Summary
AI-generated from the abstractIntegrated life episodes appear in only 1-2% of dream reports, based on new phenomenological data. This low rate conflicts with the replay of temporally sequenced memory seen in neuronal ensembles of some animals during sleep. The finding will limit emerging theories about memory reactivation during sleep and the role of sleep in memory consolidation.

Abstract
New phenomenological data demonstrate that integrated life episodes are incorporated in no more than 1-2% of dream reports. This appears to be at odds with the replay of temporally sequenced memory at the level of neuronal ensembles observed in some animals during sleep. This result will constrain emerging ideas on memory reactivation during sleep and the role of sleep in memory consolidation.
