It started a little over a month ago.
I was at my Aunt's house, visiting. We live in the same town, so I visit weekly after school.
At first, when I saw the shadow, I thought it was a shadow of a passing car- its a rather busy street at that time of day. Then my mom asked if I saw it. I said yes- and that if it wasn't the shadow of a passing car, perhaps it was Grandmother or Grandfather checking in on us. They had both died in the house. Nothing more was said and the matter was let to drop- the thought wasn't that odd (ghosts are oddly common in my area).
A week or two passed.
I saw a shadow pass over a light and down the wall, and ignored it- thinking it was my imagination- and went to take a shower. In the shower, my feet firmly in place and for the first time in years, I fell. Nothing odd about that,right?
Not so much when only one side struck the tub and I ended up not only bruised on both sides, but the one that struck the tub's- my shoulder, had three scratches on it. Then if that wasn't odd enough, when I pulled myself out and stepped onto the bath rug, I fell again as if I had been pushed.
A week later,I'm woken up by my leg being pulled out of socket.
I'm seriously considering getting one of priests from the local church to come out and bless the property. In fact, if it happens again I'm doing so regardless of what any one has to say about it.
I've said as much, and so far, all activity in the house has stopped. I've been having trouble with things outside the house for two years (every time I see one apparition the dogs end up acting as if they had a seizure, or were poisoned) but that's a story for another time.
And I also agree with your decision to have a priest over if these things continue. There may be no paranormal causes, but better safe than sorry!
