Ok - I did an investigation for a family who lost a family member. It's important for you to know that when I do go on location, I do not what to know anything about the location!! I was told nothing not even why I was there and that's how I like it.
Claps to the floor, holding my throat and what might have felt like to some as an attack, was not. She lady was a famous ventriloquist, who died of throat cancer, she had a dummy she named Skeeter - The sister stole the dummy and sold it, as it was worth a lot of money, because of who she was and the gift she had.
In the end the family was looking for the dummy and oddly enough the writing was on the wall.
I have tried to place two pic one at the normal shot as I took it and the other a close up. Maybe you too can see the writing on the back wall. Yes, please do not worry about the shadow beings, there in most pics I take. There is also a wolf, but that was her pet - I am focused on the writing on the wall as the dead talk and write (not well, but who am I to judge)

Photo 2 close up (I do not like two as it is to blurred)
