One of the curious things I noticed many years ago was how much we agree on the appearance of the world. While there is a huge variation in emphasis and interpretation, we have no problem driving down the street. Other’s reality doesn’t cause the roads to change appearance continually as we go by.
This points to a shared reality. Modern science takes the approach that the physical world is real and we interpret it subjectively with our brains. But when we recognize that the world arises from and within consciousness, this points to a deeper shared reality.
