'your' world (that is, your experienced reality) probably does both. There is always a bottom-up process orientation happening to resist the ground and gravity and that determines which hemisphere of your brain is getting more pressure-generated sensation and therefore more activity depending on the leg you're standing on. That orientation then also has to form the basis of a goal-oriented hand-to-ground stability that works in more of a top-down manner. For the large majority of humans that usually happens on the right side/left hemisphere
