My high level students in my lessons discovered how a new study shows that we could learn vocabulary while we are sleeping. This is great news for students struggling to learn a new language. It is also good for anyone who is trying to expand their knowledge of words. Researchers from the University of Bern in Switzerland have shown that it is possible to learn new information while we are sleeping deeply, and then recall this information when we need it after we wake up. This new information includes foreign language vocabulary.
