What good vampire and scary supernatural books can you recommend?

I’ve read, Bram Stoker’s Dracula, Elizabeth Kostova’s The Historian and even a book about Sherlock Holmes’ encounter with Dracula ( yes a bit desperate I know ) and still in search of a good vampire tale that is brilliantly written and certifiably creepy.

I am as well looking for extremely disturbing supernatural stories, malevolent ghosts especially which could keep me awake at night turning pages after pages. So thanks if you have anything to recommend. : )
