I like to interpret the flow of imagination as a river that has impressions in it. I can play with that at will, be precise and specific or just observe what passes by, zoom out to a broader view. There is energy where is concentration. But if I am tired or bored and have to do repetitious tasks, it can be very distracting to dream away and I think this is important to consider for people that are creative. Many are diagnosed with ADHD or other conditions when they just haven't found out enough about themselves.
