What are nightmare dreams about?

You can gain insight from thinking about any dream, no matter how strange. Only you, as the dreamer, have final say on what your dream may or may not mean. Each dream is unique.

The DreamWell dictionary provides information on how each dream symbol appears in dreams in general. Finding how experience nightmares in dreams can be a key to understanding its meaning.

Our emotions in dreams can help us understand its meaning. Pay attention to how you felt in the dream. Pay attention to how you feel about nightmares in dreams. See how you feel about nightmares now, in your waking life.

A nightmare can be a big flashing sign that warns, “Something’s wrong!” A situation has gone on too long. Stress levels are too high. Something about you or your life needs to change, pronto.

Think of a nightmare as shock therapy, an attempt to break a pattern or get your attention after gentler methods fail. Dreams usually try to get through to you in what you might call a normal speaking voice, and they crank up the volume if you don’t get the message. It’s like shock therapy, a last resort.

Dreams tend to focus on unprocessed emotions. You haven’t worked them through your system, so your dreams take up the slack. If you want to lessen the odds of having nightmares, process your emotions consciously. Don’t give your nightmares fuel for the fire.

Fear is the number-one emotion behind nightmares, and some fears are more obvious than others. For example, if you fear spiders and dream about them crawling all over you, the dream could be a way of amplifying or confronting the fear. And if you successfully confront a fear in a dream, you’re likely to reroute your brain’s neural pathways away from that fear, creating a lasting change. Or if you fear heights you might find yourself dreaming about being stuck on top of a skyscraper, and your choice is to overcome the fear or succumb to it.

Don’t worry. If you fail the first time, you’ll be put back in the scenario again, and again, and again—as many times as necessary till you get it right.

It’s very important to understand that the imagery in your nightmares is not to be taken literally. It’s symbolism. It’s telling a story. For example, see: Incest. Incest, the ultimate taboo, is symbolism in a dream. If you take it literally you’ll end up judging yourself for it and completely miss the point.

Nightmares come in three general varieties.

1. Trauma. You can also call them “shock to the system” nightmares stemming from sudden, dramatic, and traumatic events. You find out your spouse is cheating. A layoff is coming at work. Someone close to you dies, and the death provokes a nightmare. Trauma nightmares tend to be meaningful but often there isn’t much that can be learned from them or changed as a result. These nightmares reflect the events that spark them—events that are probably beyond your control—and act as a release valve. Your best bet to avoid this sort of nightmare is to consciously process your thoughts and emotions after a shocking or traumatic event. If you have been through trauma, for example because of fighting in combat or abusive parents, then you will dream about it, and it will hurt. It might seem cruel to relive traumas in dreams, but if you believe what Carl Jung said, all dreams—nightmares included—are for your benefit. In a moment we’ll discuss why.

2. Abuse. Chronic stress. Some sort of addiction or compulsion. Self-abuse. A prolonged situation that’s harming you, or something untenable. Abuse nightmares are most likely to be potentially beneficial, because they’re often brought on by something that can be changed or addressed. For example, you are aware that a work or home situation is stressful, but it takes a nightmare for you to realize how much of a toll it’s taking. You can change the situation or take steps to alleviate stress. Or you know you have been ignoring the warning signs that your health is deteriorating, but it takes a nightmare about dying to spur you to action.

3. Illness. Fever dreams and “something I ate” nightmares are brought on by indigestion and certain medications. Spicy foods and heavy dairy products are known to produce nightmares, especially if eaten just before bed. Also, SSRI and other psychoactive drugs are known to cause them. Withdrawal from the drug Cymbalta even has the term “Cymbalta nightmares” associated with it, noted for extreme gore and violence. Often, there isn’t a deeply personal message or meaning. The body reacts to something inside it, and dreams translate it into scary imagery. Or in the case of withdrawal, the body reacts to something taken from it.

Nightmares help you by putting psychological distance between you and the event, trauma, or situation. Once the dream is finished it is “in the past,” behind you. It creates a mental cushion.

A nightmare provides emotional release. Think of it as a safety valve for pressure. If you don’t dream about the trauma and let the emotions out, the pressure building inside you might erupt.

Nightmares give you ways of viewing situations in your life as stories and working with the imagery to find resolution. Dreams function at a neurological level to reroute neural pathways, called “neuroplasticity,” a process of reorganizing and rerouting the brain. See: Letters

For example, let’s say you were a soldier and are haunted by the blood on your hands. No matter how you justify it, it’s just wrong, and your conscience won’t let up. You can’t change what happened, but dreaming can give you some distance from it. It can give insights. It can help you reprocess the experiences in a way that heals the trauma.

You can work with the imagery consciously as a sort of therapy. It’s amazing what apologizing to a dream character and resolving to learn from your mistakes can do. And you don’t have to be dreaming to do it. A heartfelt daydream can do the trick, or try dream rescripting and active imagination technique.

In some nightmares, what makes them so frightening is obvious—the serial killer pursuing you; the tidal wave enveloping you; the evil presence haunting you—but sometimes your reactions stand out. When you react powerfully to imagery in a dream, it’s because you subconsciously know what it symbolizes.

For example, you dream about going into the basement of an abandoned home and seeing a young child. It floats in the air and its head spins around like in the movie The Exorcist. For some people, such imagery might be disconcerting or frightening but not terrifying. They wouldn’t necessarily describe it as nightmarish because what it represents to them is not at that level. Hell, they might even think it’s funny.

But for other people, such a scene is no laughing matter. It might induce panic and cause them to wake up screaming. Why? Because they recognize something about themselves in that child, such as repressed memories from childhood causing current emotional problems. To them the child symbolizes something they have been avoiding at all costs, while to someone who reacts more mildly the child might symbolize that he or she acted childishly the previous day—not exactly nightmare material.

Which brings up a point that everything in a nightmare is a projection of something about you and your life, except on occasion when it’s a direct representation of a nightmarish experience.

Nightmares are easy to confuse with sleep paralysis. See: Sleep paralysis

Chronic nightmares can be caused by airflow obstruction while sleeping, such as from snoring or sleep apnea. It causes your body to send panic signals to the brain—Help, I need to breathe!—which the brain then translates to scary, even life-threatening imagery and scenarios. Oftentimes, the dreams have themes or imagery related to lack of air, or to ventilation. For example, a man dreams recurrently about being stuck upside down in a chimney. He has sleep apnea, and the chimney symbolizes his airway. To help determine if your nightmares have a physical cause, you can ask your sleeping partner to monitor your sleep, or use a voice-activated recorder to record the sounds you make while asleep. A popular phone app, Sleep Talk Recorder, turns your phone into a voice-activated recorder.

And finally, chronic nightmares can be caused by REM deprivation. It’s a serious problem in this age of twenty-four-hour schedules, night work and the constant distraction caused by electronics, especially phones. Search online and check whether the symptoms of REM deprivation, which include drastic mood swings and inability to focus, match what you are experiencing. A hallmark of REM deprivation is dreaming about being fatigued or sleepy.
