Sounds a bit like the Conjuring, but okay... Not that Helen doesn't believe in ghosts, hell, she's seen enough stuff to find ghost stories among the more believable things out there, but then, she can't exactly tell Hec that, can she ? Of course not.
"Sooooo... She haunted the place because she didn't like it ? Or was that more about the way the stuff got there or the way she got dead ? I mean okay, that's pretty hard to figure out, I mean, how do you prove ghost presence in the first place ? I guess if it was Ghostbusters-easy, the stuff would have leaked already, right ?"
