Problems are solved by sleeping
Posted on June 13th, 2009 by MichaelBBC:
Sleeping on a problem really can help solve it, say scientists who found a dreamy nap boosts creative powers.
They tested whether “incubating” a problem allowed a flash of insight, and found it did, especially when people entered a phase of sleep known as REM.
Volunteers who had entered REM or rapid eye movement sleep – when most dreams occur – were then better able to solve a new problem with lateral thinking.

Proceedings of the National Academy of Sciences has published the US work.

It is very interesting to see how brain works when in sleep.
Delta sleep is the most relaxed and recovered sleep.
REM sleep is the shallow sleep, but produce creative thinking that you can remember when you wake up.

Sounds good, but like Wisdom comes with Age. It just is not that simple. I agree with the principle but I look at it from a different perspective. Pardon me if this seems like an over-simplification but for a few moments see it this way.
It’s like the Bank, if you have deposited it, the knowledge, it’s available for withdrawal when it’s needed. But no input, no availability.
I agree sleep is probably the ideal way to move away from the question and let the resolution quietly present itself.
Things take time and consciously rushing consideration of any matter is not as good as; putting the Requisition into the Necktop Computer and let the Response come. How many times have we experienced that can’t recall the name moment, and shortly after, it comes to mind.
Sure sleep is great in this context but, as I have tried to describe, you can achieve good results while you’re awake, by just leaving it alone in your mind to find a Better View, an answer.
But importantly, the data has to be in Necktop or you can’t draw upon it. Like the body clock, which is marvellous, set the time as you go to bed or set the question, but then sleep, leave it alone. Trust the staff in the Computer Room. They’re good.
