在睡觉的时候,大多数人都有做梦的经历,在梦中有时能飞到天上,有时能潜游海底,有时还能变身成超人……这些奇特的做梦现象让人感觉十分神秘莫测。
那么,人们为什么会做梦呢?
在睡觉的时候,我们的大脑并没有完全的休息,部分脑细胞仍在辛勤的工作,这些脑细胞会把人们平时看到、听到、摸到、闻到的各种信息进行再次的加工、编排、处理,好像把一些图画、声音、味道组合成了特殊的“动画片”,于是就形成了梦境。做梦是人体一种正常的生理现象,由于睡眠时一些脑细胞正在休息,不能将大脑中的信息编排加工的完全按照符合现实,而是充满了很多随机的因素,所以梦境就出现了很多超自然的现象,比如做梦时感觉可以像小鸟一样自由的飞翔。
有时候梦境中还会出现一些非常令人害怕、恐惧的场景,这样的场景会把人惊醒,很多朋友小时候还被这样的“坏梦”吓哭过。我们把这种梦叫做“噩梦”,噩梦常一般会在10岁前出现,大多是儿童期正常特点,女孩比男孩更常见。如果偶尔做了噩梦,不要太紧张,也不要去刻意回忆恶梦的场景,起来喝口水转移下注意力,或闭上眼继续睡都可以。
梦可以预测未来吗?
很多人误以为梦的内容可以预示未来,认为有的梦是吉利、幸运的,而另一些则是凶险、不祥的,实际上梦境与未来没有任何联系,梦的内容也没有好与坏的区分,也不能预测未来。无论出现了什么样的梦境,都不必担心,也不要胡乱的联系和猜想,那只是我们的脑细胞在随意地“拍电影”而已。
做梦是人体一种正常的生理现象,没有梦反倒可能让身体出现一些问题。有科学家曾做过一些“阻断人做梦”的试验。通过检测人睡觉时候的脑电脑,一出现做梦的脑电波时,就立刻被唤醒,不让梦境继续,如此反复进行,结果发现,如果不让做梦会导致人体出现很多问题,如血压升高、脉搏加快、焦虑、紧张、易怒、感知幻觉、记忆力下降等。所以,正常的梦境活动对维持我们人体的正常功能还具有重要。
健康的人在整晚的睡眠中一般会做几次梦,为什么有人醒来时候感觉做了梦,有的人却感觉一晚上都没有做梦呢?
这与人们的睡眠周期有关,正常的睡眠周期主要分两个部分,一个是快速眼动睡眠期,另一个是非快速眼动睡眠期。科学家们观察到在快速眼动睡眠期人的眼球会发生快速转动,而快速眼动睡眠期则不会,而做梦只发生在快速眼动睡眠期。也就是说,人们在睡觉时候,有梦时段和无梦时段是交替出现的。当你在做梦的时段醒来时候就会感觉自己在做梦,有时能回忆到清晰的梦境,而在无梦的阶段醒来,就不会感觉到做梦。
虽然还至今还没有完全揭示梦的奥秘,但梦并非不神秘,是可认知的,通过大量的研究,科学家们已经发现了很多关于梦的机制,不必把做梦与任何神秘现象联系在一起,它只是一种正常的生理现象。
你有没有做过春梦呢 :)

不過我倒想起, 我以前小時候做得夢都很特別!
