Abstract
Lucid dreaming, the experience of being aware of dreaming in the dream, offers a unique window for neuroscientific research. In the last 50 years, the study of lucid dreaming has developed rapidly due to the advances in neuroscience, especially polysomnography and fMRI. This review highlights the neuroscientific basis of lucid dreaming about distinct neural features, varying from brain electrical activities to activated cortical regions and related substantial neural basis of lucid dreaming. Such results give us a whole picture of lucid dreaming from a neuroscientific perspective. Furthermore, lucid dreaming is related to high-level cognitive functions, such as metacognition, partly suggesting the neural mechanism of consciousness, as well as giving us a platform to delve further into it. Apart from basic studies, lucid dreaming has applications ranging from clinical therapy to motor skill training and human-computer interaction. These findings suggest the great potential of lucid dreaming in both neuroscientific research and everyday scenarios.
