What are the words Charlotte used to make the story seem scary?

There are eerie and intimidating passages throughout Jane Eyre. One section that could be deemed scary is the opening of chapter 28. This chapter occurs right after Jane's attempted wedding with Mr. Rochester. When at the alter, Jane found out that a legal marriage could not happen between them, because Mr. Rochester was already married. His wife, Bertha Mason, went insane. Nonetheless, it was practically impossible for Rochester to get a legal divorce from his wife at this time. He was stuck with her until her death. She lived, with a personal servant, upstairs in Rochester's mansion.
Rochester tries to apologize to Jane, explaining why he didn't feel his marriage to Bertha counted as a real marriage anymore. He even tries to convince her to run away with him to some place where they could live as though they were husband and wife. Jane, however, is unhappy with living out only the appearance of marriage. She does not want to be Mr. Rochester's mistress—she wants to be his wife.
Though she claims she forgives him, Jane makes the decision to leave Rochester's mansion. Since she cannot be his wife, she does not think it is proper that she continue living in the same house. Chapter 28 picks up two days later. Jane has been traveling in search of some other place to live in work. (This is particularly challenging for a single, unmarried woman in the 19th century.) Jane explains her situation:

The coach is a mile off by this time; I am alone. At this moment I discover that I forgot to take my parcel out of the pocket of the coach, where I had placed it for safety; there it remains, there it must remain; and now, I am absolutely destitute. . . .

Jane's solitude is scary in this passage. She has no one to help her and no money or personal items, since she left her bag behind on the horse and carriage. Next, she explains her environment:

There are great moors behind and on each hand of me; . . . The population here must be thin, and I see no passengers on these roads: they stretch out . . . white, broad, lonely; they are all cut in the moor, and the heather grows deep and wild to their very verge. . . . I struck straight into the heath; I held on to a hollow I saw deeply furrowing the brown moorside; I waded knee-deep in its dark growth; I turned with its turnings, and finding a moss-blackened granite crag in a hidden angle, I sat down under it. (chapter 28).

In this passage, Jane is wandering in a moor, which is known for having only low-growing vegetation. In other words, the lands are vast and open, without any large trees. This adds to the sense of Jane's loneliness. Words such as "wild," "moss-blackened," "lonely," and "dark growth" show the eeriness of this setting. In this huge, open area, Jane finds a piece of granite that she can take shelter from the weather under. However, she is still unhappy, unsure of what to do, and uncomfortable:

I had a vague dread that wild cattle might be near, or that some sportsman or poacher might discover me. If a gust of wind swept the waste, I looked up, fearing it was the rush of a bull; . . . Finding my apprehensions unfounded, however, and calmed by the deep silence that reigned as evening declined at nightfall . . . . I had only listened, watched, dreaded . . . What was I to do? Where to go? Oh, intolerable questions, when I could do nothing and go nowhere!(chapter 28)

Jane continues to be uncomfortable, despite the fact that she has found a spot of shelter from the wind. (Since there were no trees, not much blocked the wind. It would have been very cold and uncomfortable for Jane in this environment, especially since she has no extra clothing with her, since she left her bag on the coach.) Words such as "vague dread," "fearing," "deep silence," "nightfall," "dreaded," and "intolerable," "nothing," and "nowhere," show the fear that Jane had in this situation. Jane's situation is extremely bleak at this moment. Many of these words make Jane's situation seem scary.
