This one is just bloody terrifying full stop. Monsters hiding in closets or under the bed are a thing of nightmares for most kids. A skeletal type monster with crazy hair would definitely terrify me as child.
The Nightmares Fear Factory in Canada claims to be the scariest haunted house attraction in the world. And after seeing these pictures... they might be right. There is a hidden camera that snaps photos right at the scariest moment of the tour. I have no idea what happens at this moment, but judging by these people's reactions... it's absolutely terrifying!!
