Parents guide

A girl is wearing a fairly low-cut blouse and convinces her roommate to wear a similar one. Her boyfriend reaches under her blouse, as though he's trying to take it off or trying to touch her. Sam and Dean go to a sorority party. Several girls are wearing revealing clothing.

A man is hanging on a rope by his feet from a bridge. He has a cut across his chest and there is a good deal of blood. A girl is found dead in her bed. Her blood is pooled on the ground and all over her sheets. There is a message scratched with blood into the wall above her bed. A man appears behind another man and stabs him with a hook.

A man scratches some signs with his hook-hand, then vanishes. He scratches the side of a car while invisible. Later, the person who was driving the car is hanging on a rope upside down by his feet from a bridge overhead, dead. A man appears behind a door during the night. Dean digs up a skeleton and burns it. Dean and Sam fight a ghost/monster. When they defeat it, it dissipates like a sheet of paper being burned.
