Vampires are creatures of folklore and mythology. While there were beliefs in various supernatural beings and creatures, such as fairies, witches, and ghosts, there's no historical evidence to support the existence of vampires.
The Victorian era, while fascinated by the macabre and gothic themes, primarily drew its vampire imagery from literature, not from actual belief. Authors like Bram Stoker, whose novel "Dracula" is considered a seminal work on vampires, created and popularized the modern vampire myth.
Therefore, the idea of vampires in old Britain, especially the Victorian era, is a fictional concept that emerged through literature and popular culture.
