How is the novel 'Dracula' reflective of the universal fears felt at it's time?

Our initial introduction to the novel presents itself as a written account of a journey. Our narrator, Jonathan Harker, informs the reader that he is "leaving the West and entering the East". The late 19th century was characterised by fear of reverse colonialism. This fear often became apparent in the literature of it's time. Harker continues on from this through his assessment that "the further East you go, the more unpunctual the trains" this criticism can be adapted to mirror the West's outlook on the East during this period. It reflected the fears of the archaic and unrefined Eastern Europe. Landscapes such as these were commonly used in Gothic Novel's during this period to present a sense of isolation and to present a physical distance between all that which is rational.Furthermore, the novel finds itself exploring the Victorian mindset of sexuality, or more accurately it's resentment of it. The three Vampire women are described as "voluptuous" and Lucy Westerner is late described the same after her vampiric transformation. Harker finds the women to be "thrilling and repulsive" this oxymoronic description embodies how Victorian Society react toward female sexuality. Women of the period were expected to refrain from promiscuity and yet men sought it out from prostitution, hence the boom in the trade during the late 19th century. Throughout the novel, female sexuality is synonyms with vampirism - a corrupting influence that destroys the innocence of women.
