Why Do We Have Nightmares?

Nightmares can feel overwhelming, but understanding the connection between emotional memory and sleep helps manage them.This video explores why we experience bad dreams and how the brain processes emotional memory during REM sleep. By examining the biological roots of these nocturnal experiences, we can better understand why specific themes recur and how they impact our overall rest.For those seeking relief, we provide an educational guide on using Imagery Rehearsal Therapy to change how you react to recurring nightmares. This technique offers a practical way to improve sleep quality by rewriting the narrative of your dreams, giving you more control over your nightly rest.Subscribe for more scientific breakdowns of the human mind, and let us know in the comments: what is the most common theme you notice in your own dreams? 📚 Sources / References American Academy of Sleep Medicine.
