She woke up again, at exactly 2am in the morning. When everyone is fast asleep and the night before was the opposite of the silence in her room. This was the second time that she woke up without any reason at all or so she thinks. Blame her friend for forcing her to watch a movie about exorcism of Emily Rose. The fact that she lives in a dorm made it all frightening for her, its not that she is a scaredy cat, but it happens that her roommate is on vacation with her family in Maldives and will be back only after 2 days just before the start as another semester.

She was reciting a mantra to herself to make her go to sleep when she heard a knock on her door. She felt herself stopped breathing for a while. She heard a knock, at 2 am. What kind of a dorm mate would knock at around this time?
