If you read any Carlos Castaneda he describes numerous experiences where he has perceived from two places at once while standing and also while carrying out other activities such as walking etc etc. I do believe it is possible. "Human potential is nothing to sneeze at", as he would put it:)


   One such insident described by Don Juan (the sorcerer whom apparently trained Carlos Casteneda) involves a situation where Don Juans teacher pushed him into a fast moving river in order to shock his perception and perform an amazing feat. After he was pushed into the river he ended up perceiving himself running along side the river as he was swimming. His veiw bounces back and forth between the two perceptions. He ended up getting trapped on an island in the middle of the river. He spent days there where apparently he expereinced the final perfect control of his dreaming body after his benefactors teaching method of pushing him into the river. He traveled with his "second body" for a week straight until he was rescued.

   Their are many other expereinces which he writes about involving OBE in general, though they call it the second body. I highly reccomend readinf the material to anyone interested in OBE.
