At night, you are sleeping on your bed, with your white blanket and 2 pillows on your head. You turn off your room because you prefer your bedroom lights to be turned off at bedtime.

Then, suddenly your bedroom window opened wide, the moonlight that night entered your dark room. And you can see black dust swirling around the middle of your window. A tall man appeared, on his head there were 2 horns.

"... Hello there..." He smiled at you.
