Hi:

Is it possible for a non-deaf person to have totally-silent dreams
[like watching TV on "mute"] due to an abnormality in his/her brain? I
imagine in those who are deaf due to damage to parts of their brains
would be just as deaf in their dreams as during wake -- even if the
deafness is non-congenital [i.e. it could happen in a perfectly healthy
adult in his/her mid 20s who previously had no difficulty in hearing].
AFAIK, the parts of the brain that perceive sounds in our dreams are
the same as the parts of the that perceive actual sounds. So, IIRC, if
the deafness is due to brain anomaly, the dreams will be just as silent
as the real world. 


Thanks a lot,
