有些研究梦境的人把梦里出现的事情日后成为事实的梦,认为和预感、潜意识有关。预知梦的特点是,大部份都是预演第二天的情况较多。另外,预知梦是以自己为主角的较多。
有一部份的精神分析学者对有没有预知梦抱持着怀疑甚至是否定态度。认为他们梦里出现的事,之后变成事实只是做梦者的错觉而已。譬如说,曾有一位男子诉说,在梦中发现每日经过的一座木桥全部漆成了白色,次日发现桥果真成了白色。他非常惊奇。实际上数月前桥已重新漆成白色,只不过他路过时未加注意,但白色的桥已不自觉印入脑内。在梦中,白天未加注意的事情不知不觉显现了。所以才出现此梦境。
此外,还有一种与预知梦有点类似而令人容易混淆的现象,叫「似曾相识」或是「既视感」(deja
vu)。许多人或多或少都会有此经验,有时发生某些事的时候,人和人之间似乎有熟识的感觉,或对身边一景一物也似乎很熟悉,甚至接下来的对话和行对都是预料之中。有时更差点以为自己真的有超能力可预知未来。
但有研究报告指出,这种现象是大脑某半边处理信息的速度稍为快过另半边的生理原因所造成的。在美国的一项调查指出,似曾相识是很普遍的经验,而且有此经验的女性多过男性,年轻人又比老年人更常有似曾相识的经验。
现代则研究认为,人从清醒状态进入睡眠状态或从睡眠状态变成清醒状态都要经历一个过渡时期。这个时期大脑皮层的神经细胞常处于不完的抑制状态,在生理学上叫做催眠状态。此时身体内外的各种刺激就会引起与平时不一样的脑内反应,从而出现梦境。因此,梦境的出现离不开两个条件,一是大脑处于催眠状态,二是外界或身体内部存在着刺激。例如睡眠中不慎将两脚伸出被子外,因双脚受寒的刺激,就会产生赤脚渡河或光脚在雪地上奔走等的梦。
我就做过
在前面一天做梦
后在某一天里面情景出先梦里面情景
我在百度别的知道里面也看到这样问题
好象有说空间问题
就是我们提早到了后面空间
就象放电影
我们先看了后面电影
在有回到前面电影里面去在放回到后面去
就象有些人认为的
时间和空间是可以折叠的
而不是一条线的
直线的
就比如从广州到北京铁路要经过什么什么站
而某些人认为可以广州站下站就是北京站
之间路折叠了
