Answer:
Jonathan Harker is the real estate lawyer who had come from London to finalize the deal with Count Dracula. He was travelling as the Count couldn't come to London to close the deal.
The castle has an eerie sensation to it, full of dark spaces, surrounded by forests and trees, even the building itself was dark with heavy curtains.
While he was shaving, the Count suddenly appeared, startling him so much he cut himself. Seeing the blood trickle, the Count began to behave like a monster and grabbed him in his throat. He also has no reflection in the mirror, which seemed odd to Jonathan.
Step-by-step explanation:
Jonathan Harker is a young lawyer from London who had come to Count Dracula's place in Transylvania to finish a real estate transaction with the Count. He was travelling as the Count couldn't possibly come to London so he had to go in person to get the deal done.
Some of the Gothic features used in this plot are the dark themes, the setting of the nights, the damsel in distress, the suspenseful mystery plot, the eerie scenes etc. They all provide a feeling of a thriller and suspense. Most of these features are seen in the palace itself, located in a forest, dark atmosphere and even the house was damp and depressing. Thick curtains filled the windows, and the occasional "howling of wolves" which can be heard from the castle.
The two things that happen when the Count interrupts Jonathan's shaving were-
1. The Count have no reflection in the mirror,
2. The sudden appearance of the Count made him so startled that he cut himself. Jonathan admitted in his journal that the Count's "eyes blazed with a sort of demoniac fury, and he suddenly made a grab at my throat".
