Dreaming is one of the most mysterious and interesting experiences in our lives.

做梦是我们日常生活中最神秘也最有趣的经历之一。

During the Roman Era some dreams were even submitted1 to the Roman Senate for analysis and dream interpretation2. They were thought to be messages from the gods. Dream interpreters even accompanied3 military leaders into battles and campaigns！

在罗马时期，甚至会有一些梦境被递交到罗马元老院（一个审议的团体，它在罗马共和国与罗马帝国的政府中扮演着极其重要的角色）进行梦境分析与解析。因为在当时，“梦境”被认为是上帝想要向人类传递的信息。战时甚至会有解梦人陪同军事将领一起奔赴前线。

In addition to this， it is also known that many artists have received their creative ideas from their dreams.

除此之外，据说还有很多艺术家曾从梦境中获得创作的灵感。

But what do we actually know about dreams？ Here are some interesting facts about dreams：

但是我们对于梦境究竟能了解多少呢？这里有一些关于梦境的有趣事实：

1. You Forget 90% of Your Dreams 有百分之九十的梦境会被你遗忘

Within 5 minutes of waking half of your dream is forgotten. Within 10， 90% is gone.

在醒来的5分钟内你会忘掉一半的梦境；十分钟内，百分之九十都会被忘得一干二净。

2. Blind People also Dream 盲人也会做梦

People who become blind after birth can see images in their dreams. People who are born blind do not see any images， but also have vivid4 dreams involving their other senses of sound， smell， touch and emotion.

非先天性失明的人在梦境中也会看到一些意象。天生失明的人在梦中虽看不到影像，但也会有同样生动的梦境，包含着诸如声音、味道、触感和情感等感觉。

3. Everybody Dreams 每个人都会做梦

Every human have dreams （except in cases of extreme psychological disorder5）. If you think you are not dreaming—you just forget your dreams.

每个人都会做梦（除了一些极度心理紊乱者的案例）。如果你认为你不会做梦，那只是因为你已经忘掉了自己的梦。

4. In Our Dreams We Only See Faces That We Already Know

我们只会在梦境中看到我们见到过的面孔

Our mind is not inventing faces—in our dreams we see real faces of real people that we have seen during our life but may not know or remember. We have all seen hundreds of thousands of faces in our lives， so we have an endless6 supply of characters for our brain to use during our dreams.

我们的大脑无法臆造人的面孔，所以我们在梦境中见到的面孔都是在生活中见到过的，也许我们并不认识或记得那些人。我们大都在生活中见到过成千上万的人，所以在做梦时我们的大脑有无穷无尽的“人物资源”可以利用。

5. Not Everybody Dreams in Color 并不是所有人的梦境都是彩色的

12% of sighted people dream only in black and white. The remaining7 number dream in full color. Studies from 1915 through to the 1950s maintained8 that most of dreams were in black and white， but these results began to change in the 1960s. Today only 4.4% of the dreams of under-25 year-olds are in black and white. Recent research has suggested that those changing results may be linked to the switch from black-and-white film and TV to color media.

在视力正常的人中有百分之十二只做黑白的梦，其他人都是做彩色的梦。……
