A nightmare, also known as a bad dream, [1] is an unpleasant dream that can cause a strong emotional response from the mind, typically fear but also despair, anxiety, disgust or sadness. The dream may contain situations of discomfort, psychological or physical terror, or panic. After a nightmare, a person will often awaken in a state of distress and may be unable to return to sleep for a short period of time. [2] Recurrent nightmares may require medical help, as they can interfere with sleeping patterns and cause insomnia.

Contents

Nightmares can have physical causes such as sleeping in an uncomfortable position or having a fever, or psychological causes such as stress or anxiety. Eating before going to sleep, which triggers an increase in the body's metabolism and brain activity, can be a potential stimulus for nightmares. [3]

The prevalence of nightmares in children (5–12 years old) is between 20 and 30%, and for adults between 8 and 30%. [4] In common language, the meaning of nightmare has extended as a metaphor to many bad things, such as a bad situation or a scary monster or person.

Etymology

The word nightmare is derived from the Old English mare , a mythological demon or goblin who torments others with frightening dreams. The term has no connection with the Modern English word for a female horse. [5] The word nightmare is cognate with the Dutch term nachtmerrie and German Nachtmahr (dated).

Originally, "mare" or "nightmare" referred more specifically to sleep paralysis, in which an experience of terror and paralysis during sleep can be associated with a sense of pressure on the chest and the dreamed presence of entities often pictured as demons, sometimes sitting on the chest. The words also referred to such a "demon," which was also referred to as a hag and the experience as being "hag-ridden." The meaning of "nightmare" had generalized from sleep paralysis to any bad dream by 1829. [1] In other languages, the word for "bad dream" similarly evolved in sense from words for "sleep paralysis," often with senses related to the pressure on the chest. For example, French cauchemar (the first element from old French chauchier "to press, trample," the second related to "mare"); Spanish pesadilla, from pesada "weight"; or Hungarian lidércnyomás, from nyomás "pressure."

History and folklore

The sorcerous demons of Iranian mythology known as Divs are likewise associated with the ability to afflict their victims with nightmares. [6] The mare of Germanic and Slavic folklore were thought to ride on people's chests while they sleep, causing nightmares. [7]

Signs and symptoms

Those with nightmares experience abnormal sleep architecture. The impact of having a nightmare during the night has been found to be very similar to that of insomnia. This is thought to be caused by frequent nocturnal awakenings and fear of falling asleep. [8] When awoken from REM sleep by a nightmare, the dreamer can usually recall the nightmare in detail. They may also awaken in a heightened state of distress, with an elevated heart rate or increased perspiration. [9] Nightmare disorder symptoms include repeated awakenings from the major sleep period or naps with detailed recall of extended and extremely frightening dreams, usually involving threats to survival, security, or self-esteem. The awakenings generally occur during the second half of the sleep period. [10]

Classification

According to the International Classification of Sleep Disorders-Third Edition (ICSD-3), the nightmare disorder, together with REM sleep behaviour disorder (RBD) and recurrent isolated sleep paralysis, form the REM-related parasomnias subcategory of the Parasomnias cluster. [11] Nightmares may be idiopathic without any signs of psychopathology or associated with disorders like stress, anxiety, substance abuse, psychiatric illness or PTSD (>80% of PTSD patients report nightmares). [12] As regarding the dream content of the dreams they are usually imprinting negative emotions like sadness, fear or rage. [4] According to the clinical studies the content can include being chased, injury or death of others, falling, natural disasters or accidents. Typical dreams or recurrent dreams may also have some of these topics. [13]

Cause

Scientific research shows that nightmares may have many causes. In a study focusing on children, researchers were able to conclude that nightmares directly correlate with the stress in children's lives. Children who experienced the death of a family member or a close friend or know someone with a chronic illness have more frequent nightmares than those who are only faced with stress from school or stress from social aspects of daily life. [14] A study researching the causes of nightmares focuses on patients who have sleep apnea. The study was conducted to determine whether or not nightmares may be caused by sleep apnea, or being unable to breathe. In the nineteenth century, authors believed that nightmares were caused by not having enough oxygen, therefore it was believed that those with sleep apnea had more frequent nightmares than those without it. The results actually showed that healthy people have more nightmares than sleep apnea patients. [15] Another study supports the hypothesis. In this study, 48 patients (aged 20–85 yrs) with obstructive airways disease (OAD), including 21 with and 27 without asthma, were compared with 149 sex- and age-matched controls without respiratory disease. OAD subjects with asthma reported approximately 3 times as many nightmares as controls or OAD subjects without asthma. [16] The evolutionary purpose of nightmares then could be a mechanism to awaken a person who is in danger.

Lucid-dreaming advocate Stephen LaBerge has outlined a possible reason for how dreams are formulated and why nightmares occur. To LaBerge, a dream starts with an individual thought or scene, such as walking down a dimly lit street. Since dreams are not predetermined, the brain responds to the situation by either thinking a good thought or a bad thought, and the dream framework follows from there. If bad thoughts in a dream are more prominent than good thoughts, the dream may proceed to be a nightmare. [17]

There is a view, possibly featured in the story A Christmas Carol , that eating cheese before sleep can cause nightmares, but there is little scientific evidence for this. [18] A single, biased study conducted by the British Cheese Board in 2005 argued that consuming cheese could trigger more vivid dreams, but this study was not backed up with sufficient research, and contradicts existing studies which found that consuming dairy products is associated with better overall sleep quality. [19]

Severe nightmares are also likely to occur when a person has a fever; these nightmares are often referred to as fever dreams.

Recent research has shown that frequent nightmares may precede the development of neurodegenerative diseases, such as Parkinson's disease and dementia. [20] [21] [22]

Treatment

Sigmund Freud and Carl Jung seemed to have shared a belief that people frequently distressed by nightmares could be re-experiencing some stressful event from the past. [23] Both perspectives on dreams suggest that therapy can provide relief from the dilemma of the nightmarish experience.

Halliday (1987) grouped treatment techniques into four classes. Direct nightmare interventions that combine compatible techniques from one or more of these classes may enhance overall treatment effectiveness: [24]

Post-traumatic stress disorder

Recurring post-traumatic stress disorder (PTSD) nightmares in which traumas are re-experienced respond well to a technique called imagery rehearsal. This involves dreamers coming up with alternative, mastery outcomes to the nightmares, mentally rehearsing those outcomes while awake and then reminding themselves at bedtime that they wish these alternative outcomes should the nightmares recur. Research has found that this technique not only reduces the occurrence of nightmares and insomnia [25] but also improves other daytime PTSD symptoms. [26] The most common variations of imagery rehearsal therapy (IRT) "relate to the number of sessions, duration of treatment, and the degree to which exposure therapy is included in the protocol". [27]

Medication

Trials have included hydrocortisone, gabapentin, paroxetine, tetrahydrocannabinol, eszopiclone, Sodium oxybate, and carvedilol. [29]

Post-traumatic stress disorder (PTSD) is a mental and behavioral disorder that develops from experiencing a traumatic event, such as sexual assault, domestic violence, child abuse, warfare and its associated traumas, natural disaster, traffic collision, or other threats on a person's life or well-being. Symptoms may include disturbing thoughts, feelings, or dreams related to the events, mental or physical distress to trauma-related cues, attempts to avoid trauma-related cues, alterations in the way a person thinks and feels, and an increase in the fight-or-flight response. These symptoms last for more than a month after the event and can include triggers such as misophonia. Young children are less likely to show distress, but instead may express their memories through play.

Sleep paralysis is a state, during waking up or falling asleep, in which a person is conscious but in a complete state of full-body paralysis. During an episode, the person may hallucinate, which often results in fear. Episodes generally last no more than a few minutes. It can recur multiple times or occur as a single episode.

Dialectical behavior therapy (DBT) is an evidence-based psychotherapy that began with efforts to treat personality disorders and interpersonal conflicts. Evidence suggests that DBT can be useful in treating mood disorders and suicidal ideation as well as for changing behavioral patterns such as self-harm and substance use. DBT evolved into a process in which the therapist and client work with acceptance and change-oriented strategies and ultimately balance and synthesize them—comparable to the philosophical dialectical process of thesis and antithesis, followed by synthesis.

<span class="mw-page-title-main">Nightmare disorder</span> Medical condition

Nightmare disorder is a sleep disorder characterized by repeated intense nightmares that most often center on threats to physical safety and security. The nightmares usually occur during the REM stage of sleep, and the person who experiences the nightmares typically remembers them well upon waking. More specifically, nightmare disorder is a type of parasomnia, a subset of sleep disorders categorized by abnormal movement or behavior or verbal actions during sleep or shortly before or after. Other parasomnias include sleepwalking, sleep terrors, bedwetting, and sleep paralysis.

Psychological trauma is an emotional response caused by severe distressing events, such as bodily injury, sexual violence, or other threats to the life of the subject or their loved ones; indirect exposure, such as from watching television news, may be extremely distressing and can produce an involuntary and possibly overwhelming physiological stress response, but does not always produce trauma per se. Examples of distressing events include violence, rape, or a terrorist attack.

Eye movement desensitization and reprocessing (EMDR) is a form of psychotherapy that is a recommended treatment for post-traumatic stress disorder (PTSD), but remains controversial within the psychological community. It was devised by Francine Shapiro in 1987 and originally designed to alleviate the distress associated with traumatic memories such as PTSD.

Acute stress reaction (ASR), also known as psychological shock, mental shock, or simply shock, as well as acute stress disorder (ASD), is a psychological response to a terrifying, traumatic, or surprising experience. The reactions may include but are not limited to intrusive thoughts, or dissociation, and reactivity symptoms such as avoidance or hyperarousal. It may be exhibited for days or weeks after the traumatic event. If the condition is not correctly addressed, it may develop into post-traumatic stress disorder (PTSD).

Complex post-traumatic stress disorder is a stress-related mental and behavioral disorder generally occurring in response to complex traumas.

A sympatholytic (sympathoplegic) drug is a medication that opposes the downstream effects of postganglionic nerve firing in effector organs innervated by the sympathetic nervous system (SNS). They are indicated for various functions; for example, they may be used as antihypertensives. They are also used to treat anxiety, such as generalized anxiety disorder, panic disorder and PTSD. In some cases, such as with guanfacine, they have also shown to be beneficial in the treatment of ADHD.

Prolonged exposure therapy (PE) is a form of behavior therapy and cognitive behavioral therapy designed to treat post-traumatic stress disorder. It is characterized by two main treatment procedures – imaginal and in vivo exposures. Imaginal exposure is repeated 'on-purpose' retelling of the trauma memory. In vivo exposure is gradually confronting situations, places, and things that are reminders of the trauma or feel dangerous. Additional procedures include processing of the trauma memory and breathing retraining.

Memory and trauma is the deleterious effects that physical or psychological trauma has on memory.

Cognitive behavioral therapy for insomnia (CBT-I) is a therapy technique for treating insomnia without medications. CBT-I aims to improve sleep habits and behaviors by identifying and changing thoughts and behaviors that prevent a person from sleeping well.

Cognitive processing therapy (CPT) is a manualized therapy used by clinicians to help people recover from posttraumatic stress disorder (PTSD) and related conditions. It includes elements of cognitive behavioral therapy (CBT) treatments, one of the most widely used evidence-based therapies. A typical 12-session run of CPT has proven effective in treating PTSD across a variety of populations, including combat veterans, sexual assault victims, and refugees. CPT can be provided in individual and group treatment formats and is considered one of the most effective treatments for PTSD.

Management of post-traumatic stress disorder refers to the evidence-based therapeutic and pharmacological interventions aimed at reducing symptoms of post-traumatic stress disorder (PTSD) and improving the quality of life for individuals affected by it. Effective approaches include trauma-focused psychotherapy as a first-line treatment, with options such as cognitive behavioral therapy (CBT), prolonged exposure therapy, and cognitive processing therapy (CPT) demonstrating strong evidence for reducing PTSD symptoms.

Childbirth-related post-traumatic stress disorder is a psychological disorder that can develop in women who have recently given birth. This disorder can also affect men or partners who have observed a difficult birth. Its symptoms are not distinct from post-traumatic stress disorder (PTSD). It may also be called post-traumatic stress disorder following childbirth (PTSD-FC).

Post-traumatic stress disorder (PTSD) can affect about 3.6% of the U.S. population each year, and 6.8% of the U.S. population over a lifetime. 8.4% of people in the U.S. are diagnosed with substance use disorders (SUD). Of those with a diagnosis of PTSD, a co-occurring, or comorbid diagnosis of a SUD is present in 20–35% of that clinical population.

MDMA-assisted psychotherapy is the use of prescribed doses of MDMA as an adjunct to psychotherapy sessions. Research suggests that MDMA-assisted psychotherapy for post-traumatic stress disorder (PTSD), including complex PTSD (C-PTSD), might improve treatment effectiveness. In 2017, a Phase II clinical trial led to a breakthrough therapy designation by the U.S. Food and Drug Administration (FDA) for potential use as a treatment for PTSD.

WWII lasted from September 1st, 1939 until September 2nd, 1945. The death toll during WWII has been estimated to be between 35,000,000 and 60,000,000. However, the exact number is unknown. With all those fatalities, it should not be surprising that it left so many lasting effects on the survivors. There have been many terms for these lasting effects over the decades. These terms include, but are not limited to, shell shock and combat fatigue. In 1980, the diagnosis of PTSD was added to the newly published DSM 3.

Narrative Exposure Therapy (NET) is a short-term psychotherapy used for the treatment of post-traumatic stress disorder and other trauma-related mental disorders. It creates a written account of the traumatic experiences of a patient or group of patients, with the aim of recapturing self-respect and acknowledging the patient's value. NET is an individual treatment, NETfacts is a format for communities.

Imagery Rescripting is an experiential therapeutic technique that uses imagery and imagination to intervene in traumatic memories. The process is guided by a therapist who works with the client to define ways to work with particular traumatic memories, images, or nightmares.
