My video disappeared

While on a haunted tour at the revolutionary war museum, Fort Williman Henry, In lake George NY. I was shooting Still photos and videos to see if I could catch any paranormal activity. Nothing happened until we got downstairs to the surgery display. There was a blank brick wall to the left of the surgery, I started videoing at that brick wall and was going to move left to the display. As I was taping the wall, my phone camera began to go in & out of focus. I stopped it and started it twice with the same results. There was no logical explanation nor were there any visible obstructions.
That stopped when I to the display.
When the tour was over, I went to show the director of the tour the video of the wall, it was gone. everything else was there, not the surgery wall. While discussing this with the director she told me her phone shuts off by itself when she goes downstairs to the surgery.
I concentrated on this & went into my caulbearer zone. I heard A voice tell me that occurred because the surgery that was taking place, was too difficult to watch & it was private. THERE WAS NOTHING THERE!
Lately, I have been getting many paranormal events where I am being told it's revolutionary soldiers. I believe the souls from the American Revolution are upset and something is coming... We will see soon enough.
