Nightware was approved by the U.S. Food and Drug Administration in 2020 to reduce sleep problems associated with nightmare disorder and nightmares related to PTSD, and so far has been prescribed primarily to veterans and people in the military. The device is not a treatment or cure for nightmares in the sense that it can eliminate them, but it interrupts the process so the sleeper is spared the stressful, emotionally difficult, and traumatic fallout of the dreams.
