Here are some examples:
* "The Fall of the House of Usher" (1839): While Roderick Usher isn't a traditional vampire, his decaying physical and mental state, along with his incestuous relationship with his sister Madeline, can be seen as reflecting themes of vampirism. Madeline's eventual return from the dead and apparent consumption of her brother's life force can be interpreted as a vampire-like act.
* "Ligeia" (1838): The story revolves around a man who marries a woman named Ligeia, who possesses an intense, almost hypnotic, personality. After her death, he remarries, but Ligeia's spirit seems to haunt his new wife, ultimately claiming her life. While not a literal vampire, the story explores themes of obsession, possession, and the persistence of the dead, similar to traditional vampire stories.
* "Morella" (1835): This story features a woman named Morella whose daughter is born with a striking resemblance to her. As the daughter grows, Morella seems to fade away, and the daughter eventually claims to be her mother's reincarnation. While not a typical vampire story, the themes of doppelgangers and the persistence of the dead can be interpreted as having vampire-like aspects.
Poe's stories often explore the dark side of human nature and the ambiguity between life and death. While he didn't write about vampires in the modern sense, his exploration of themes like decay, obsession, and the supernatural resonate with the themes that often surround vampire mythology.
