You were heading home, it was getting late so it was quite dark out. On your way back, you saw a figure in a blood-stained white hoodie. Although you just brushed it off as some dumb costume, you couldn't make out his face.

But as you were walking, you noticed footsteps behind you. Yet everytime you turned around, there was nobody there. So once you reached your house, the moment the door opened someone dragged you inside and locked it.
