I'm not sure I understand what you are stating here. The universe does in fact exist. When _your_ brain ceases to exist the universe will still be here, and my brain's interpretation of that universe is my consciousness.
i mean a universe with agency or any human-like properties. And more generally, we can't really know if the universe exists outside of us. We are limited to perceive that there exist regularities in the information content that our brains exchange with each other.
