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.

他們發(fā)現(xiàn)相對那些從其它睡眠狀態(tài)中醒來的人，從快速眼動睡眠狀態(tài)中醒來的人更善于記住那些豐富多彩的夢境。

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.

現(xiàn)在人們堅信，睡眠過程就像是一種記憶的歸檔系統(tǒng)。隨著儲存的記憶在大腦中進行位置轉(zhuǎn)移，大腦從而對相關(guān)信息進行區(qū)分——摒棄無用信息，保留有用信息。
