Realities appear infinitely varied and individually created to me. With the provision for joining together into collectives of any size larger than one.
We no longer have a uniform reality on Earth. There are numerous groupings by numerous categories. Some certain universally agreed upon rules seem still to be in place, but even they show signs of bending, more and more.
Just look at some threads here where disagreement prevailed. How can bright people with the intention of coming to understanding, fail to do so? They are using different templates for their perceptions. They are looking from different places and seeing different things, even if their physical fingers point at the same thing. That is a product of personal choice.
One thing is pretty certain. while looking from 3D at this type of situation, we'll not get an accurate picture, because we have to model reality with our minds here. We have to shift our primary center of awareness into higher, lighter dimensions to actually see what comprises reality here in this world, and even then, the idea doesn't survive translation into our modeled descriptions we use to explain to one another.
It's probably a more useful thing to see how it is we act as creator for our own reality, than to work on understanding any models of reality, because since we are creating it, it's always changing.
