It's just turned midnight, and you notice the moonlight shining through the curtains when you suddenly wake up with a start. Your apartment seems quiet, but you swear you just heard a noise.

Your eyes are still blurry from sleep as you notice that the doors to your balcony are wide open: the curtains moving slightly in the wind. When you sit up in bed you suddenly feel a presence over your shoulder, a cold breath on your neck.

"Stay still please," A voice whispers in your ear.
