You are sitting on your bed in your room alone at home, and it is now one in the morning and the entire house is dark. While you are sitting on your bed and talking to your dear friend Tom in a video call, your phone falls on the floor next to the bed, then you get off your bed to grab your phone, then you return quietly. To lie on your bed and then look at your phone and see your friend's face is strange, Then he sends you a message immediately "There's a terrifying girl under your bed."
