We may be able to learn vocabulary while sleeping

We could learn vocabulary while we are asleep. This is great news for language learners and word lovers. Researchers showed it is possible to learn new information while sleeping deeply, and recall this information later. The researchers did tests to see if a person can remember new words and their translations while they were asleep. The researchers said our sleeping brain is much more aware than we thought.

A researcher said, "language areas of the brain and the…brain's…memory were activated" after a person wakes up. These areas of the brain remember vocabulary during sleep. During deep sleep, our brain is active for about half a second. It then switches off for half a second. The active state is called "up-state". This is when our brain could learn new vocabulary. More research is needed to be sure that we can learn vocabulary while sleeping.
