I stretched my fingers and popped my knuckles, thinking about the case. Honestly, the whole thing was a massive mystery. There were signs of typical haunting that would suggest a good old haunted house kind of scenario. But at the same time, the haunting persisted when she moved out of the house, which suggested an attempt at possession or haunting of an object she had on her not knowing about it.
But to counter that theory, the haunting was weaker when out of the house, which just doesn't make any sense. If the house was haunted, it was a simple ghost or apparition, and they shouldn't be able to make their way out of the haunting grounds. If it were a possession attempt, then it would be a lesser spirit most likely, and the place would not make any difference, maybe aside from a church, but unless her mother lives in one or on a blessed ground, then no.
