Noise in The Night

Two roommates remain at their deserted college dormitory over a holiday break.
One of the girls goes out on a date that evening, and the other one turns inand goes to bed before her roommate returns. Later that night the sleeping girl is awakened by gurgling and scratching noises coming from outside the hallway door.
Frightened, she locks the door and cowers inside the room until morning. When the girl finally opens the door and ventures outside, she discovers the bloody corpse of her roommate in the hallway. The murdered girl's throat had been slit, and she had bled to death in the hallway while clawing at the door.
