While you might jest here, a similar thing does happen. If you have a helium balloon floating in a car, and you brake hard, the balloon goes backwards. The same happens with brains - if you have a car crash the brain hits the back of the skull, not the front.
Why? Because with the floating balloon, the heavier air moves forwards and pushes the lighter helium balloon backwards. Same with brain fluids, which are heavier than brains. Not sure if any of this applies to airships, whise ballonettes should constrain the differential gas mixtures.....
