Overview

Nightmare Disorder
Nightmare disorder involves repeated, disturbing dreams that cause significant distress or interfere with sleep and daytime functioning. Nightmares may lead to repeated awakenings, difficulty returning to sleep, fear of going to bed, daytime fatigue, or anxiety about sleep. Occasional nightmares are common, but frequent or persistent episodes may warrant evaluation for contributing psychological, medical, medication-related, or sleep-related factors.
Influenza
Influenza is a contagious respiratory illness caused by influenza viruses. It commonly develops suddenly and may cause fever, chills, cough, sore throat, muscle aches, headache, and marked fatigue. Some people, particularly young children, may also experience vomiting or diarrhea. Most healthy people recover without serious complications, but influenza can lead to pneumonia and other severe problems in older adults, young children, pregnant people, and individuals with certain chronic conditions or weakened immunity. Seasonal vaccination and appropriate infection-control measures help reduce illness and transmission.

Diagnosis

Nightmare Disorder
Nightmare disorder is diagnosed primarily from the history and pattern of recurrent disturbing dreams, awakenings, distress, and daytime impairment. A clinician may ask about sleep schedules, medications, substances, trauma, stress, mental health, and other sleep symptoms. A sleep diary can help document patterns. A sleep study is not routinely required but may be considered when another sleep disorder is suspected.
Influenza
Influenza can often be diagnosed clinically from symptoms and the pattern of illness during periods of active community transmission. Rapid influenza diagnostic tests may provide results quickly, although their ability to detect infection varies. Molecular tests, including rapid molecular assays and other laboratory methods, can provide more sensitive confirmation when testing is indicated. Testing is particularly useful when the result may affect treatment, infection-control decisions, or evaluation of people at higher risk of complications. The diagnosis should also consider other respiratory infections with similar symptoms.

Prevention

Nightmare Disorder
Occasional nightmares are common and cannot always be prevented. Maintaining a consistent sleep schedule, getting adequate sleep, managing stress, and avoiding excessive stimulation before bedtime may help promote healthier sleep. Addressing trauma, anxiety, or other psychological difficulties can be important when nightmares are recurrent. Reviewing medicines or substances that may affect dreams with a healthcare professional can also be useful.
Influenza
Annual influenza vaccination is an important measure for reducing the risk of influenza and its complications. Good hand hygiene, covering coughs and sneezes, improving indoor ventilation, and avoiding close contact with people who are ill can reduce transmission. People with influenza should stay home when sick when possible and follow local guidance about returning to normal activities. Higher-risk individuals should seek medical advice promptly when significant influenza symptoms develop because antiviral treatment may be most useful when started early.

Risk Factors

Nightmare Disorder
Risk factors include frequent stress or anxiety, traumatic experiences, disrupted sleep schedules, sleep deprivation, and some medicines or substances. Children commonly experience nightmares, and episodes can increase during periods of developmental or emotional change. People with post-traumatic stress disorder or other psychological conditions may experience recurrent distressing dreams. Persistent nightmares can also occur alongside certain sleep disorders.
Influenza
The risk of influenza is increased during periods when influenza viruses are circulating widely. Older adults, young children, pregnant people, and individuals with chronic heart, lung, kidney, metabolic, or neurological conditions may have a greater risk of serious complications. Weakened immunity can also increase risk. Close contact with infected people, crowded indoor environments, and inadequate ventilation can facilitate transmission. Lack of seasonal vaccination may increase susceptibility to circulating strains.
