Is it normal for a child to be obsessed with scary films and stories

Hi omg my son is the same he's just turned six hes been into these things since he was about 3, he saw his older brother watching a movie,but he has a chucky doll too he loves watching movies and even online he watches things on utube he don't get scared as much now he takes chucky to bed he loves pennywise and all that u have mentioned above he seems ok he talks about it with me at first I was worried about it as didn't think it was normal but I love horrors myself I guess it's rubbed off, and Halloween is big for us love it,personally I've sat with him saying these things ain't real that movies are made to scare adults as not much scares us lol he's 6 and now he wants to make scary movies when he's older that's what he said,he still dose normal things like dress up as superheroes and watches kids cartoons and films, He's never done anything like harm animals or his older siblings or myself he's very loving,bit now wants slappy the doll,personally I think he will out grow it but all I can do is make sure what he is watching and make sure that he understands that it's not real and that the baddies are baddies
