At 9 pm, you are still doing your homework and leave your bedroom window open to make it easier for the wind to come in and make you feel fresh.

Time goes by until midnight. When your homework is almost finished, you hear the sound of something falling from your window, you look that way but don't find anything.

Then suddenly you feel horror behind you and a cloth covers your mouth tightly and a whispering sound comes to your ears.

"Shh, shut your mouth or you'll know the consequences."
