0相信我们都曾疑问过关于为什么我们会做梦。关于这个问题有几种理论和解释，但没有确切答案。研究人员表示，梦没有明确的意义，并且是在睡眠大脑中发生的不合逻辑的活动。也有人说，梦对身体，情感和心理健康至关重要。让我们一起来看一下那些试图揭穿关于梦背后的奥秘的理论吧。
1、We Dream to Fulfil Our Wishes
Sigmund Freud says that dreams reveal a person`s thoughts, motivations, and unconscious desires. They are one way for people to satisfy their hidden urges and desires.
我们通过做梦来填充自己愿望
西格蒙德弗洛伊德说，梦揭示了一个人的思想，动机和无意识的欲望。它们是人们满足其隐藏的冲动和欲望的一种方式。
unconscious /ʌnˈkɒnʃəs/ 无意识的
unconscious of sb./sth. 未察觉到，未意识
He was quite unconscious of the danger. 他丝毫没有意识到危险。
2、We Dream to Remember
The researchers found that some areas of the memory are sharpened when people are asleep, and dreams are proof that their memories are being jogged.
我们通过做梦来记忆
研究人员发现，当人们睡着时，记忆的某些区域会变得尖锐，并且梦证明他们的记忆正在被唤醒。
jog /dʒɒg/ 常见的含义指“慢跑”，但在本文中指“唤起，提醒”
jog sb’s memory 唤起某人记忆
An old photo that might jog your memory.可能会唤起你记忆的旧照片
3、We Dream to Solve Problems
Some researchers have been led to believe that one purpose of dreaming is to help us solve the problems and challenges in our lives. Most experts believe that dreams are there to help us cope with stress and solve the problems facing us. (In 2010, researchers found that their subjects were much better at solving a complex 3D maze when they napped and dreamed of the maze before attempting it a second time. In fact, they were up to five times better than those who had only thought of the maze while awake and those who napped but didn’t dream about the maze. )
我们通过做梦解决问题
一些研究人员认为梦的一个目的是帮助我们解决生活中的问题和挑战。大多数专家认为，做梦可以帮助我们应对压力并解决我们面临的问题。(2010年，研究人员发现，他们的受试者在第二次尝试迷宫之前，如果打盹时梦到了迷宫，能够更好地解决复杂的3D迷宫问题。事实上，他们比那些只是在清醒时想到迷宫的人和那些打盹但却没有梦到迷宫的人要好五倍。)
purpose /ˈpɜ:pəs/ 目的；用途
The purpose of the book is provide a complete guide to the university.
本书旨在全面介绍这所大学。
on purpose 故意，有意的
He did it on purpose, knowing it would annoy her.
他明知会激怒他，却故意那么做。
4、We Dream to Keep Our Brains Working
The continual brain activation theory proposes that our dreams are as a result of our brain’s need to continually create long-term memories for it to function properly. Our dreams might be a temporary ”screen saver” to our brains, so they don’t completely shut down whenever we sleep.
我们通过做梦让大脑不停运转
持续的大脑激活理论提出，我们的梦是由于我们的大脑需要不断创造长期记忆才能使其正常运作。我们的梦可能是我们大脑的临时“屏幕保护程序”，所以每当我们睡觉时它们都不会完全关闭。
continual /kənˈtɪnjuəl/ 持续的，频繁的
I hate these continual argument. 我讨厌这些频繁的争吵。
continually /kən'tɪnjʊəlɪ/ 不断地，频繁地
New products are continually being developed.
新产品正源源不断地开发出来。
