a little experiential time might be of use here. just watch your life, your daydreams, your speech, whatever for a while and see how many interesting things your nervous system can deal with aside from the whole dreaming vs. reality stuff.
I have had many converstaions o the nature of reality and come to the conclusion we live completely in our mind, we have very little physical space, since the world has no existance, and verything we see has been filtered through our mind and therefore greatly distirted and subjuective, so reality can not be defined as no one has the same perecpetions and reality as anyone else:D
What exactly are ‘we’ trying to define here? We live in our minds is already a definition of reality. You’ve also already implied that there is a mind-independent world, but it’s a bit trickier than that. Rather than saying our view of the world is distorted or subjective, why not say that we describe that world through particular positions and for particular purposes and that that is what we should be doing. The problem with trying to define the way the world is, isn’t about our problems in seeing the world as it is, it is in defining the world in one description and only one description, the way the world really is. That makes no sense to me. Better to have multiple descriptions for multiple perspectives and purposes.
