Nightmares can be triggered by many factors, including: Stress or anxiety. 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.
According to clinician Jacky Casumbal, “Dreams are our brain's way of organizing events of the day, memories, and images into vivid, symbolic, and nonsensical storylines.” Nightmares in particular are “dreams that are often connected to unresolved anxiety and trauma that our brain has not fully worked through.”
Common causes include stress, negative life events, the experience of trauma as in posttraumatic stress disorder (PTSD), depression, other psychiatric disorders, and medication side effects.
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).
However, the part of the limbic system that's most active during sleep is the amygdala, which is most commonly associated with fear, aggression, and unpleasant emotions. The amygdala is why we experience nightmares.
Nightmares are associated with disturbed sleep, low well-being and affect daytime mood and behavior. Nightmare disorder is a very common comorbidity in nearly all psychiatric conditions.
Simply put, dreams that feel real occur when our brain activity is heightened during the REM (Rapid Eye Movement) part of our sleep cycle. During this stage of sleep, increased blood flow to the visual cortex in the back of your brain increases activity, giving us more vivid and realistic-seeming dreams than normal.
In REM sleep, our brain activity is near waking levels, but our body remains "asleep" or paralyzed so we don't act out our dreams while lying in bed. Since our brain is so active during this stage, it can sometimes scare us into waking up, essentially. As Girardin Jean-Louis, Ph.
However, it's important not to wake them up and allow them to work through the episode. They're more likely to forget the dream if they can sleep through it. Waking them up in the middle of a nightmare can be jarring, making it difficult for them to forget the imagery or get back to sleep.
If you can realize you're in a nightmare, the simplest way to stop it is to make yourself wake up, Arthuro said. But some evidence suggests that it's possible to stay in the nightmare but eliminate your fear by knowing you aren't in physical danger, according to Arthuro.
Upon waking up from a nightmare, it's normal to be acutely aware of what happened in the dream, and many people find themselves feeling upset or anxious. Physical symptoms like heart rate changes or sweating may be detected after waking up as well.
Night terrors and nightmares are different and happen at different stages of sleep. During a night terror you may talk and move about but are asleep. It's rare to remember having a night terror. Nightmares are bad dreams you wake up from and can remember.
Movement After a Nightmare
Movement can be helpful when waking up from a nightmare. Experts state that getting out of bed is beneficial if you cannot fall asleep within 20 minutes of waking up. It is recommended that going to another room can help refocus the mind, making it easier to fall asleep upon returning to bed.
"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."
The average dream length of a nightmare can be 10-20 minutes while bouts of night terrors can be up to 45 minutes in length.
Get up and do something.
Try to think about other stuff until you feel ready to go back to bed. You could also read a book or listen to music in bed to distract your mind with something else until you get sleepy again. Whatever takes your mind off the nightmare is great!
The sensations you feel while sleeping and the emotions you experience before bed may cause you to wake up crying. If you wake up crying from a bad dream, that is your body's response to the weight of the suppressed emotion.
Although some theorists have suggested that pain sensations cannot be part of the dreaming world, research has shown that pain sensations occur in about 1% of the dreams in healthy persons and in about 30% of patients with acute, severe pain.
In particular, nightmares can be an indicator of mental health problems, such as anxiety, post-traumatic stress disorder and depression.
Anxiety, Medication, and Personality May All Affect Dreams and Dream Recall. Remembering your dreams doesn't necessarily have anything to do with how restful your sleep is, Dr. Harris says.
