(Deleted video)

Lost

[Deleted video] is a screamer video uploaded by a YouTube channel with no name, but whose creator goes by the name "Angel" elsewhere.

The video's thumbnail is YouTube's old default thumbnail for private/deleted videos, tricking the viewer into thinking the video is already deleted but can be still accessed by clicking on it. However, when the video is clicked on, Regan MacNeil from The Exorcist appears with the same scream from The Maze. Over 100,000 viewers have been tricked so far with this technique.
