It seems to me she's encouraging someone to express himself : "spit them out", "show me who you are", though she admits it is "not as easy as it seems". Because it is far easier to walk, run, hear, talk... than to express yourself in an artistic way ("dream", "sing").
It is about creativity and art : "there is no rope, there is no line", that is : inspiration needs an object, something to begin with. We are nothing ("specks of dust in the sky") but we can "leave [something] behind" with art.
