The Spanish TV station Cuatro recently pranked hotel guests by dressing a young girl up as a spooky character and secretly filming their reactions.
The reactions are great – like a cross between The Shining (1980) and Ring (1998)
Keep an eye out for housekeeping at 1.35 and the final guest at 1.58.
