Probably, if I had lately left a good home and kind parents, this would have been the hour when I should most keenly have regretted the separation: that wind would then have saddened my heart; this obscure chaos would have disturbed my peace: as it was I derived from both a strange excitement, and reckless and feverish, I wished the wind to howl more wildly, the gloom to deepen to darkness, and the confusion to rise to clamour. (1.6.14)
Jane claims that, because she came from an unpleasant home where she felt unwelcome, she is excited rather than depressed by her situation at Lowood, symbolized here by the windy chaos outside the window.
We’re not sure, however, if we should believe her; even though her life at Gateshead was unpleasant, any change is distressing, especially for a child, and maybe she is mourning for the home she had before, even if it wasn’t too great. Jane’s first comment on her homelessness makes us realize that she’s not always a completely honest narrator, and we might have to dig deep to figure out her real feelings.
