If all exist as one, as you say, then we would also connect to the non-physical when we are awake.

Then there would be no difference between what appears to be physical and what appears to be non-physical.

We would be deeply connected to the non-physical when we are awake, then.

It would be all that we perceive.

If existence was maths, for example, we would take one particular formula and call it physicality. But it is actually no different from any other formula, as the elements are the same. It just appears to be different because you can make sense of the equation in a particular way. (You are approaching the same variables from a different perspective.)
