No, I think that the truly true truth is that the world is outside us, and we are physical beings that exist inside reality.

The universe is outside us, and we are made of the universe, and our minds are like a computer.

The computer thinks thoughts inside of its CPU.

We think thoughts inside of our brain.

But outside our brain is true, raw reality. It is beyond our mortal senses often, thus we might think that the world is within us. But it is not.

There is not a matrix reality running inside our head.
We live in the real thing. The true reality is outside us, and we are part of it, but we do not create it.

We are mere animals, evolved chemical-reactions that have become intelligent, but not intelligent enough to truly comprehend the reality of reality.
