I dont think "The Art of Dreaming" needs a defender at all
I read the book many times and it always struck me how my experience corresponds to the one described (to the certain extend). There are lot of things in the field of lucid dreaming that can not be described in words. So Carlos did it in the best way one could. And i tell you i read a lot of books on the subject.
It's a pity you took the book this way.
Sometimes circumstances like lighting in photography. The same thing might look different depending on where lights are.
