Neural correlates of self-generated imagery and cognition throughout the sleep cycle [PDF]
arXiv, 2016 Humans have been aware for thousands of years that sleep comes in many forms, accompanied by different kinds of mental content. We review the first-person report literature on the frequency and type of content experienced in various stages of sleep, showing that different sleep stages are dissociable at the subjective level.
