"they accept the (socially conditioned) notion that the dream world is reality itself"
The problem is to define the word "reality"...
I have a very simple experience that I feel anyone can identity.
Many of you will know the colour test... it doesn't matter if you think it means something or not... it makes you choose colours by order of preference

okey... I know that depending on my mood, or how my life is... I don't see the colours the same way, and this happens to everyone.
For me sometimes the orange square is "uglier" and sometimes not. It's really different when I see it. Same with other colours. The computer screen is the same, the light of the room is the same but you perceive it different. What is different is yourself and that makes them different for you.
If you don't believe it, take the test (I have no connection with that site... and don't care about the explanations)...
then a week after... or even after some certain change in your life... do it again and you'll choose different colours.
And if you remind this you'll realize the colours are different for you in the second time. And you don't need a test for that... when there's a change in you, you see it all different, even just how colours are.
There's a "objective way" of how colours are...??? My perceived blue is not your perceived blue.
