We all have a secret second consciousness living in our brain that we don't know about - a prisoner of our bodies with no autonomy of their own. The hypnogogic jerk you sometimes get before you fall asleep is him trying to seize control of the body while you're vulnerable and your guard is down.
It's funny how such a disgustingly violent incident, a scene of utter chaos that the operators had to endure for close to a full day, and one that the parents will suffer through for the rest of their life, can be so systematically boiled down to a few default terms regurgitated over and over and over by the media, as though each and every incident can be treated with a simple copy/paste and change of the date. There is not a single word in that article that can even remotely convey the horror of that scene, nor frighten the average driver to keep two hands on the wheel and concentrate on the road.
