Ghost caught on camera at Warwick Castle

Ghost caught on camera at Warwick Castle is a commercial satirizing this parody of Ghost in the London Dungeon.

It starts off with a text reading: "This video is 100% real and was captured by security cameras at Warwick Castle. The ghost was caught on camera while builders were working on the new Dungeon attraction. Watch the bottom left quarter of the screen where the two builders are talking. If you put on your speakers and listen carefully you can hear strange, inexplicable background noise."

In the next scene, there are 4 security camera images, The time-stamp 01:20:00 is displayed early on when happen, the image goes fuzzy at a moment changes, and the time-stamp advances to 01:49:10, a ghostly figure moving slowly and two guys walking the hallway. however, after 53 seconds, a ghostly man pops up accompanied by a high-pitched scream.
