Behind the curtain
She opened up the bathroom door slowly and walked inside, the light bulb inside the bathroom was burnt out so it was the only room that was still dark. She walked in and turned on the light on her cell phone. Whatever was making noise was inside her somewhere and she was going to find it.
Then, from behind the curtain of the shower, she saw the shadow of something move around. She knew that it must be the cat, but for some reason, something here was just not right. The entire atmosphere was so heavy and creepy, that she was afraid to pull back the curtain, but she did anyway.
