Little sister is scared

My little sister was freaked out by an episode of a show she was watching, and for the past two weeks has been sleeping either on the floor of my parents room or with me. What should I do?

By the way, I am a thirteen year old girl and my younger sister is eight

She is experiencing a perfectly normal reaction to an upsetting event. For a temporary period the different sleeping arrangement os OK, but your parents can let her know that, after a couple of days, it's expected that she remain in her own bed.
