All Alone

This is from the point of view of a possessed doll. Her name is Sarah. She was a regular human but she came into the house as a dare and got possessed. She's trapped there for 666 years and she can only get out is somebody has an emotional attachment to her. That person switches places with her. She is trapped for 76 years, undisturbed, in a dusty cellar until 3 ghost hunters come into the house, looking to earn money. What they find is something much different.
