How you can go from watching videos of people using some new, special kind of dynamite on wild animals, to a walking through a schoolyard. How one minute you can be in a small room, arguing with (listening to) a bunch of people whose one point of agreement is futility, and the next minute you're wrestling someone to the ground while children are pouring over them to help you. It should be harder to pin someone who's channeling all their struggles into biting you.
Another thing about dreams. When someone says "My toes feel empty," it may not be a good itea to grab them by the shoulders and repeatedly slam their back into a wall. And why do all the walls people ever get slammed up against have that ring of molding about halfway up? Approximately shoulder-high to anyone and everyone whose luck brings their bodies in more contact with walls than might be considered The Norm.
