Yes. The story in 'Conjuring 2' has its roots in real events. The Enfield Poltergeist case was a well - known paranormal case. The Warrens' investigation of this case, with all its spooky happenings like furniture moving on its own and a girl seemingly possessed, was turned into the movie. This shows how the movie is based on a true life story.
Mostly no. The movie 'Conjuring' is a work of fiction that uses elements and tropes common in horror genres. While it could potentially be influenced by rumors or tales of the supernatural, it's not a direct retelling of a true event.
The true life story involves the Warrens encountering various supernatural events. They documented these cases and their work aimed to help those affected by what they believed to be paranormal forces. In the movie, it showcases their methods of investigation, such as using religious artifacts and their knowledge of the occult to try and combat the evil entities they came across. Their reputation as paranormal investigators made their cases popular, and 'The Conjuring' brought these stories to a wider audience.
Well, it's inspired by real-life cases but the movie adds a lot of fictional elements for entertainment purposes. The basic premise might have roots in reality, but it's not a 100% accurate account.
