Something Is Calling You Lyrics

Lyric discussion by BluesBender 

Cover art for Something Is Calling You lyrics by Norah Jones

Though this is my favorite song of Norah Jones in terms of music and the emotion/atmosphere that it carries, I am not entirely certain what this song really is about. I've seen people post some very insightfull things at lirics here. Does anyone have a clue on what this lyric is about?
