Here's my take, and to keep it brief and not overanalyze or to quote each example I'll just say as a whole what your dream might represent.
I think that you have been presented with a situation that enables you to move forward in your waking life, perhaps a new job or a new relationship, or a change of residence. Something that you desire, yet are uncomfortable with the 'unknown' aspects of it. The What if's? Your heart is interested and you know the right thing to do, and you have come to terms with it, yet you haven't made a decision to move forward with this offer that is layed out for you.
