I used to have a recurring nightmare as a kid. I'd be in the living room with my family and I'd hear noises that no one else hear from outside and then I'd hear faint laughing and I'd see an odd shadow moving about outside, the laughing would get louder and i'd start hearing an awful scraping sound. Eventually this monstrous man with long claws would appear at the window and he'd laugh and smile at me and drag those claws across the window pane to try to get in. He'd then disappear only to rip his way through a wall and come to get me while my family did nothing.
Looking back this nightmare man was very much like a Freddy Krueger figure but I never actually watched those films until I was a teenager
