Dreaming of a battle means you are stressed out by your currently workload. Even a small task such as emptying the trash becomes a battle between of you doing it rather than letting the garbage bin overflow. Whatever is stressing you out at the moment, try turning it off by taking your mind off it. Thinking about it does not make it better nor does it make it go away. Relax for a day or two, and tackle the task at hand by giving it your full attention.
