was not a possum or a raccoon.
