This episode explores how sleep is a vital psychological and biological process, not just a period of rest. It explains why we sleep—restoration, emotional regulation, memory consolidation, and hormone balance—and breaks down the stages of sleep, including light sleep, deep sleep, and REM, where most dreaming occurs.

The episode also covers major theories of why we dream, from Freud’s unconscious desires to emotional processing and neural activation. Common dream themes like falling, being chased, or showing up unprepared are discussed as reflections of internal stress or emotions.

Sleep disorders such as insomnia, apnea, narcolepsy, night terrors, and REM behavior disorder are examined for their impact on mental health and daily functioning. The episode emphasizes the two-way link between sleep and mental well-being—poor sleep worsens mood and cognition, while good sleep improves emotional balance and resilience.

Finally, it offers practical sleep hygiene strategies, reminding us that sleep is an active process that shapes how we think, feel, and function.
