==================
It's not always the case that people cannot hear in their sleep--depends on 
how deeply they are "under". Some doctors think that people in some coma 
states can hear people talking around them and what is being said. More 
research is needed.
Are people still doing the satori tank thing? I was just trying to recall th 
eother day what these were called......these aimed at total sensory 
deprivation, right?
