You see there are assumptions in your first paragraph that I have found to be false so I'm going to ignore that if that is the foundations of what you said
What I meant to say in that first paragraph; it is not so much that the brain can break the laws of physics, but rather information stored in the brain can be processed in new ways that are conceptually not exactly a part of space-time. For example, I can imagine I have imaginary wings and I then fly to the core of the sun. These physical actions are not possible in space-time. There so many violations of physical law. But in the realm of making information combinations, this statement is possible. All I did was combine three memories of provable space-time things; wings, flight, and the sun's core, but in a way they are not meant to be, thereby making space and time appear disjointed by my claim; not by the book. If space and time were not connected as space-time, the limitations of the laws of physics and space-time would not exist, opening more options.
Fictional writing is not constrained to just space-time connections, but it can make animals talk, since both animals and human talking are both data we can find in space-time, but not in that combination, unless we loosen the tether of the space-time rules.
All Innovation, at one point in time, is often outside the box of what is known and provable, at a point in time. Once it is proven, it is added to space-time knowledge base; real. But before proof, even though it worked in the lab and is already real, the mind of the majority will assume it is imaginary. But in reality, the defenders of the pace-time knowledge base are the one's stuck in their imagination, since they cannot see the future, when it proves out. The creator has seen the future, as their present, but the present needs more proof to see that future.
If the brain could only process reality data, as is known, all we would have is memory but no way to exceed it. Like the Koala Bear we would simply do what we do, never able to think outside the box. Thinking outside the box requires a way to generate new combinations, from space-time and sensory data, that may not go together based on what is known. This adds complexity and is 2nd law driven.
