This clip could be a scene out of a scary movie. Imagine you wake up in the middle of the night and your 16-year-old sister is standing next to your bed staring at you like a zombie. You keep shouting and calling her name, but she doesn't flinch.
And even though you know she's sleepwalking . . . it's still creeping you out because it's going on for almost a minute. It finally ends when the mom comes into the room and wakes the sister up.
