那一刻似曾相识？

你有没有这么样的经历，一刹那脑子里突然闪过一种感觉，此情此景曾在哪里见过或已经经历过？我是经历过好多次，有时就是一句话，一个场景，有时是一个对话，或长或短。还曾经试想改变下，比如说：我知道我接下来要说什么，我想控制自己不这么说，但是从来没用成功过。。。

前些天终于知道这是一种心理学现象，很普遍。一下就是“科学解释”：

Deja-vu，原文为法语déjà vu，即视现象，似曾相识的感觉

这里有意思的是，“似曾相识”的科学解释：即视现象里提到的：有一首歌就叫deja-vu（Iron Maiden唱的），相当形象。以下是歌词：

When you see familiar faces
But you don’t remember where they’re from
Could you be wrong?


When you’ve been particular places
That you know you’ve never seen before
Can you be sure?


’Cause you know this has happened before
And you know that this moment in time is for real
And you know when you feel deja-vu


[Chorus:]
Feel like I’ve been here before
Feel like I’ve been here before
Feel like I’ve been here before
Feel like I’ve been here before


Ever had a conversation
That you realise you’ve had before
Isn’t it strange


Have you ever talked to someone
And you feel you know what’s coming next
It feels pre-arranged


’Cause you know that you’ve heard it before
And you feel that this moment in time is surreal
’Cause you know when you feel deja-vu


[Chorus:]
