- Dracula: Bram Stoker read Carmilla and its influence, among other things, is evident in the characterization of vampires who attack Jonathan Harker early in the novel. In the oldest manuscript of Dracula, of 8 March 1890, the castle is located in Styria, after the location was changed to Transylvania six days later. The story of Bram Stoker's "Dracula's Guest", known as the first chapter suppressed Dracula, shows a more obvious influence and intact for "Carmilla": Both stories are told in the first person. Dracula expands the idea of a first person narration of a number of different personal cards, to create a story plausible background. Stoker also recreates the air of mystery of Le Fanu work, allowing the characters to solve the Vampire puzzle along with the reader. Descriptions of Lucy in Dracula are similar to Carmilla, and they became vampires misleading archetypes that attract his victims, being described with rosy cheeks, slender, languid, and with large eyes, full lips and soft voices. Both women are also sleepwalk. The influence of Carmilla can also be seen in the character names: "Karnstein" became "Carfax", "Reinfeldt" became "Renfield". Dr. Abraham Van Helsing in Stoker, is a direct parallel with the vampire hunter of Le Fanu, General Spielsdorf: both characters are used to investigate and catalyze the vampire actions.
