The creation of the horror image and the gloomy atmosphere in the novel is realized by spreading the devil world centered on Dracula, making the readers like a horror drama staged in the dark and dirty old castle. At the beginning, the novel presents a series of mysterious and dramatic images, such as a remote old castle, a desolate night, a sudden werewolf, and a strange bat.
The unknown smoke and other images serve as background factors to arouse readers’ memories and impressions of the grim and horrible scenes, so as to present a terrifying world to readers. This technique was also widely used in 19th century Gothic novels. On the one hand, it introduces the characteristics and identity of Dracula, on the other hand, it also employs these images to expand readers’ imagination and enhance their understanding, which sets a tone of terror and panic for the whole novel.
The existence of Dracula and the perception of his image are the self-perception of human eyes or psychology and the vivid description and presentation of the current social mentality. Jonathan’s visit and familiarity with the castle actually started the contest and struggle between good and evil, and at the same time hinted at the subtle relationship of conquest and resistance between the British Empire and the colonized countries at the end of the 19th century. The novel presents the reader with a strange and deviant world. In such a world, the reader is as anxious as the monster is terrifying. Dracula represents a strong possessiveness and a desire for racial invasion. He tried to invade London from far away eastern Europe, and while women were sleeping, he controlled their consciousness and drank their blood to reproduce his own race, expand his territory, and dominate the British Empire.
At the same time, the women who had been sucked into the blood were transformed into social outliers. They broke away from the male authority and were no longer bound by traditional concepts and customs, and freely expressed their likes, dislikes and desires. They possessed the characteristics of the new females emerging in the British society at the end of the 19th century, which was not recognized by the mainstream population at that time. The image of Dracula’s attempt to overturn the harmonious and orthodox order of British society was the accumulation of capital in the British Empire. The shadow of colonial expansion and self-portrait are the reverse of imperial colonial rule. At the same time, Dracula’s whole scheme is a symptom of the waning British empire’s fear of its own political future, a looming fear of the vassal states that are rebelling against colonialism and the rising powers that are gaining momentum.
