Horror themes often explore the darker aspects of human nature and the unknown. Common elements include fear of death, the supernatural, and psychological terror. These themes can manifest through monsters, ghosts, or even the human mind, creating a sense of dread and suspense. Another prevalent theme is isolation, where characters find themselves cut off from help or society, heightening their vulnerability. This can lead to paranoia and a struggle for survival. Classic examples include Frankenstein and Dracula, which delve into the consequences of unchecked ambition and the fear of the other.
