一千年之后，古埃及人写了一本关于梦的书，列出了一百多个日常的梦以及它们的解释。

精神上受到的压抑可以被理解和解答。

换句话说，你的梦也许是个大脑运转时的随机保护程序，所以大脑并不会完全停止运转。

1983年，一个关于梦的神经生物学理论提出逆向学习的概念，该理论认为我们在睡觉时，

那些无意识的内容可以反映出我们有意识的思想，

they also have symbolic meanings, which relate to the fulfillment of our subconscious wishes.

John Steinbeck called it the committee of sleep,

因此，当外界的输入低于一个特定水平时，例如你在睡觉时，

we still don't have any definite answers, but we have some interesting theories.

it's possible that one day we will discover the definitive reason for them.

the unconscious content would be revealed to our conscious mind,

We dream to forget.

我们为了保证大脑运转而做梦。

So, after a great deal of scientific research, technological advancement, and persistence,

所以，我们在经历了大量的科学研究、科技进步以及坚持不懈之后，

我们的大脑构造里有大约一万兆的神经连接。

leading some researchers to theorize that one purpose of dreaming is to take the edge offpainful experiences to allow for psychological healing.

leading some scientists to believe that lack of dreaming may be a contributing factor to theirillnesses.

事实上，他们比那些在两次之间醒着思考迷宫的人，
