Here's why:
* Supernatural Elements: The story heavily features vampires, a classic element of the Gothic genre.
* Dark and Atmospheric Setting: The novel takes place in gloomy castles, remote locations, and often at night, creating a sense of unease and mystery.
* Psychological Themes: Dracula explores themes of fear, obsession, and the struggle between good and evil, which are common in Gothic literature.
* Emphasis on the Supernatural: While it has elements of the supernatural, it doesn't delve as deeply into psychological horror as, for example, Edgar Allan Poe's works.
It's also worth noting that "Dracula" has elements of other genres, such as:
* Romance: The love story between Mina and Jonathan Harker adds a romantic element to the plot.
* Adventure: The characters embark on a dangerous quest to defeat Dracula, featuring elements of suspense and action.
However, the core themes and atmosphere of the novel firmly place it within the Gothic horror genre.
