The scratching at the door was a constant echo in the back of her mind. Was she still dreaming, or was she awake and there was something at the door to bedroom?
She opened her eyes and the scratching noise continued. It was annoying her now. She got out of bed and went to the door where the sound was coming from, and opened it.
There was nothing there. The noise stopped, and she closed the door and went back to bed.
She closed her eyes and the scratching started again.
This time it was in the bed with her.
