I love this song. I also think Noel has the perfect voice and tone to carry this tune beautifully. The Idler's dream part, in my understanding means that he's dreaming of this perfect person/girl to brighten his life, referring to HIMSELF as an idler; someone who doesn't do anything with their life. This girl he dreams of awakens him and makes him feel alive, and he's scared of losing the "dream" because she gives him feelings he would otherwise not have.
