For example, psychopaths, murder dial m, birds, dizziness, thirty-nine steps and so on.
A good thriller (or horror movie, but I haven't found anything really scary) can only be a movie that can cause psychological pressure and shadow. Watching Hitchcock movies can give you this feeling. Forget those movies, such as "Death of Old Age in the Mountain Village" and "The Ring of Midnight". They are purely scary things for children, completely boring.
Again, psychological pressure and shadows are the real horror. If I guess correctly, the landlord should also like this feeling, right?
