1
In the modern age, we've lost our reverence for the dream state, but more and more evidence is accumulating which suggests
2
that REM sleep was absolutely critical to the evolution of the special cognitive capacities that human beings evidence and our special creativity.
3
There are some people who believe that dreams really are just kind of a throwaway thing.
4
There are other people that think that dreams actually do serve a purpose.
5
Human REM sleep has a lot of very peculiar characteristics.
6
Every 90 minutes we go into REM sleep and our bodies become paralyzed, yet our brains are more activated than they are during waking consciousness,
7
and we're forced to watch these things we call dreams.
8
So why would Mother Nature do something like that?
9
The older models, when you look at Freud and you look at more Jungian thought, and there's still people who really use the Jungian thought of dream analysis,
10
is really that you analyze the dreams.
11
The dreams are there for a purpose.
12
For some people they say it's about wish fulfillment, it's about the things that you're never able to do in your day, you're actually fulfilling at night.
13
There other people who will say that it's actually telling you something.
14
If there's a lot of fear that's going on, if there's a lot of anxiety, it's manifesting itself in your nocturnal world so
15
that analyzing it can help to open up thoughts about what you need to do during the day.
16
So a lot of people who subscribe to the psychoanalysis, the onion thought, will really focus a lot on dreams, the meaning, and how it can be used to help you during the day.
17
Now if you go to more modern thought, there are some people who believe that dreams really are just kind of a throwaway thing.
18
They're just a way of your brain processing what's happened during the day but there's really no meaning to them.
19
A lot of imagery of just flashes of what happened.
20
There are other people that think that dreams actually do serve a purpose but what that purpose is we're not really sure.
21
So some people will believe
22
that it actually does have some psychological representation of what's going on in the day
23
but there's no need to sit and really analyze it.
24
Other people like myself think
25
that dreams are almost a reenactment of what happened during the day
26
but it's a way of you figure out your brain processing
27
to figure out what does it need to hold on to and remember and what can it just throw away.
28
So it's like your brain has a large filing cabinet
29
and it's opening up each drawer and it's taking in various images and memories from the day, consolidating what it needs to and puts it in whatever file
30
and then if there's something that doesn't fit in any of the files and doesn't really belong, you'll forget about it.
31
So it's a way of really getting a succinct way of storing things in your brain.
32
We see glimpses of these other possible worlds in our dreams.
33
What REM sleep normally does is it creates all kinds of bizarre ideas but all kinds of creative ideas as well.
34
When our ancestors in the Upper Paleolithic acquired greater access to the REM sleep state both during sleep and during waking consciousness,
35
it helped to fuel the onset of cumulative cultural evolutionary processes.
36
We know that REM sleep is especially important for human beings because it creates these dissociative experiences and associative experiences.
37
Dissociative experiences are something
38
that lots of us experience with this dreamy states where you feel like you're not quite yourself
39
and you're in like a deja vu experience
40
or a fluid mental state a flow state
41
but you're not sure what's real what's unreal
42
because you're immersed in all this imagery
43
but as you go through those kinds of dissociative states it starts to relax
44
or resolve into an associative state so that things
45
that were previously unrelated get combined and
46
when unrelated ideas combined creative innovative things happen and REM sleep promotes
47
that associative state big time our culture has lost its reverence
48
for the dream state whereas traditional cultures absolutely reverenced dreams
49
and I think some do references would help the culture
50
because it would create more openness to creativity
51
and disparate ideas this can help us solve the unknown unknowns
52
and help us get creative solutions to the problems people are facing.

シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
