You will often hear stuff like “We don’t use 80% of our brains” - That is completely untrue of course - that 80% is just doing “stuff” we don’t recognise - like keeping your heart beating and remembering to breathe. Also the “thinking brain” we are so proud of is in reality a very poor piece of computerisation operating on only a few bps and in serial cnfiguration. There is much which it cannot comprehend.
That’s where the “subconscious” comes in - it runs much more capacity, using parallel type processing and has much "RAM " it effortlessly “Puts the world in order” - How often do we “sleep on it” ? and in the morning the answer to our problem is just “there” - When we have a frustrating operation our conscious brain cannot solve, sometimes if we just have a “Cup of tea and a fag” we can return a few miinutes later and just “Do it”
Dreams seem to fall into a sort of interaction between the two parts - the conscious (which sleeps) and the subconscious (which does NOT !)
Just out of curiosity, has your “feeling” about the “Boris” issue changed over night ? Or resolved itself into an opinion perhaps ?
