Reality is not any thing. It's just appearances without a substance. You can't find a ground to our so called"physical world " because every ground would need another ground to ground it..at infinitum =there is no ground to reality =reality is just appearance of reality without a reality to that appearance. Now think of an example of an "appearances " without a "ground" or a"substance " to them? ....dreams . Therefore.."Reality " is a dreame. Which means it's an appearance without any actual substance to it which does NOT mean it's not there..the dream is there but it's just a dream!!.

You missed my point. My point is that there is no difference between reality and dreams to begin with. Dream us reality. Reality is dream. There is no difference. That doesn't mean it's not there..that mean they are the same and our distinction between them is baseless in the first place.
