Third eye's perspective on a mind with two views

Resting brain signals are seldom understood. The unconscious brain's thoughts drive the conscious mind's actions. We register many a thing in the awake state, only to blissfully forget them when we need them the most. What compounds the issue is that the brain consumes energy during sleep, which, almost equals that consumed by the awake brain. This dual aspect and functioning of the brain was scientifically explained by Prof. Marcus E. Raicle in the Hoffman lecture given during the annual Science conference, 2008 at the University of Pittsburgh. His laboratory has done pioneering work on the functional MRI scanning ( glucose uptake by particular aspects of brain during sleep and active states) and found that the frontal ( that which regulates frontal and abstract thinking) and occipital( that portion of the brain that regulates vision) areas of the brain consume energy even during sleep states. The pioneering work to explain as to why the brain has to subsume so much energy is still in a nascent stage....Philosophically, this gives rise to two questions....does the sleeping visual brain consume so much to erase out the day's viewings to keep the soul unaffected by all that negativity that floats around? Does the thinking portion of the brain imbibe positivity from thought processing frontal brain in a sleeping state?
