It requires focus for us to watch Netflix. How else are we able to explain our favourite characters or give the play-by-play of a scene or something that happened? Focus requires energy and clearly we'd have energy to pay attention to what's happening. If we didn't, we wouldn't know what's going on in a scene at all.
It requires focus to daydream as well. How else would we be able to describe what our ideal life is like or our dream home? I think that required a daydream session or two for us to focus on ironing out those details.
