Good sleep, good learning, good life is an article written by Dr Piotr Wozniak, the principal author of SuperMemo, which is the first SRS. The article describes the benefits of getting a good night's sleep has on learning. He talks about an interesting concept called free running sleep, napping and argues against sleep learning. It's a long read, but very helpful to serious learners of any kind.
I was wondering if any forum members have tried to learn in their sleep, and if so, was it beneficial?
