Independent of mental disorders, nightmares are often associated with sleep problems such as prolonged sleep latencies, poorer sleep quality, and daytime sleepiness.
Sleep deprivation.
Changes in your schedule that cause irregular sleeping and waking times or that interrupt or reduce the amount of sleep you get can increase your risk of having nightmares. Insomnia is associated with an increased risk of nightmares.
Nightmares can arise for a number of reasons—stress, anxiety, irregular sleep, medications, mental health disorders—but perhaps the most studied cause is post-traumatic stress disorder (PTSD).
According to a new study, sleeping too much could be the cause of your nightmares. Researchers from the University of Oxford surveyed 846 adults and found that those reporting more than nine hours of sleep a night were 45% more likely to have nightmares than those who slept for a shorter amount of time.
While it's common to have nightmares every once in a while, if you have them frequently and they interfere with your daily functioning, you may have nightmare disorder. Common themes of nightmares include threats to your: Survival. Physical well-being.
What do frequent nightmares actually mean? If you have a certain nightmare over and over again, your subconscious may be trying to tell you something important. “Nightmares are the brain working through emotions,” says Wallace.
Nightmares about falling were followed closely by dreams about being chased (more than 63 percent). Other distressing nightmares included death (roughly 55 percent), feeling lost (almost 54 percent), feeling trapped (52 percent), and being attacked (nearly 50 percent).
While other parasomnias (sleep-disrupting disorders) can also cause nightmares, when it comes to sleep apnea, it's the lack of oxygen that contributes to bad dreams.
Remembering your dreams doesn't necessarily have anything to do with how restful your sleep is, Dr. Harris says. Instead, recalling those dreams is a lot more likely to depend on a number of factors, from your current level of stress to the medication you're taking.
Sleep terrors differ from nightmares. The dreamer of a nightmare wakes up from the dream and may remember details, but a person who has a sleep terror episode remains asleep. Children usually don't remember anything about their sleep terrors in the morning.
"For many people, the adrenaline and excitement experienced upon realizing that they are dreaming is enough to wake them," Backe said. "However, if this is not the case and you are 'stuck' in a bad dream, doing something particularly jarring — for example, jumping off of a cliff in your dream should do the trick."
Most experts believe that lucid dreams are the rarest type of dreams. While dreaming, you are conscious that you are dreaming but you keep on dreaming. According to researchers, 55 percent of people experience these types of dreams at least one time in their life.
According to current diagnostic classifications, nightmares are defined as frightening or disturbing dreams that awaken the sleeper while bad dreams are defined as frightening or disturbing dreams that do not awaken the sleeper (Hasler & Germain, 2009; Nadorff et al., 2014).
Nightmares, dreams and other sleep disturbances are a common symptom of complex trauma with nightmares recognised as a principal feature of post-traumatic stress disorder (PTSD). The treatment of nightmares not only alleviates those symptoms but is shown to help reduce PTSD symptoms in general.
Can anxiety cause nightmares? “Yes, anxiety and stress can cause nightmares and anxiety dreams,” says Dr. Roberta Ballard, a clinical psychologist from Marietta, Georgia. “If you are under more stress than usual or there is a big change going on in your life, you might notice more themes of anxiety in your dreams.”
While people talk about “night terrors,” this is not, in fact, a diagnosable condition, according to the Diagnostic and Statistical Manual fifth edition (DSM-V). It contains elements of conditions known as nightmare disorder, REM sleep behavior disorder, and Non-Rapid Eye Movement (NREM) Sleep Arousal Disorder.
Stress, anxiety or depression
A particularly stressful day can lead to intrusive thoughts in the middle of the night — maybe they come in the form of a nightmare that jolts you up at 3 a.m. In more serious cases, some people even experience sleep paralysis. Anxiety can also make it difficult to sleep through the night.
Depression and other psychiatric disorders — Frequent and intense nightmares may occur in association with a wide range of psychiatric disorders, including depression, anxiety and panic disorders, schizophrenia, and borderline personality disorder [11].
For instance, feelings of powerlessness, lack of safety, trust and shame are common themes in recurrent nightmares." These loopy dejá vu dreams can be spurned as side effects of general anxiety for sure, and could be fleeting; or, they may be long-carried remnants of trauma experienced early in your life.
No. You may think you're rescuing your bedmate from misery, but rousing someone simply means he'll need several frustrating minutes (or longer) to calm down and get back to sleep. The truth is, nightmares are normal.
