A pilot study tested lucid dreaming treatment (LDT) for chronic nightmares. Twenty-three nightmare sufferers were randomly assigned to an individual LDT session, a group LDT session, or a waiting list. Twelve weeks later, nightmare frequency decreased in both treatment groups. Sleep quality and posttraumatic stress disorder symptom severity showed no significant changes. Becoming lucid during nightmares was not necessary for the reduction in nightmare frequency. The key therapeutic component—exposure, mastery, or lucidity—remains unclear.

A series of eight participants received a one-hour lucid dreaming treatment session for nightmares, including exercises and discussion of constructive solutions. Two months later, nightmare frequency decreased and sleep quality slightly improved, but there were no changes in state or trait anxiety. The treatment appears effective for reducing nightmare frequency, though the specific mechanism remains unclear.

Among 498 patients with diverse moderate-to-severe psychiatric disorders, those who also had nightmare disorder showed higher levels of psychopathology and personality pathology than those without nightmare disorder, with small effect sizes. No significant differences were found in coping strategies between the two groups. The findings suggest that nightmare disorder is linked to greater symptom severity in psychiatric patients.

Imagery rehearsal therapy (IRT) reduces nightmare frequency, nightmare distress, and general psychiatric symptoms in patients with a range of psychiatric disorders. In a trial of 90 patients, those who received six individual IRT sessions added to their usual treatment showed moderate improvements compared with those receiving treatment as usual alone. The benefits were largely sustained three months later. IRT involves patients changing the script of a nightmare into a new dream and practicing it during the day.

Two cognitive-behavioural self-help interventions for nightmares, imagery rehearsal and exposure, produced effects that were almost completely sustained 42 weeks after treatment ended. The initial improvements in nightmare measures persisted with effect sizes between 0.50 and 0.70. No differences in effectiveness were found between the two interventions. These long-term results suggest that nightmares can be effectively treated with targeted self-help approaches, and an internet-delivered intervention may serve as a good first step in a stepped-care model.

Imagery rehearsal therapy (IRT) and exposure to nightmare imagery, delivered as self-help treatments over six weeks, both reduce nightmare frequency and distress, improve subjective sleep quality, and lessen anxiety (after IRT) and depression (after exposure) compared to a waiting list. Keeping a nightmare diary (recording) also helps, though less so. IRT reduces nightmare frequency more than recording alone, while exposure reduces distress more. IRT produces faster reductions in diary-reported nightmares. The findings suggest that exposure to nightmare imagery may be the key therapeutic ingredient, with cognitive restructuring adding immediate benefits.

The DSM-IV-TR definition of nightmares is too narrow, as nightmares can involve emotions other than fear, such as anger or grief, and waking directly from a bad dream does not necessarily increase distress. Measuring nightmare frequency is problematic: polysomnography reduces nightmare frequency, retrospective reports underestimate it, and frequent nightmare sufferers may avoid daily logs. Idiopathic and posttraumatic nightmares differ, with posttraumatic ones linked to more and longer awakenings and both associated with periodic limb movements. Nightmares correlate with neuroticism and general psychopathology, and nightmare distress mediates daily impact. Imagery rehearsal therapy is the preferred cognitive-behavioral treatment, though no randomized controlled trial with an attention control group has been conducted. Nightmares should be treated as a separate, prevalent sleep disorder.
