Nightmares aren’t just bad dreams—they’re a powerful window into the brain’s stress system, trauma pathways, and emotional memory. In this episode of Sleep Science Today, host Andrew Colsky sits down with Dr. Courtney Worley, a double board-certified clinical psychologist and behavioral sleep medicine specialist, to reveal what nightmares really mean and—more importantly—how to treat them.

Dr. Worley breaks down the surprising science behind nightmares, why they’re so common in PTSD, and the reasons many people get stuck in repeated dream patterns. Drawing from her acclaimed book, The Nightmare and Sleep Disorder Toolkit, she shares practical strategies anyone can use to reduce nightmare frequency, retrain the brain’s fear response, and finally reclaim restful sleep.

You’ll learn:

• Why nightmares happen and the brain systems involved

• How trauma and PTSD reshape nighttime imagery

• Which treatments actually work (including imagery rehearsal therapy)

• The specific skills Dr. Worley teaches her patients

• When nightmares signal a bigger sleep disorder

• How addressing nightmares improves overall mental health

If you or someone you love struggles with disturbing dreams, night terrors, or PTSD-related sleep disruption, this episode offers expert-backed solutions—and hope.
