Dreaming during anaesthesia: a scoping review

Listen to this summary

This scoping review aims to synthesize existing evidence on the phenomenon of dreaming during anaesthesia, exploring its frequency, characteristics, predictors, outcomes, and neural correlates. The authors found that dream recall varies significantly between experimental and clinical settings, with a predominance of pleasant dreams and specific associations with certain anaesthetic agents. They highlight the need for standardized research approaches to address gaps in knowledge regarding definitions, assessment methods, and the potential therapeutic implications of anaesthesia dreaming.
