The Purpose of REM Sleep
Dr. Gina Poe explains that the second half of the night, or REM sleep, is crucial for building new schema and resolving emotional aspects of memory. This period helps separate the emotional intensity of memories from the semantic facts, allowing for better recall without reliving the pain. Lack of quality REM sleep can lead to heightened anxiety and difficulty in distancing oneself from immediate emotions.In this clip

What is the difference between early night REM sleep and late morning REM sleep in the episode Dr. Gina Poe: How To Get Better Sleep And Boost Your Learning, Memory & Energy | Mel Robbins Podcast and the clip The Purpose of REM Sleep?
Is it correct that sleep is divided into two main stages, Non-Rapid Eye Movement (NREM, deep sleep, non-dreaming) and Rapid Eye Movement (REM, dreaming), and that NREM sleep is further divided into alpha, theta, and delta stages?
