dreacula pg 46

"It had been so forcibly driven against the jamb that part of the woodwork was splintered. I could see that the bolt of the lock had not been shot, but the door is fastened from the inside. I fear it was no dream, and must act on this surmise." pg 46

The author uses imagery to convey that dark mood. Using diction like forcibly driven helps to create the image of rough harsh movements to lock the door. He wants him to stay in there, or to keep others out. Using this diction helps to create that tone of fear that the narrator is feeling. By reading this you can understand the terror that he is feeling; being trapped and no way out. The syntax also helps to convey this because it is long run on sentences. This helps for the reader to understand that he is thinking nonstop in his head. He just keeps on thinking of more things to add into the sentence. When this happens it gives that sense of fear that the narrator is experiencing.
