The Strange Case of Dr. Jekyll and Mr. Hyde takes the idea of transforming into something inhuman and turns it on its head. In Dracula, we see a few different characters become taken by vampirism, in varying ways. Lucy is obviously the most dramatic example of that, turning into a permanent vampire (until she is killed/exorcised with the help of Van Helsing). All of these transformations in Dracula, however, are involuntary, in that they are the direct result of having been bitten (or visited) by Dracula. Meanwhile, in the case of Dr. Jekyll, his transformation is a result of his own experimentation, and after the discovery he chooses to transform into Mr. Hyde whenever he wants to. Although, similarly to Lucy, Dr. Jekyll eventually loses control over his other form, at which point it takes him over completely.
The emphasis on self-indulgence in this novella reminded me of similar themes running through Dracula. We know that Dr. Jekyll transforms into Mr. Hyde specifically for his own pleasure: “The pleasures which I made haste to seek in my disguise were, as I have said, undignified…every act and thought centred on self; drinking pleasure with bestial avidity” (Stevenson 46). I found it interesting how Dr. Jekyll indulges his desires without much thought, while the human characters in Dracula are shown to resist them, such as when Harker is deeply tempted by the three female vampires but does not give in. Also, in Dracula, we see the idea of indulgence with the consumption of blood, and in other words, violence against other people, just like Mr. Hyde attacking that girl or killing the old man.
