Understand and Use Dreams to Learn and Forget

Episode 5 Feb 1, 2021 1h 16m 19 insights
This episode is all about the two major kinds of dreams and the sorts of learning and unlearning they are used for. I discuss REM-associated dreams that control emotional learning and their similarity to various trauma treatments such as ketamine and EMDR. I also discuss Non-REM dreams and their role in motor learning and learning of detailed, non-emotionally-laden information. I relate this to science-backed tools for accessing more of the types of sleep and learning people may want. Other topics are listed in the time stamps below.

Actionable Insights

1. Prioritize Consistent Sleep Duration

Strive for a consistent sleep duration each night (e.g., 6 hours every night) rather than varying total sleep time, as regularity is more important for learning and performance than simply maximizing duration.

2. Master Sleep for Emotional Unlearning

Implement and manage sleep protocols (e.g., morning light, evening light, food schedule) to ensure consistent sleep, as it is crucial for emotional unlearning and overall psychological well-being.

3. Ensure Sufficient REM Sleep

Prioritize getting sufficient REM sleep, especially towards morning, as it helps uncouple emotional load from challenging daytime experiences by allowing processing without fear or anxiety, preventing emotional irritability and catastrophizing.

4. Boost Motor & Detail Learning

Engage in motor skill learning (e.g., new dance moves, exercise, playing piano) and detailed information acquisition during the day, as slow-wave sleep (which dominates early in the night) is crucial for solidifying these skills and details.

5. Utilize NSDR for Relaxation

If you wake up in the middle of the night or feel anxious, use Non-Sleep Deep Rest (NSDR) protocols to relax your body and brain, which can help you fall back asleep and restore energy.

6. Incorporate Resistance Exercise

Engage in resistance exercise (not necessarily right before bed) to increase the percentage of slow-wave sleep, which aids motor learning and the acquisition of fine detailed information.

7. Avoid Sleep Disruptors (Alcohol/THC)

Avoid alcohol and THC (and similar substances) before sleep, as they disrupt the natural sleep architecture, depth, and sequencing of slow-wave and REM sleep, preventing truly deep restorative sleep.

8. Manage Serotonin Supplements

Be cautious with serotonin-boosting supplements (like tryptophan or 5-HTP) for sleep, as they might disrupt the natural timing of REM and slow-wave sleep, potentially leading to early waking.

9. Prevent Nighttime Waking (Fluids)

Avoid drinking excessive fluids right before bed to prevent waking up in the middle of the night due to a full bladder, which disrupts sleep.

10. Don’t Catastrophize Bad Sleep

Avoid catastrophizing occasional bad nights of sleep; instead, focus on adjusting and getting back to a consistent sleep schedule without accumulating sleep anxiety.

11. Consider EMDR for Trauma

If experiencing specific trauma, consider EMDR (Eye Movement Desensitization Reprocessing) therapy with a certified clinician, as lateralized eye movements can suppress amygdala activity and help uncouple emotional load from traumatic memories.

12. Explore Ketamine for Acute Trauma

In specific, acute trauma scenarios, ketamine-assisted therapy (under strict medical supervision) can be used to prevent intense emotional attachment to traumatic experiences by blocking NMDA receptors.

13. Induce Lucid Dreaming (Cue)

To potentially induce lucid dreaming, create a visual cue (e.g., write/draw a red apple) and look at it before sleep for several consecutive days, aiming to recognize it within a dream to gain awareness or control.

14. Manage Unwanted Lucid Dreaming

If frequently overwhelmed by lucid dreaming, aim for consistent sleep duration (e.g., 6 or 7.5 hours) that aligns with the end of 90-minute ultradian cycles, rather than waking mid-cycle, to potentially reduce its occurrence.

15. Keep a Dream Journal

Keep a dream journal by noting sleep/wake times and any dream recall upon waking (or later in the day) to explore and potentially understand your dreams.

16. Supplement with Athletic Greens

Consider taking Athletic Greens once or twice a day to cover basic nutritional needs and support microbiome health with vitamins, minerals, and probiotics.

17. Supplement with Electrolytes (Element)

Drink Element (electrolytes) dissolved in 16-32 ounces of water first thing in the morning and during physical exercise to ensure adequate hydration and electrolyte balance, which is critical for brain and body function.

18. Use Waking Up App for Meditation

Utilize the Waking Up app for meditation, mindfulness, yoga nidra, or NSDR protocols to place the brain and body into different states, restore cognitive and physical energy, and explore different types of meditation.
