While the ghost has reportedly been seen many times before, this is the first time the phenomenon has been captured on film.
"When we arrive at a new venue, we explore first before we turn the cameras on, just to get a feel for the place and see whether Derek is receiving any psychic connections. It felt really eerie and intense and Derek could tell very quickly that someone was nearby, moving around the rooms with us," Palmer added. "We then began to record the introduction to the episode, but were drowned out by tapping, banging and footsteps. They came from out of nowhere and we knew we were the only people in the castle at the time. It was just us and our two crew members in the room. We tried to find the source of the noise, but it quickly went deathly quiet. We normally like to try and debunk things that we see because we still sit on the fence when it comes to ghosts, but we don't think there's any other explanation for what we saw."
