Dream experts believe the answer is yes, nightmares do serve a purpose. And though there's no single, united theory as to what that purpose might be, research is increasingly showing that nightmares could help people better navigate their waking lives.
Indeed, studies suggest that nightmares are often linked to unmet psychological needs and/or frustration with life experiences. Yet those links aren't always easy to make—except in cases of trauma (discussed below), our nightmares tend to reflect our troubles through metaphor rather than literal representation.
In many cases, they may help the dreamer ameliorate some of their daytime anxieties. Research has found that nightmares can help some people learn to better manage stress.
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).
No, we should never ignore bad dreams. We give priority in our dreams to things that seem to be a threat to our wellbeing, or even potentially our lives. For instance, children who grow up in violent homes are likely to have quite severe nightmares.
In a way, chronic nightmares can be a warning about your physical or mental health. If chronic nightmares are disturbing your sleep, it's worth bringing it up to a doctor or therapist. They'll be able to help you create a plan for more peaceful sleep.
1. Being chased. Being chased is one of the most common nightmares. If you dream that you're being chased by something, whether it's an 8-foot-tall rabbit or a shrouded figure, then it's an indicator that you're running away from something or someone in real life.
While nightmares are associated with certain mental health conditions, such as PTSD, anxiety and depression, nightmares aren't considered a psychiatric illness. They're a type of parasomnias, which are behavioral sleep abnormalities.
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) sleep.
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.
The overall pattern seen in the analyses reflect the significant relationship between nightmares and stress, while the finding that nightmares were positively associated with coping bolsters the supposition that nightmares may help to alleviate stress.
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).
"If you wake from a nightmare and have difficulty falling back asleep, get out of bed, do something soothing like a few yoga poses or find a place to sit, close your eyes, and try a breathing technique or relaxation exercise."
Nightmares are highly dysphoric dreams involving intense negative emotions which primarily present during late-night rapid eye movement (REM) sleep [1]. About one in 20 of the general population experiences nightmares every week [2].
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.
At this time there is little scientific evidence suggesting that dreams can predict the future. Some research suggests that certain types of dreams may help predict the onset of illness or mental decline in the dream, however.
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.
A night terror is a sleep disruption that seems similar to a nightmare, but is far more dramatic. Though night terrors can be alarming for parents who witness them, they're not usually cause for concern or a sign of a deeper medical issue.
Based on this analogy, Freud claims that nightmares are dreams with a sexual content whose libido is transformed into anxiety. The content is generally exempt from any form of distortion and represents the unveiled realization of a repressed desire that has shown itself to be stronger than censorship.
Repressed memories can come back to you in various ways, including having a trigger, nightmares, flashbacks, body memories and somatic/conversion symptoms. This can lead to feelings of denial, shame, guilt, anger, hurt, sadness, numbness and so forth.
