Hmmm im gonna disagree
The dreaming world i would think is every bit as different as this world. This reality is coherent in the fact that it requires no mental effort to keep alive/real/constant (for the majority of people). A dreaming reality can never be permanently added on, in this world we build our lives and constantly update it. You can't do that in a dream, everything is created and destroyed every time you visit it. We are here now typing to each other questioning reality, and how real it is. This is the benchmark, for where everything stems off. We allways end up "here" regardless of any day or conversation.

In this reality there is no being God.
In this reality you can sit in your car and ponder reality.
What i think anyway, for now
