No insult taken.  I'm not a sleep expert, so your criticisms are probably
sound.

You are probably right.  I may be citing pathological conditions.
Occassionally, though, I am semi-aware of body postion, etc. during dreaming 
and can, to a *very limited* degree, alter it.  Now that I think about it, it 
does sound like a sleep disorder...

Actually, since it mainly deals with drawing, the book doesn't emphasize 
hemispheres so much as modes of perception.  To a certain degree, it 
recognizes that the question of lateralization and specialization in the 
brain is a messy question.

Regarding my theory- we can theorize all day about the causes of myoclonic 
spasms, but, without experimentation, they'll have to remain an unexplained 
nervous hiccup.
