@metrouk: Have you ever wondered just how scary London's Halloween attractions actually are? 🎃👻 We sent @phoebewilliams to put three scare experiences to the test, tracking her heart rate as it hit a terrifying 159BPM at one point. From jump scares to creepy characters, @The Nightmare Realm @Horror Escape UK and @The London Dungeon all gave her a fright, but one was officially crowned the scariest 👀 Which one would you brave? #Halloween #Scary #Attraction #London #Horror
