Dreams, embodiment & consciousness
Dreams, embodiment & consciousness
The
body of your dreams
Anil Ananthaswamy
New Scientist, 13 August 2011
This
article, based on research by Alan Hobson at Harvard and Ursula Voss at Bonn
University, discusses recent dream research. The suggestion here is that in
addition to the conventional view that dreams relate to everyday waking life,
there is a segment of dreaming that connects to representations of the body
that may not be currently realistic.
This latter hypothesis is derived from dream
research with paraplegics and with the deaf. Dream reports of subjects born
with paralysis had them walking, running and swimming as frequently as control
groups of normally active subjects. About 80% of deaf subjects could speak and
hear in their dreams. Voss notes the possibility that this dreaming was simply
based on observing people with normal movement and hearing, but argues for a
genetically determined ability to mimic activities such as movement and speech
in dreams. The lack of difference in experience of movement between paraplegics
and controls also appears to argue for this, given that something that was only
seen as being done by others would be expected to manifest less frequently than
something directly experienced as a part of waking life.
These findings
would appear to place a question mark over some versions of embodiment theory,
which tend towards consciousness arising mainly from bodily movement. While it
is likely that feedback from the body plays an important role, these findings
suggest that conscious experiences of movement are also hard wired into the
brain.
