the 3d absolutely has to obey the 4d.
ever heard of the "the universe can't exist without us being consciously aware of it" ?
basically if we aren't here to acknowledge something, technically it never happened/doesn't exist. "if a tree falls down in a forest, and nobody was there to hear it, it didn't make a sound" is true because...a "sound" is defined as something we can hear. without the presence of ears being there to acknowledge the sound did it really make a sound? or just release a pattern of vibrations?
note: this is just a philosophical theory , still quite interesting.
without awareness there is no "reality". awareness is reality. consciousness is reality.
what you are consciously acknowledging will absolutely be the thing to exist. the 3d simply cannot exist without the 4d. it is not a separate entity, the 3d is quite literally a mirror standing infront of your 4d. and the rest of the world is behind it. what your 4d is, the 3d reflect for the rest of the world to see, as neville has said
