许多人都认为,一夜无梦是一件幸福的事。研究者却发现梦可以锻炼大脑的思维能力。接受临床实验的人群中有一部分在即将进入梦眠状态即被强行叫醒,结果他们即使在学习中勤奋努力也难以取得良好的成绩。梦对人脑的积极作用与计算机对数据的处理有相同之外,它使大脑皮层之间的联系进入一个更为良好的阶段。 梦对保持人类的精神健康也起着非常积极的作用。许多患有慢性忧郁症的病人就长期被混乱的梦或缺乏梦的异常睡眠所困扰。当他们进行了通过电脑调节脑波的睡眠治疗后,病情有不同程度的好转。那么,为什么有些人不能做梦或者说完全回忆不了梦境呢?这是受到无线电波的干扰导致的。如果消除了这些干扰,4-6天后就可以重新享受做梦的惊险和乐趣。

做梦对人有许多好处,做梦可以锻炼脑的功能。做梦是人脑的一种工作程序,对大脑白天接受的信息进行整理,大脑白天不能处理的信息能在梦境中得到很好的处理,白天苦苦思素而无法解决的难题能在夜晚的梦境中迎刃而解。 根据脑电图的测试也发现,人脑在做梦时的活动是相当强烈的,我们能够从做梦时测到快速的、紊乱的脑电波,其强度有时会超过觉醒时的强度。从这一点来看,做梦是锻炼人脑功能的一种自身需要。
经常听到有人抱怨"作了一夜的梦,一宿没休息好","晚上梦多,简直没有睡着"。那么真的是做梦耽误了休息吗?做梦是大脑不曾休息或休息不好的表现吗?这种观念是不对的,做梦并能回忆梦境并非睡眠不深的指标,也不能说做了梦就表示没有睡好。实际上,做梦是一种生理现象,不管你有没有梦的回忆,你每天晚上毕定要做4~5回梦。因此说整夜做梦或没有做梦都不现实,也谈不上梦多梦少。有研究表明,梦感与失眠的程度没有必然的联系。也就是说,有无梦感和梦感的程度均不能作为失眠与否及失眠程度的客观指征。

那么,为什么会有前面的抱怨呢?有学者通过调查分析,认为与下列因素有关:
(1)睡眠知识及睡眠与梦感的关系所知甚少。
(2)与人的情绪状态有关。
(3)对自己的健康过分关心,对梦感过分关注,导致梦感增强。反过来又加重对健康的担心,对失眠的恐惧,以至形成恶性循环。
(4)在REM睡眠中和后期觉醒更可能回忆起梦的内容。
(5)个体功能状态差异,不同的个体的梦感不同,甚至同一个体在不同时期,另外,部分人虽然没有明显的失眠,但是在夜里做梦后白天就感到有气无力,其实这是一种心理因素所致。做梦者总是把梦中的内容和自己心情不愉快的事情联系在一起,使思想负担加重,情绪受到压抑,从而出现种种不适现象。

做梦本身对人及睡眠都有一定的益处,除非你夜夜惊梦不得安眠,日间有明显嗜睡,影响正常的工作和生活,则应找医生看看,寻找原因并进行治疗。

有一次做恶梦,一女鬼骑在我身上掐我脖子,我使劲一翻身,硬是把恶梦做成了春梦。从此在也没做过恶梦。
