What are the key elements of the true story that Anabelle is based on?

The true story that Anabelle is based on has several key elements. First, there was the doll, which was the center of all the strange happenings. Then there were the witnesses, the people who experienced these odd events. They reported things like the doll having a 'presence' that was not normal. There were also the specific incidents, such as the doll seeming to change expressions or positions in a way that couldn't be easily explained. These elements together created the basis for the Anabelle story that we know today.

The key element is the doll itself. It was an ordinary - looking doll that started acting strangely. Another element is the feeling of unease it created. People who were near the doll felt a sense of fear or something not being right. Also, the unexplained movements of the doll, like it moving from one place to another without any human intervention, are important aspects of the true story.

Well, one of the key elements of the true story is the location where the doll was. It was in a particular home or environment where these strange events took place. The people involved, like the family or the nurse who had the doll, are also key elements. Their reactions and experiences added to the story. And of course, the doll's behavior - the way it seemed to have a life of its own, with movements and a sense of something 'otherworldly' about it. All of these combined to form the true story that inspired the Anabelle concept.
