Late at night, when you are lying on the bed preparing to fall asleep, the old book beside your pillow is quietly opened, and the mysterious little story follows you. There is a girl with a strange face who appears in the mirror while combing her hair at midnight, a mysterious visitor who always knocks on the door at three in the morning, and a "friend" hidden deep in the closet who imitates your breathing... Each story is short and concise, but can make you feel a chill in the dark. They are whispers before going to bed and the prelude to dreams, taking you into one strange world after another that is both familiar and strange.
