A nightmare is a disturbing dream associated with negative feelings, such as anxiety or fear.
Nightmares are common, and
occasional nightmares usually are nothing to worry about. However,
they may become a problem if you have them often and they disrupt
your sleep or cause you to fear going to sleep.
A diagnosis of nightmare disorder is only made if nightmares cause ongoing distress or problems with daytime functioning. Nightmares may begin in children between 3 and 6 years old and tend to decrease after about age 10. Until age 13, boys and girls appear to have nightmares in equal numbers. At age 13, nightmares seem to be more prevalent in girls than boys. Some people have them as teens or adults or throughout their lives.
Nightmare disorder is referred to by
doctors as a parasomnia — a type of sleep disorder that involves
undesirable experiences that occur while you're falling asleep,
during sleep or when you're waking up.
Nightmares usually occur during the stage of sleep known as rapid eye movement (REM).
You normally go through four to six sleep cycles a night, cycling through the sleep stages in about 90 minutes. Your REM stage lengthens with each cycle, from several minutes in the first cycle to up to an hour in the last. You're more likely to have a nightmare in the second half to the last third of your night.
A nightmare may involve these features:
Your dream seems vivid and real, often becoming more disturbing as the dream unfolds Your dream story-line is usually related to threats to your safety or survival Your dream wakes you You feel scared, anxious, angry, sad or disgusted as a result of your dream You feel sweaty or have a pounding heartbeat, but do not leave the bed .You can think clearly upon awakening and can recall details of your dream Your dream occurs near the end of your sleep time Your dream keeps you from falling back to sleep easily You may have nightmare disorder if, in addition to the above: The sleep disturbance causes significant distress or problems with functioning during the day Medications or physical or mental disorders do not adequately explain the fact that you have nightmares.
Children's nightmare content varies with age, typically becoming more complex. While a young child might dream of monsters, an older child might have nightmares about school or difficulties at home.
Nightmares are only considered a disorder if disturbing dreams cause you distress or keep you from getting enough sleep. Nightmares can be triggered by many factors, including: Stress. Sometimes the ordinary stresses of daily life, such as a problem at home or school, trigger nightmares. A major change, such as a move or the death of a loved one, can have the same effect. Trauma. Nightmares are common after an accident, injury or other traumatic event.
are prominent in post-traumatic stress disorder (PTSD).
Sleep deprivation. Changes in your schedule that cause irregular sleeping and waking times or that interrupt or reduce the amount of sleep can increase your risk of having nightmares.
Some drugs — including certain antidepressants, blood pressure medications, beta blockers, and drugs used to treat Parkinson's disease or to help you stop smoking — can trigger nightmares. Substance abuse. Alcohol and illegal drug use or withdrawal can trigger nightmares. Scary books and movies. Reading scary books or watching scary movies, especially before bed, can be associated with nightmares.
Some medical conditions and mental health disorders as well as other sleep disorders can be associated with having nightmares. For instance, anxiety can be associated with a higher likelihood of recurrent nightmares.
Nightmare disorder may cause:
Excessive daytime sleepiness, which can lead to difficulties at school or work, or problems with everyday tasks, such as driving and concentrating Problems with mood, if the anxiety from the dream continues to bother you Resistance to going to bed or to sleep for fear you'll have another bad dream.
TREATMENTS AND DRUG-
Treatment for nightmares isn't usually necessary. If the nightmares are causing you distress and interfering with your daytime functioning, talk to your doctor. The cause of the nightmare disorder helps determine treatment. Medical condition treatment. If the nightmares are associated with an underlying medical or mental health condition, treatment is aimed at the underlying problem. Stress or anxiety treatment. If stress or anxiety seems to be contributing to the nightmares, your doctor may suggest stress-reduction techniques, counselling or therapy. Medication. Medication is rarely used to treat nightmares. However, medications that reduce REM sleep or reduce awakenings during sleep may be recommended if you have severe sleep disturbance. Imagery rehearsal therapy. Often used with people who have nightmares as a result of PTSD, imagery rehearsal therapy involves changing the ending to your remembered nightmare while awake so that it's no longer threatening. You then rehearse the new ending in your mind. This approach may decrease the frequency of nightmares.
LIFESTYLE AND HOME REMEDIES-
If you're having nightmares, try some relaxation techniques before bedtime. Take a warm bath, meditate or practice deep breathing. A consistent bedtime routine is important. If your child is struggling with nightmares, be patient, calm and reassuring. Sometimes a little creativity helps, too. Offering comfort. After your child awakens from a nightmare, respond quickly and soothe your child at the bedside. This may prevent future nightmares. Talk about the dream. Ask your child to describe the nightmare. What happened? Who was in the dream? What made it scary? Then remind your child that nightmares aren't real and can't hurt you. Put stress in its place. If your child seems anxious or stressed, talk about what's bothering him or her. Practice some simple stress-relief activities, such as deep breathing. Rewrite the ending. As in imagery rehearsal therapy, help your child imagine a happy ending for the nightmare. Encourage your child to draw a picture of the nightmare, "talk" to the characters in the nightmare or write about the nightmare in a journal. Provide company. Your child might feel more secure if he or she sleeps with a favourite stuffed animal, blanket or other comfort object. Brighten up. Use a night light in your child's room. If your child wakes up during the night, the light might be reassuring. Open the doors. Leave your child's door open at night so that he or she won't feel alone. Leave your door open, too, in case your child needs comfort during the night.
