What happens to our brain when we sleep? Are we ever really fully asleep? If so how is it that some individuals end up doing extraordinary things when they are?
Or can it be the case that perhaps the brain never fully goes to sleep and that in some individuals there is a disconnect between the sleeping part of their brain and the active part of their brain so that the two become confused?
