“You Don’t Have to Live With Nightmares—Here’s Why”

In this powerful episode of Sleep Science Today, host Andrew Colsky sits down with Dr. Michael Nadorff, a leading sleep clinician and author of The Nightmare and Sleep Disorder Toolkit, to explore the often-overlooked world of nightmares.
 
Together, they unpack what actually causes nightmares—and why they’re far more than just “bad dreams.” Dr. Nadorff explains the strong links between chronic nightmares and mental health conditions such as PTSD, depression, and even increased suicide risk. Rather than viewing nightmares as a symptom to ignore, he makes the case that they deserve direct, targeted treatment.
 
Listeners will learn about evidence-based nightmare therapies, including imagery rehearsal therapy (IRT), lucid dreaming techniques, and emerging self-help approaches that empower individuals to actively change their dream content. Dr. Nadorff also discusses how therapists can better integrate nightmare treatment into mental health care—and how people suffering from recurring nightmares can begin addressing them on their own using practical tools from his research and writing.
 
This episode offers clarity, hope, and actionable insight for anyone haunted by nightmares—or supporting someone who is.

Join sleep expert Andrew Colsky as he sits down with Dr. Helene Emsellem, one of the nation’s leading sleep physicians, for a deep dive into how sleep changes across the lifespan—why teens can’t fall asleep, why retirees wake too early, and why medications aren’t the long-term solution most people think they are.
