梦带我们进入一个不同的现实，一个与清醒时的经历一样真实的幻觉世界。这些经常发生的怪异事件是人类睡眠的象征，但尚未得到充分解释。回顾性的梦境报告容易被扭曲和遗忘，这对梦境的神经科学研究提出了根本性的挑战。在这里，我们表明，熟睡且处于清醒梦中的个体（意识到他们当前正在做梦）可以感知实验者的问题并使用电生理信号提供答案。我们在 36 名个体的多导睡眠图验证的快速眼动 (REM) 睡眠期间实施了双向通信程序。有些人以前很少有清醒梦的经验，另一些人经常做清醒梦，还有一个人是经常做清醒梦的发作性睡病患者。在快速眼动睡眠期间，这些人表现出各种能力，包括对新信息进行真实的感知分析、在工作记忆中保存信息、计算简单的答案以及表达意志答复。他们的反应包括独特的眼球运动和选择性的面部肌肉收缩，6 名测试者在 29 次中正确回答了问题。由四个独立实验室小组记录的这些对互动梦的重复观察表明，可以实时询问梦的现象学和认知特征。这种相对未经探索的沟通渠道可以实现各种实际应用，并为梦的实证探索提供新策略。由于梦与人们报告梦之间的延迟，以及从睡眠到清醒状态的变化，对梦的科学研究受到了阻碍。为了克服这个问题，Konkoly 等人。研究表明，处于快速眼动睡眠状态的人能够感知并回答实验者的问题，从而能够就梦境进行实时交流。
Dreams take us to a different reality, a hallucinatory world that feels as real as any waking experience. These often-bizarre episodes are emblematic of human sleep but have yet to be adequately explained. Retrospective dream reports are subject to distortion and forgetting, presenting a fundamental challenge for neuroscientific studies of dreaming. Here we show that individuals who are asleep and in the midst of a lucid dream (aware of the fact that they are currently dreaming) can perceive questions from an experimenter and provide answers using electrophysiological signals. We implemented our procedures for two-way communication during polysomnographically verified rapid-eye-movement (REM) sleep in 36 individuals. Some had minimal prior experience with lucid dreaming, others were frequent lucid dreamers, and one was a patient with narcolepsy who had frequent lucid dreams. During REM sleep, these individuals exhibited various capabilities, including performing veridical perceptual analysis of novel information, maintaining information in working memory, computing simple answers, and expressing volitional replies. Their responses included distinctive eye movements and selective facial muscle contractions, constituting correctly answered questions on 29 occasions across 6 of the individuals tested. These repeated observations of interactive dreaming, documented by four independent laboratory groups, demonstrate that phenomenological and cognitive characteristics of dreaming can be interrogated in real time. This relatively unexplored communication channel can enable a variety of practical applications and a new strategy for the empirical exploration of dreams. Scientific investigations of dreaming have been hampered by the delay between a dream and when people report on their dream, and by a change in state from sleep to wake. To overcome this problem, Konkoly et al. show that individuals in REM sleep can perceive and answer an experimenter’s questions, allowing for real-time communication about a dream.
