Heidi, a Girl of the Alps

I felt my tears come when I read the part of the novel in which Heidi started to sleep walk. She dreamed about her home high up in the mountain and her grandpa each night, only to wake up and know again that she was still in the city. Each night she went back to her grandpa in a dream, which made her walk out unconciously to search for things that she could never in her life get out of her head. She loved her grandpa and her home. It is one of the most charming pieces of literature I've ever read in my life.
