A body of experimental research has aimed to investigate processes underlying dream formation by examining the effects of a range of pre-sleep stimuli and events on subsequent dream content. Given its ever-growing presence and salience in people's everyday lives, pre-sleep media consumption stands out as a key variable that could influence people's dreams. We conducted a scoping review to evaluate the experimental evidence of the effects of pre-sleep exposure to visual media on dream content. A systematic search on PubMed, PsycInfo, and Web of Science using terms related to moving visual media and dreams yielded 29 studies meeting the inclusion criteria. Overall, we found modest yet varied effects of pre-sleep exposure to visual media on dream content, with rates of stimulus-related incorporation ranging from 3% to 43% for REM dream reports, 4% to 30% for NREM sleep mentation reports, and between 11% and 35% for home dream reports. Our review highlights the large methodological heterogeneity and gaps across studies, the general difficulty in influencing dream content using pre-sleep exposure to visual media, and suggests promising venues for future research to advance our understanding of how and why digital media may impact people's dreams.
一系列实验研究旨在通过考察一系列睡前刺激和事件对后续梦境内容的影响，来探究梦境形成的潜在过程。鉴于睡前媒体消费在人们日常生活中日益普遍且显著，它成为一个可能影响人们梦境的关键变量。我们进行了一项范围综述，以评估睡前接触视觉媒体对梦境内容影响的实验证据。在PubMed、PsycInfo和Web of Science上使用与动态视觉媒体和梦境相关的术语进行系统检索，得到29项符合纳入标准的研究。总体而言，我们发现睡前接触视觉媒体对梦境内容有适度但多样的影响，快速眼动（REM）梦境报告中与刺激相关的融入率在3%至43%之间，非快速眼动（NREM）睡眠思维报告中为4%至30%，家庭梦境报告中为11%至35%。我们的综述强调了各研究在方法上的巨大异质性和差距，以及使用睡前接触视觉媒体来影响梦境内容的总体困难，并为未来研究提出了有前景的方向，以增进我们对数字媒体如何以及为何可能影响人们梦境的理解。
