中文摘要
背景： 梦境身体与物理身体之间的关系在睡眠与梦境研究中仍是一个未解问题。本研究在受控条件下考察了在快速眼动睡眠期间施加的躯体感觉刺激是否会调节相应的梦境内容。方法：采用被试内设计，我们比较了三种刺激模态——电肌肉刺激、直流前庭刺激和触觉振动——每种均与模态特异性假刺激配对。二十四名参与者完成了在睡眠实验室中的一晚适应夜，随后连续三个实验夜。在刺激或假刺激时段后的快速眼动睡眠唤醒后收集梦境报告，共获得120份报告。结果：在所有条件下均观察到身体感觉和动作的梦境融入；然而，广义线性混合效应分析显示，对于任何模态，刺激与假刺激条件之间均无统计学显著差异。在严格的假刺激对照条件下，未观察到可靠模态特异性梦境融入的证据。结论：这些发现并未证明存在稳健的刺激特异性效应，而是表明在实验室条件下，情境和预期相关影响对躯体梦境内容有实质性贡献，同时凸显了梦境融入研究中的方法学挑战。通过将多种躯体感觉刺激模态与严格的假刺激对照程序相结合，本研究为未来梦境融入和梦境工程研究提供了方法学基准。
英文摘要
The relationship between the dreamed body and the physical body remains an open question in sleep and dream research. This study examined whether somatosensory stimulation applied during REM sleep modulates the corresponding dream content under controlled conditions. Using a within-subject design, we compared three stimulation modalities-electrical muscular, galvanic vestibular, and haptic vibration-each paired with a modality-specific sham stimulation. Twenty-four participants completed one adaptation night followed by three consecutive experimental nights in the sleep laboratory. Dream reports were collected following rapid eye movement sleep awakenings after stimulation or sham periods, yielding a total of 120 reports. Dream incorporation of bodily sensations and actions was observed across all conditions; however, generalized linear mixed-effects analyses revealed no statistically significant differences between stimulation and sham conditions for any modality. No evidence for reliable modality-specific dream incorporation was observed under rigorous sham-controlled conditions. Rather than demonstrating robust stimulation-specific effects, these findings suggest that contextual and expectancy-related influences substantially contribute to bodily dream content under laboratory conditions while highlighting methodological challenges in dream incorporation research. By combining multiple somatosensory stimulation modalities with rigorous sham-controlled procedures, the present study provides a methodological benchmark for future investigations of dream incorporation and dream engineering.
