While dreaming amputees often experience a normal body image and the phantom limb may not be present. However, dreaming experiences in amputees have mainly been collected by questionnaires. We analysed the dream reports of amputated patients with phantom limb collected after awakening from REM sleep during overnight videopolysomnography (VPSG). Six amputated patients underwent overnight VPSG study. Patients were awakened during REM sleep and asked to report their dreams. Three patients were able to deliver an account of a dream. In all dreaming recalls, patients reported that the amputated limbs were intact and completely functional and they no longer experienced phantom limb sensations. Phantom limb experiences, that during wake result from a conflict between a pre-existing body scheme and the sensory information on the missing limb, were suppressed during sleep in our patients in favour of the image of an intact body accessed during dream.
在做梦时，截肢者通常会体验到正常的身体形象，而幻肢可能并不存在。然而，截肢者的梦境体验主要是通过问卷调查收集的。我们分析了在 REM 睡眠期间从整夜视频多导睡眠图（VPSG）中唤醒的截肢患者的幻肢梦报告。六名截肢患者接受了整夜 VPSG 研究。患者在 REM 睡眠期间被唤醒，并被要求报告他们的梦境。三名患者能够提供梦境的描述。在所有的梦境回忆中，患者报告说，截肢的肢体完好无损，完全正常，他们不再感到幻肢的感觉。在我们的患者中，睡眠时会抑制由于预先存在的身体图式和缺失肢体的感觉信息之间的冲突而在清醒时产生的幻肢体验，转而支持在梦境中获取的完整身体的形象。
