The hallway is dark, the atmosphere tense—a noise echoes just meters away. A shadow emerges: an assassin with an evil grin, chasing you. But your legs feel glued to the ground; you can't run. As the knife plunges toward you... you wake up. It was just a nightmare. Yet its effects can be profoundly real: fatigue, stress, lingering fear—even depression. Can we influence or stop nightmares?
Given how disruptive nightmares can be, can dreamers learn to avoid or halt them mid-dream? Research is emerging, but studies point to lucid dreaming—the ability to recognize you're dreaming and take control without waking—as a promising avenue.
Nightmares are common, especially in children. Occasional ones rarely concern doctors, but frequent nightmares disrupting daily life may signal nightmare disorder, often linked to trauma, stress, or medications.
Proven treatments include medications and therapies, as outlined by the American Academy of Sleep Medicine in their 2010 analysis published in the Journal of Clinical Sleep Medicine.
Nightmares remain complex, notes Rachel Salas, MD, sleep disorders expert and associate professor of neurology at Johns Hopkins. We know they vary by sleep stage.
Most vivid dreams occur during REM sleep, where brain activity mimics wakefulness. People might dream of unusual acts, like stealing. REM begins about 90 minutes after sleep onset: breathing quickens, heart rate and blood pressure rise. Yet, the brain paralyzes muscles to prevent acting out dreams.

Lucid dreaming shows therapeutic potential, though not yet standard practice due to limited trials. A 2019 Frontiers in Psychology study supports its use for chronic nightmares.
To try it, use the "wake back to bed" method, per Sérgio Arthuro Mota-Rolim, researcher at Federal University of Rio Grande do Norte. Set an alarm 30 minutes before your usual wake time. When it rings, stay in bed, intending a lucid dream as you drift off.
This boosts odds, says Mota-Rolim—especially if you focus on it beforehand, as dreams are highly suggestible. In a nightmare, simply wake up. Or, stay dreaming, banish fear by recognizing no real danger exists. Some transform nightmares into pleasant dreams.
Lucid dreams are rare—most have fewer than 10 lifetime. Research hurdles include reliable induction methods, like 2014 studies on electrical stimulation frequencies. To explore further: Induce lucid dreams at will? A new method might allow this.
