Question

Quizplus · Accepted Answer

There is currently no scientific evidence to support the notion that learning can occur while a person is asleep, and the term "somnapaedia" is not a recognized or commonly used term in the field of sleep science. While certain sounds or stimuli may be processed by the brain during sleep, it is unlikely that any significant learning or information retention can occur without conscious awareness and attention.
