Mr. Rochester in Jane's mind

Jane advices to St. John to propose his love and affection to Rosamon although it's quite obvious. St. John opens up to Jane his reasons for holding back his love for Rosamond and says that she is a lovely woman, but is not fit to be the wife of a missionary. This barrier between their love resembles what Jane thought was impossible to overcome in her own life. Jane beleived that it was hopeless to end up with a higher class man such as Mr. Rochester; her dream also reminds her of Mr. Rochester, although Jane left him behind in Thornfeild, she is still attached to him and cannot forget the love they've shared. I am sure you have heard that people dream about what is mostly on their minds. Jane's desire to be with Mr.Rochester is not easily ignored or forgotten and is stucked in her mind as a reminder of what she has left behind -- romantic love that is not easily found.
