Evidence suggests continuity between cognition in waking and sleeping states. However, one type of cognition that may differ is episodic thoughts of the past and future. The current study investigated this across waking, NREM sleep and REM sleep. We analyzed thought reports obtained from a large sample of individuals (N = 138) who underwent experience-sampling during wakefulness as well as serial awakenings in sleep. Our data suggest that while episodic thoughts are common during waking spontaneous thought, episodic thoughts of both the past and the future rarely occur in either N2 or REM sleep. Moreover, replicating previous findings, episodic thoughts during wakefulness exhibit a strong prospective bias and frequently involve autobiographical planning. Together, these results suggest that the occurrence of spontaneous episodic thoughts differs substantially across waking and dreaming sleep states. We suggest that this points to a difference in the way that human consciousness is typically experienced across the sleep-wake cycle.
有证据表明，清醒和睡眠状态下的认知之间存在连续性。然而，有一种认知可能会有所不同，那就是过去和未来的情景记忆思维。本研究在清醒、非快速眼动睡眠和快速眼动睡眠期间对此进行了调查。我们分析了从大量个体（N=138）中获得的思维报告，这些个体在清醒期间和睡眠中的多次觉醒期间进行了经验采样。我们的数据表明，虽然情景记忆思维在清醒的自发思维中很常见，但过去和未来的情景记忆思维在 N2 期或快速眼动睡眠中很少发生。此外，与之前的发现相呼应，清醒时的情景记忆思维表现出强烈的前瞻性偏见，并且经常涉及自传体计划。总之，这些结果表明，自发情景记忆思维在清醒和做梦睡眠状态下的发生有很大的不同。我们认为，这表明在睡眠-觉醒周期中，人类意识的体验方式存在差异。
