In regards to the rabbits in the hutch- were they 'Tiny' rabbits? Maybe they represent yourself as a child? If you thought they smelled bad, that could mean that in your present life they are 'yucky' so instead of delving in there and helping them (and freeing them) you are cautious (maybe the same in therapy, cautious to explore your childhood further)??

Your Dads greasy hair may represent him being 'dirty' (IRL as well as the dream, sorry if that sounds harsh, i hope you get what i mean)?
