2. The Conjuring (2013)
The Conjuring follows the story of a haunted house and two paranormal investigators, Ed and Lorraine Warren who are hired to help the family get rid of the evil spirit. It turns out that the evil spirit is the witch called Bathsheba who lived on the property and sacrificed her baby to the devil and cursed everyone who wanted to take her land.
Well, witches and evil spirits don’t exist, so how scary can it be? Well, actually, the movie was based entirely on the true story and Ed and Lorraine Warren were two actual paranormal investigators (Lorraine is still alive) who were summed by people who had problems with evil spirits.
