先前的实验结合了认知技术和睡眠中断，在1周或更长的训练期内，在诱导家中清醒梦（LD）方面相对成功。在这里，我们诱导LD在一个单一的实验室午睡会议配对认知训练与外部刺激。参与者在早上7：30或11：00来到实验室，在多导睡眠图设置期间，他们被提供了关于清醒梦的信息。在睡前20分钟，实验者以1分钟的间隔交替播放音频和视觉提示。参与者被要求练习一种批判性自我意识的精神状态，每次注意到一个线索时，观察他们的想法和经历。这个过程将线索与训练过的心理状态联系起来。随后，参与者被允许小睡90分钟，并在REM睡眠期间呈现音频和视觉线索，以激活梦中的自我意识并引起清醒。对照组遵循相同的程序，但在睡眠期间没有提示。所有参与者都被指示通过向左和向右看4次（LR信号）来发出他们清醒的信号。信号验证的清醒梦（SVLD）被认为是观察到LR信号并且参与者报告变得清醒的梦。在2个午睡时间内，该方案在50%的暗示参与者中诱导了SVLD。在睡眠期间没有提示的情况下，参与者SVLD率为17%。值得注意的是，3名成功参与者之前从未经历过LD，表明该方案可能对一般人群有效。这一目标清醒度再激活协议的噩梦治疗的影响进行了讨论。
Previous experiments combining cognitive techniques and sleep disruption have been relatively successful in inducing at-home lucid dreams (LD) over training periods of 1 week or more. Here, we induce LD in a single laboratory nap session by pairing cognitive training with external stimulation. Participants came to the laboratory at 7:30 a.m. or 11:00 a.m. and during polysomnography setup were provided with information about lucid dreaming. For 20 min prior to sleep the experimenter played alternating audio and visual cues at 1-min intervals. Participants were instructed to practice a mental state of critical self-awareness, observing their thoughts and experiences each time they noticed a cue. This procedure associated the cues with the trained mental state. Subsequently, participants were allowed 90 min to nap, and the audio and visual cues were presented during REM sleep to activate self-awareness in dreams and elicit lucidity. A control group followed the same procedure but was not cued during sleep. All participants were instructed to signal their lucidity by looking left and right 4 times (LR signal). Signal-verified lucid dreams (SVLDs) qualified as dreams in which the LR signal was observed and the participant reported becoming lucid. Across the 2 nap times, this protocol induced SVLDs in 50% of cued participants. In the absence of cueing during sleep, participant SVLD rate was 17%. Of note, 3 successful participants had never before experienced a LD, suggesting this protocol may be effective across the general population. Implications of this Targeted Lucidity Reactivation protocol for nightmare treatment are discussed.
