The same state can be caught when you are lying in a hot bath, the brain vessels are relaxed, and if you chase a problem in your head, great solutions come up, the problem is often the same if you do not write it down right away then everything flies out of your head ..
I also had this - you can't figure it out without sherry. It's gone. And it was because I pissed and tried to be like that, "right" and want what "you have to want." I was afraid of myself. But you still live and draw conclusions, so you had to piss yourself off with the help of excessive alcohol consumption, which is harmful to our health.
I think this is due to alcoholic euphoria. It just seems to a person that what comes to his mind at this moment is terribly important and correct. In fact, it can be a complete mess, as well as the fact that in this state he is the smartest and most beautiful.
I have a hunch about this, in general, the bottom line is that the brain has two modes: focused and diffuse, focused is our constant mode, especially when we are engaged in, in fact, mental activity. But the diffuse mode is a more difficultly accessible state of the brain, in this we are during sleep, as well as, for example, during a run, in fact, no one wrote about alcohol intoxication anywhere, but probably also from this series)
The fact is that the focused mode implies the full activity of our neurons in conjunction with the frontal lobe of the brain - a kind of command center of our head. The main feature of the mode is complete control over thinking and, accordingly, over the variables of our thought process, everything that comes to our mind is the result of conscious thinking. When the brain enters the diffuse mode, the frontal lobe of the brain plays a lesser role, as well as actively less the number of neurons in the main part of the brain, the consequence of this is the accidental "digestion" of the recently assimilated material, in this mode, without realizing it, we can come to very sensible conclusions (Mendeleev, for example, his table just in this mode came to mind) or just to understand very difficult material.
In general, the competent use of brain modes can lead to very good success in mastering complex material related, for example, to the exact sciences.
I will give an example of use: after acquaintance with complex material / deep reflections / attempts to solve a difficult problem, go for a run / take a nap for half an hour or an hour / sip beer. The most it.
