Dreams - why do we have them? Do they mean anything? Is there such a thing as a dream in which the events seen by the dreamer come true? Such questions have interested people for thousands of years. Scientific advances in the past few decades have revealed more about the physical process of sleep, but they still don't offer any final answers to the many questions about dreams that continue to puzzle us. Everyone dreams - it's just that some of us can't remember doing so. Recordings of human brain waves show that we all go into dream mode when we fall asleep. We dream for most of the night, but we're only able to remember our dreams if we happen to wake up while we are still in REM (Rapid Eye Movement) sleep. This is when we dream.
梦，我们为什么会做梦？梦有意义吗？真的有梦中所见的事成为现实这种事吗？几千年来这些问题一直让人们感兴趣。过去几十年的科学发展对睡眠的自然过程有了较多的认识，然而对于与梦有关的诸多问题依然没有提供最终的答案，这些问题还要继续困惑我们。 人人都做梦——只不过有些人不记得做过梦罢了。人类脑电波的记录显示我们所有人入睡后就进入梦境。整个夜晚的大多数时间我们都在做梦，但只有当我们处在REM (眼睛迅速转动) 睡眠阶段时醒来，才会记住所做的梦。眼睛迅速转动阶段便是我们做梦的时候。
