Exposition: Jackie and Don Gale buy a new house in the woods. Don wanted a change of scenery from their usual city life. Don has to leave for a business trip leaving Jackie with the dog, and whatever lurks in the woods.
Rising Action: Things start to get strange and Samson, the dog, is also acting weird. Samson is not acting like himself, and things are starting to "go after" Jackie. Books are falling on or near her, and things falling in general.
Climax: Jackie lets Samson out, and he takes off. Jackie is frantic and she doesn't know what to do. So she grabs a flashlight and goes outside to look for Samson. (This night she was hearing/seeing things outside)
Falling Action: Jackie goes out in the dark looking for the dog, but she can't find him. She hears scary noises and bushes rustling telling herself "it's nothing". (Supposed to feel like the end of the story is soon, and the BOOM!)
BIG Event: Finds dog being eaten alive by demon. Demon runs, and the dog tries to crawl to her but whimpers and dies. Jackie starts to cry because her dog is dead and she is scared. She sees the demon and it starts to run towards her.
Resolution: She wakes up it was an all true real nightmare...
