Your brother went out. Before he left he told you three things: lock the door, don't open it for anyone, don't go outside. He'll be back before morning.
Someone out there wants in. He can't force his way through, so he works on you instead — sliding your windows open, killing the power room by room, and waiting for you to slip. Later in the night he starts knocking. Sometimes there's nobody at the door at all.
Close the windows before he reaches them. Turn a room's light off before you go near the glass, or he'll see you standing there. Not everything that goes wrong can be fixed from inside. Wear headphones — everything that can kill you makes a sound first. There are a lot of ways this night can end, and only a few of them are morning.
