NIGHTMARE, CAUSES AND HELP NEEDED

Teeth falling out? Lost in the wilderness alone? Being chased but can’t scream? Most of us can remember at least one such dream for its vividness, resulting visceral fear and lingering discomfort.
The mind’s reel of midnight movies never ceases to amaze, and many of these dreams can be off-putting if not downright disturbing. From feeling all too real to playing on our deepest fears, bad dreams can also make it harder to get back to sleep and lead to bedtime anxiety for children as well as adults.
In the realm of dreams and nightmares, there remains more mystery than fact. It’s an area of neuroscience and psychology that’s hard to study, since each of us experiences a unique dream world that’s inherently subjective and hard to document with reliability.
While a few hypotheses exist, little is confirmed about why we dream, what causes specific dreams, or how it all works. However, there are some interesting theories on nightmares and recent research that offers insight and potential ways to minimize their occurrence and impact. Read on to see what might influence dreams and current opinions on how to cope with the bad ones.
What Is a Nightmare?
Nightmares are defined as dreams that bring out strong feelings of fear, terror, distress or anxiety. They feel more vivid or intense than a bad dream, and nightmares are often differentiated from dreams when they cause the sleeper to actually wake up and experience intense feelings upon waking. People who awake during a nightmare are likely to remember the details of it.

While you are snoozing, your brain is pretty busy during certain times of the night.
During Rapid Eye Movement sleep, brain waves exhibit activity fairly similar to waking, and your brain is consuming as much if not more energy than when you’re awake. Your eyes move rapidly (hence the name), but your muscles are in a state of paralysis. This temporary paralysis is a good thing, because during REM sleep your brain is still firing off commands in the motor cortex as you move around your dream world.
Nightmares typically occur during the REM phases of rest, showing up in the later half of your sleep. Little is known about why we dream in general, but popular theories range from managing subconscious thoughts, to sorting out memories and learned information, to purely random chemical signals. There also isn’t much information on exactly why dreams sometimes turn out to be nightmares, but it’s believed that some daytime factors can play an influential role.
Both children and adults experience nightmares and bad dreams, even though they are primarily associated with childhood. It’s estimated that 10-50% of three to six year olds experience nightmares that affect their sleep, with over 80% of seven to nine year olds occasionally experiencing bad dreams.

CAUSES:-

Anxiety and Stress

Stress and anxiety can come in many forms, from temporary everyday things like moving to a new place, changing roles at school or work, or failing at a task, to more major things like divorce, losing a family member, trauma, or anxiety disorders. Being stressed and feeling anxiety is associated with poor sleep in general, and both may also trigger a night

Media

The idea that scary movies, thrilling or suspenseful shows or even fear-inducing news broadcasts cause bad dreams is often expressed anecdotally. While difficult to study, many of us can recall a time where visual imagery and situations from media popped up in dream content. Scary movies can also cause stress and anxiety for some people (setting the stage for distressing dreams).

Eating Before Bed
Snacking too close to bed can cause indigestion, and it may also influence your metabolism and dreams. One study linked junk food with nightmares, while another found that a spicy meal close to bed disturbs sleep

Sometimes, nightmares can become more than just occasional disruptions, becoming a significant source of sleep anxiety. Nightmare disorder is a clinically recognized sleep disorder, classified by frequent and persistent nightmares that regularly disrupt sleep, cause bedtime anxiety and affect daytime behavior. They can also be a symptom of PTSD, which can have a dramatic effect on quality of life.
If you feel like nightmares are making it difficult to get a good night’s sleep often or feel anxiety around falling asleep due to bad dreams, it is worthwhile to discuss it with your doctor and/or a psychologist. They can assess if there are underlying conditions to resolve and prescribe the right treatments and medications when applicable.
Most importantly, don’t feel embarrassed to bring the issue up — nightmares aren’t childish. They can have a significant impact on your waking life, and social support along with healthy lifestyle habits can play an important role in minimizing their impact.
