I just watched it and tbh I believe that most people experienced heavy foot steps, loud bangs, etc because of the power of suggestion.. you were already paranoid hence the anxiety because you were watching a scarey documentary. And the fact that the seed is planted into your subconscious from the very beginning with the warning that it's cursed and to watch it at your own risk further more proves that most of the experiences are subconscious. Possession is scarey and seeing exorcisms in movies already has the fear burried in the back of our minds. Its psychological and the brain is a very powerful organ. And as far as the expert accounts, it's in the movie that the claims may be fueled by money. And for the right price almost anyone will say what you want them too while you record it.. I mean where are all the claims from people who lived there before the Ammons family? If other people died in the house why is it only them who were possessed? Why is it only them who experienced stuff but yet the squatters living there after they moved didn't? I bet for the right price they'll make any claim... So relax y'all. Well played Zac, well played!
