Although being atheist does make me a skeptic first and foremost, I have followed the stories from Lorraine Warren on the hauntings she's encountered.
The creepy thing is how she and her husband Ed kept from many cases objects that are meant to contain supernatural presences, including the infamous annabelle doll, and she has a priest come by and bless the place she keeps all the objects.
This is one of these things where I fall into the catagory of more agnostic, in that I don't know what truth there is to all this, but maybe there might be something.
The conjuring was a good movie at least.
