They found that people woken while their closed eyes made jerking movements recalled much more colourful and elaborate dreams than people woken during other stages of sleep.
他们发现相对那些从其它睡眠状态中醒来的人,从快速眼动睡眠状态中醒来的人更善于记住那些丰富多彩的梦境。
It is now believed that sleep acts as a sort of mental filing system, enabling the brain to sort relevant information that needs to be retained from useless information which can be discarded. This process may take place as memories are shifted from one part of the brain to others.
现在人们坚信,睡眠过程就像是一种记忆的归档系统。随着储存的记忆在大脑中进行位置转移,大脑从而对相关信息进行区分——摒弃无用信息,保留有用信息。
