  Missing the point but hitting it anyway

Via ScienceDaily:
Hypnopedia, or the ability to learn during sleep, was popularized in the '60s, with for example the dystopia Brave New World by Aldous Huxley, in which individuals are conditioned to their future tasks during sleep. This concept has been progressively abandoned due to a lack of reliable scientific evidence supporting in-sleep learning abilities.
It was popular well before the '60s. As soon as recorded sound and radio became practical, sleep learning was tried and explored. Gernsback loved the idea. Huxley was writing in 1938, not 1968.

It was also popular in the '40s.



Reluctantly back to the article.....
A study published this August 6 in the journal Scientific Reports by researchers from the ULB Neuroscience Institute (UNI) shows that while our brain is able to continue perceiving sounds during sleep like at wake, the ability to group these sounds according to their organization in a sequence is only present at wakefulness, and completely disappears during sleep.
Based on experience, this isn't quite incorrect but it misses the point. The ability to create a structure DOESN'T disappear.

I wrote a few years ago:
I always run a playlist of old-time radio shows during sleeptime. Usually I'm awake for the first 30-minute show, then fade out during the next one. Most of these shows are thoroughly familiar, but I try to keep a fresh episode at the start to snatch my brain away from whatever idiot stuff I was worrying about in the day.

Several times I've dropped off during a familiar episode, then popped back up for unknown reasons. This in/out process enabled me to note the scenery and characters generated by the mind in both modes.

In wake mode, familiar episodes always repeat the location and characters that I 'built' the first time I heard the episode; and obviously use the story that was in the script.

I dropped down into sleep while 'in' the familiar location. In early sleep the ear circuit is still connected, so I was hearing at least part of the dialog. The in-sleep version of the location and characters and story was ENTIRELY DIFFERENT from the familiar waking version. The dream-generator instantly wrote its own houses and terrain, its own characters, and its own STORY LINE, to fit the words that were filtering inward. Needless to say, all of these were considerably more interesting and original than the waking version.
Thoroughly familiar sound was reaching consciousness in dreamworld, and the dream scripter was creating a fresh structure around the sound instead of using the familiar waketime structure.

In the context of sleep learning, the judgment reached by the article is still valid. The goal of sleep learning is to organize the info in a way that can be retained and reused in waketime. You can't reuse the dreamtime structure, so for this purpose it doesn't exist.

** Footnote: Ralph Slater, the hypnotist mentioned in the picture, had his own radio show. Only one episode is online. The "hypnotism" is highly dubious; mainly the show paid ordinary people to humiliate themselves in public.
