Awake in Deep Sleep: The case of lucid dreamless sleep

在意识研究中，关键目标之一是找出意识经验的主观特征。一个人有意识是什么样的？虽然我们可能会认为，要有意识，我们需要意识到一些东西，但有一些案例挑战了这一假设。清醒无梦睡眠（LDS），在睡眠中没有梦的意识体验，最近在寻求“纯粹”或“原始”意识体验的过程中变得流行起来。我的研究通过发现无内容意识体验的新数据来调查LDS。

In the study of consciousness, one of the key objectives is to find out what is the subjective character of conscious experience. What is it like for an individual to be conscious? While we might think that to be conscious we need to be aware of something, there exist some cases that challenge this assumption. Lucid dreamless sleep (LDS), the experience of awareness during sleep in the absence of dreams has recently gained popularity in the quest to find an experience of 'pure' or 'raw' awareness. My research investigates LDS by uncovering new data on contentless conscious experiences.
