Abstract
We discuss the relationship between sleep, dreams, and memory, proposing
that the content of dreams reflects aspects of memory consolidation taking
place during the different stages of sleep. Although we acknowledge the likely
involvement of various neuromodulators in these phenomena, we focus on the
hormone cortisol, which is known to exert influence on many of the brain
systems involved in memory. The concentration of cortisol escalates over the
course of the night's sleep, in ways that we propose can help explain the
changing nature of dreams across the sleep cycle.
