不过人有时根本不需要真实的记忆，大脑就会自己制造一种熟悉的感觉，或者是对梦的记忆。当事情真正发生时，觉得好象在哪里经历过。其实是这件事勾起了自己对梦的回忆。

But some people don't need any kind of real memory. Their mind will just come up with a feeling of familiarity on its own, or they have some memory of a dream. When the thing actually happens, they feel like they've encountered it somewhere. Actually, the incident just evoked their memory of their own dream.
