This is consistent with my prejudice. You may have access to emotions and memories that are masked when awake, but you are not going to find a super computer in there. Just a dream state, unmanaged thoughts. And this is why your brain paralyses your body when you are asleep, so that you don’t physically act out what you are dreaming.
Why would the brain evolve in such away that its best cognitive functioning is not available to the conscious mind? It’s when you are awake and acting that you need your best game. Cognitive ability does not come free. From an evolutionary POV the human brain is very expensive. It’s a huge liability in terms of energy expense, vulnerability and the time needed to develop it. The presence of occult cognitive powers doesn’t make any sense to me
