This is what happens when you watch Black Swan late at night.

Stop, a voice says. Hairs stand on end. Chills run down the spine. Her eyes ever so slightly glance over her shoulder. A quick double-take confirms: no one is there. A shake of the head and onward she walks. But she can't eschew the feeling that some one is watching. She turns again, scrutinizing her surrounding, but she's unsure she's even seeing what's really there.

"Nothing's there," she mutters to herself. Yes there is, says the voice.

Something quickly catches her eye. A twitch in the dark. She squints, trying to better define the darks shapes, but it's no good...and too late. A woman edges out of the shadows, but keeps her face hidden from view by the hood of her jacket.

"Who is that?" She asks the woman, scared. But the woman didn't answer; just groveled along, getting closer to her. Too close. She steps back. "Who are you?"

The woman raised her head just high enough for her to see the crooked and insinuating smile.

A sense of horror flooded her body as she decided to look down at the woman's hands. Something silver was gleaming... She started running, but didn't get too far. She tripped over the uneven pavement, and fell to her hands and knees. She heard the woman running after her. The girl whirled around and saw the woman standing above her, knife in hand, ready to thrust. The girl let out a piercing scream and tried to fight the woman off; but she was weak. Too weak. In a last attempt, the girl threw the hood off the woman's face. But what didn't make sense to her was that she was looking back at herself. That brief moment of confusion did it though. The woman took her chance and shoved the tip of the knife into her stomach. The girl let out a piercing cry of pain. She closed her eyes, and the woman shoved the knife in deeper.

She waited to hear the woman's departure, but it never came. Was she waiting to watch her die? The girl slowly opened her eyelids, and screamed.

There was no woman. Just her reflection in a window; a reflection of herself thrusting the knife into her own body. Tears streamed down her face as she slowly retracted the knife. Blood everywhere. She laid herself on the ground, confused, terrified, and remorseful. What had she done? She watched the world around her slowly swirl into blackness.
