Dracula 7

"There was in the room the same thin white mist that I had before noticed... I felt the same vague terror which had come to me before and the same sense of some presence. I turned to wake Jonathan, but found that he slept so soundly that it seemed as if it was he who had taken the sleeping draught, and not I. I tried, but I could not wake him. This caused me a great fear, and I looked around terrified. Then indeed, my heart sank within me: beside the bed, as if he had stepped out of the mist—or rather as if the mist had turned into his figure, for it had entirely disappeared—stood a tall, thin man, all in black. I knew him at once from the description of the others. The waxen face; the high aquiline nose, on which the light fell in a thin white line; the parted red lips, with the sharp white teeth showing between; and the red eyes that I had seemed to see in the sunset on the windows of St. Mary's Church at Whitby. I knew, too, the red scar on his forehead where Jonathan had struck him. For an instant my heart stood still, and I would have screamed out, only that I was paralysed."
Chapter XXI, Page 305

This passage depicts when and how Dracula first appears to Mina when she is awake. It contains several examples of symbolism, most prevalent being the physical appearance of the Count. The clothing he wears is black, symbolizing his intentions as well as his relation to the darkness and by extension. The scar on his forehead seems to symbolize that, however, he can be damaged. The way he appears from the mist is reminiscent of the sexual connotations of his feeding by the way he enters the room as the mist, sneakily, seductively. Also, the fear that Mina feels and the darkness of his appearance is a Gothic trait.
