I can see it now, drifting inside the cerebral hemispheres:
If weight transfer is pused to the left, the right side's brain cells is empty, thus amnesia occurs, along with color blind, and the inability to daydream.
Conversely, if the left side is empty, the person will speak gibbrish, spell numbers incorrectly, and can't walk straight.
I was going to say about the left brain controls the right body, but it will certainly confuse people.
Overall - Drifting inside the brain- bad?
