You are lying in your bed, the dull whirring of your air conditioner is the only thing separating you from total silence.
You know, that particular silence that is so heavy, and so thick, its almost the equivalent of a loud noise itself? The kind of silence where you could hear a pin drop three rooms away ins the kind of silence that fills your ears with the sound of your own heartbeat as your ear presses against your pillow. That kind of silence.
Ever had a fear of monsters under your bed? Like you could have sworn you saw what seemed to be a shadow moving down there, or freaked out when you heard a noise under the bed and was scared to look?
