Now that I think this phenomenon is very clearly articulated, I wonder if it isn't possible to have multiple 'top [ideas] in your mind' or 'ground states'. It could be simply a matter of training your brain to have a strong stack for traversing the two or maybe three key areas or contexts that you're thinking about. I.e., one solution is: make sure your top idea or ground state really is what you want. Another solution may be: train a better graph visitation algorithm. However, trying to train one's unconscious may be sort of like quantum physics -- i.e., for lack of a better word: difficult. Perhaps you can just throw two or three main things you'd like to see happen into a collider, go to sleep or take a shower, and see what happens. But it may be possible to train yourself to think with very clear visitation between different contexts consciously, and actually have this process bubble down into the unconscious and take hold there too. I.e., hack your unconscious. Arguably it's the same sort of thing we do when we try to offload parallel processing onto a GPU or cloud (though in those cases the hardware is much more specific).
