Like with all dream interpretation it really depends on you and the interpretation is generally more reliable when coming from yourself or someone extremely knowledgeable about you for that reason.

From my personal point of view, not knowing you at all, I could make a succinct interpretation here that you may be either under-rewarding or over-rewarding yourself in real life, but likewise it could be about an opposite situation such as not being rewarded enough by others for something you may deserve credit or recognition for, especially since the dream seems to circle a little bit around you doing some novel-writing that you are keeping to yourself right now, but again, it could be relating to another part of your life too.
