There is little evidence that Don Juan did what he is said to have done, and that he existed at all. At most, "Juan Matos" is a pseudonym.
A Carlos Castanedas writes of Jon Juan in several books. Castanedas' father was a goldsmith and watchmaker. Carlos studied painting and sculpture at the National Fine Arts School of Peru. Many documented sides to Castanedas' history go counter to what Castanedas tells himself about his life.
Serious analytical criticism of Castaneda's books emerged after 1975, for he had actually been sitting in a library when his journal said he was squatting in Don Juan's hut - (WP, "Carlos Castanedas")
Sound dreaming can help a man out. And whay may we see?
Human beings may be seen within luminous shapes that resemble brilliant, huge eggs of a sort. The eggs of heaven are bigger than the human bodies and float around them.
Within a huge egg is its "yolk" and a tiny germ-spot within that "yolk" again. Human perception is assembled within the golden germ-spot within the bright egg. The tiny germ may have the brightest glow within, in that side to life.
When the germ spot (assemblage point) is placed as usual, in a regular and carefully regulated position, perception and awareness appear normal, judging by the standard behaviour of those phenomena that are studied.
But when the assemblage points (germ) and surrounding glowing sphere (yolk) are differently placed that otherwise, eccentric behaviour can be observed in someone, or very unfamiliar sights. The greater the displacement of the assemblage point from its habitual position, the more unusual the consequent behaviour. There are some possibilities:
