“As I exclaimed ‘Jane! Jane! Jane!’ a voice – I cannot tell whence the voice came, but I know whose voice it was – replied, ‘I am coming: wait for me;’ and a moment after, went whispering on the wind the words – ‘Where are you?’
“I’ll tell you, if I can, the idea, the picture these words opened to my mind: yet it is difficult to express what I want to express. Ferndean is buried, as you see, in a heavy wood, where sound falls dull, and dies unreverberating. ‘Where are you?’ seemed spoken amongst mountains; for I heard a hill-sent echo repeat the words. Cooler and fresher at the moment the gale seemed to visit my brow: I could have deemed that in some wild, lone scene, I and Jane were meeting. In spirit, I believe we must have met. You no doubt were, at that hour, in unconscious sleep, Jane: perhaps your soul wandered from its cell to comfort mine; for those were your accents – as certain as I live – they were yours!”
Reader, it was on Monday night – near midnight – that I too had received the mysterious summons: those were the very words by which I replied to it.

Jane Eyre, Chapter 37. This passage describes the supernatural connection between Rochester and Jane. He recounts how he called out to her one night through his bedroom window and a voice answered to say they were coming. He feels that he and Jane had met in spirit. Jane confirms that she did indeed hear his voice from afar and spoke those words of reply. This shows that distance could not sever the physical bond between Jane and Rochester.
