Something..

Louise is a girl, 19 years old, height 175.
Louise hadn't been sleeping well all week, was incredibly stressed, and toward the end of the week, she began hallucinating. She'd see something in the doorway, or something would fall, and so on. Sitting, talking to a friend on the phone, she saw a box sitting on the closet fall. Looking down, Louise saw a black creature in a sweatshirt and pants with white dots for eyes and a frightening smile, revealing sharp teeth. But the creature instantly disappeared. Louise continued the call, trying not to panic, realizing it was most likely hallucinations. But when she looked at the table, the "something" was there again, but again, it instantly disappeared. Louise tensed and hung up. She rubbed her tired eyes and looked to the side; the "something" was sitting almost in front of her face. Louise nodded slightly and tried to move away, but the creature grabbed her arm, preventing her from escaping.
