1
In the third millenium BCE, Mesopotamian kings recorded and interpreted their dreams on wax tablets.
2
A thousand years later, Ancient Egyptians wrote a dream book listing over a hundred common dreams and their meanings.
3
And in the years since, we haven't paused in our quest to understand why we dream.
4
So, after a great deal of scientific research, technological advancement, and persistence, we still don't have any definite answers, but we have some interesting theories.
5
We dream to fulfill our wishes.
6
In the early 1900s, Sigmund Freud proposed that while all of our dreams, including our nightmares, are a collection of images from our daily conscious lives, they also have symbolic meanings, which relate to the fulfillment of our subconscious wishes.
7
Freud theorized that everything we remember when we wake up from a dream is a symbolic representation of our unconscious primitive thoughts, urges, and desires.
8
Freud believed that by analyzing those remembered elements, the unconscious content would be revealed to our conscious mind, and psychological issues stemming from its repression could be addressed and resolved.
9
We dream to remember.
10
To increase performance on certain mental tasks, sleep is good, but dreaming while sleeping is better.
11
In 2010, researchers found that subjects were much better at getting through a complex 3-D maze if they had napped and dreamed of the maze prior to their second attempt.
12
In fact, they were up to ten times better at it than those who only thought of the maze while awake between attempts, and those who napped but did not dream about the maze.
13
Researchers theorize that certain memory processes can happen only when we are asleep, and our dreams are a signal that these processes are taking place.
14
We dream to forget.
15
There are about 10,000 trillion neural connections within the architecture of your brain.
16
They are created by everything you think and everything you do.
17
A 1983 neurobiological theory of dreaming, called reverse learning, holds that while sleeping, and mainly during REM sleep cycles, your neocortex reviews these neural connections and dumps the unnecessary ones.
18
Without this unlearning process, which results in your dreams, your brain could be overrun by useless connections and parasitic thoughts could disrupt the necessary thinking you need to do while you're awake.
19
We dream to keep our brains working.
20
The continual activation theory proposes that your dreams result from your brain's need to constantly consolidate and create long-term memories in order to function properly.
21
So when external input falls below a certain level, like when you're asleep, your brain automatically triggers the generation of data from its memory storages, which appear to you in the form of the thoughts and feelings you experience in your dreams.
22
In other words, your dreams might be a random screen saver your brain turns on so it doesn't completely shut down.
23
We dream to rehearse.
24
Dreams involving dangerous and threatening situations are very common, and the primitive instinct rehearsal theory holds that the content of a dream is significant to its purpose.
25
Whether it's an anxiety-filled night of being chased through the woods by a bear or fighting off a ninja in a dark alley, these dreams allow you to practice your fight or flight instincts and keep them sharp and dependable in case you'll need them in real life.
26
But it doesn't always have to be unpleasant.
27
For instance, dreams about your attractive neighbor could actually give your reproductive instinct some practice, too.
28
We dream to heal.
29
Stress neurotransmitters in the brain are much less active during the REM stage of sleep, even during dreams of traumatic experiences, leading some researchers to theorize that one purpose of dreaming is to take the edge off painful experiences to allow for psychological healing.
30
Reviewing traumatic events in your dreams with less mental stress may grant you a clearer perspective and enhanced ability to process them in psychologically healthy ways.
31
People with certain mood disorders and PTSD often have difficulty sleeping, leading some scientists to believe that lack of dreaming may be a contributing factor to their illnesses.
32
We dream to solve problems.
33
Unconstrained by reality and the rules of conventional logic, in your dreams, your mind can create limitless scenarios to help you grasp problems and formulate solutions that you may not consider while awake.
34
John Steinbeck called it the committee of sleep, and research has demonstrated the effectiveness of dreaming on problem solving.
35
It's also how renowned chemist August Kekule discovered the structure of the benzene molecule, and it's the reason that sometimes the best solution for a problem is to sleep on it.
36
And those are just a few of the more prominent theories.
37
As technology increases our capability for understanding the brain, it's possible that one day we will discover the definitive reason for them.
38
But until that time arrives, we'll just have to keep on dreaming.

練習のヒント
この動画では、Amy Adkinsの話すスピードやトーンに注意しながら、shadow speechやshadowingを実践しましょう。特に、話すスピードが比較的ゆっくりで、感情も込められた表現が多いので、リズムに合わせて声に出してみてください。また、YouTubeで英語学習を通じて視聴した後、何度も繰り返し練習することで、自然に使えるフレーズが増えていきます。発音やイントネーションに注意し、自分の声を録音してみるのも良い方法です。これにより、自分の弱点を見つけやすくなります。
また、夢の内容についてのディスカッションをすることで、より多くのボキャブラリーを使った練習ができます。友人や言語交換パートナーと夢のテーマについて話すことで、英語スピーキング練習の幅を広げることができるでしょう。夢について考えたり話したりすることは、あなたの英語力を一層向上させる素晴らしい機会です。
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。
