I propose a narrative fabrication thesis of dream reports, according to which dream reports are often not accurate representations of experiences that occur during sleep. I begin with an overview of anti-experience theses of Norman Malcolm and Daniel Dennett who reject the received view of dreams, that dreams are experiences we have during sleep which are reported upon waking. Although rejection of the first claim of the received view, that dreams are experiences that occur during sleep, is implausible, I evaluate in more detail the second assumption of the received view, that dream reports are generally accurate. I then propose a "narrative fabrication" view of dreams as an alternative to the received view. Dream reports are often confabulated or fabricated because of poor memory, bizarre dream content, and cognitive deficits. It is well documented that narratives can be altered between initial rapid eye movement sleep awakenings and subsequent reports. I argue that we have reason to suspect that initial reports are prone to inaccuracy. Experiments demonstrate that subjects rationalize strange elements in narratives, leaving out supernatural or bizarre components when reporting waking memories of stories. Inaccuracies in dream reports are exacerbated by rapid memory loss and bizarre dream content. Waking memory is a process of reconstruction and blending of elements, but unlike waking memory, we cannot reality-test for dream memories. Dream experiences involve imaginative elements, and dream content cannot be verified with external evidence. Some dreams may involve wake-like higher cognitive functions, such as lucid dreams. Such dreams are more likely to elicit accurate reports than cognitively deficient dreams. However, dream reports are generally less accurate than waking reports. I then propose methods which could verify the narrative fabrication view, and argue that although the theory cannot be tested with current methods, new techniques and technologies may be able to do so in the future.
我提出了一个关于梦报告的叙述虚构理论,根据该理论,梦报告通常不是睡眠期间发生的经历的准确表示。我首先概述了 Norman Malcolm 和 Daniel Dennett 的反经验理论,他们拒绝了梦的传统观点,即梦是我们在睡眠中经历的并在醒来后报告的体验。虽然拒绝了传统观点的第一个主张,即梦是在睡眠中发生的体验,这是不可信的,但我更详细地评估了传统观点的第二个假设,即梦报告通常是准确的。然后,我提出了一个替代传统观点的“叙述虚构”观点。梦报告经常是由于记忆不佳、奇异的梦境内容和认知缺陷而被编造或虚构的。有充分的文献记载表明,在快速眼动睡眠初始觉醒和随后的报告之间,叙述可以被改变。我认为,我们有理由怀疑初始报告容易出现不准确的情况。实验表明,当报告对故事的清醒记忆时,受试者会合理化叙述中的奇怪元素,省略超自然或奇异的成分。梦报告中的不准确情况因快速记忆丧失和奇异的梦境内容而加剧。清醒记忆是一个元素的重构和融合过程,但与清醒记忆不同,我们无法对梦记忆进行现实测试。梦体验涉及想象元素,并且梦内容无法通过外部证据验证。有些梦可能涉及类似清醒的高级认知功能,例如清醒梦。与认知缺陷的梦相比,这类梦更有可能产生准确的报告。然而,梦报告通常不如清醒报告准确。然后,我提出了可以验证叙述虚构观点的方法,并认为,尽管该理论目前无法用现有方法进行测试,但新技术和技术可能在未来能够实现这一点。
