It starts with an old guy telling 3 stories, i dont remember the stories but here are some parts: a girl ran over a man in the snow but decides not to help him, the dead guy follows her home and appears bloody in her garage then continues to follow her around while she tries to kill him. the 2nd story is a group of friends go swimming in a lake where it says no swimming, then something tries to kill them, it's like a really huge leach or deformed water or something.. they desperately try to escape as they get killed one by one, the last guy escapes by swimming away from the monster but he gets killed by it upon reaching shore. the 3rd story i dont remember. It ends with the old man again. this was 6 or 7 years ago.

Thank you!!
