Nightmares Or Night Terrors Whats The Difference

What Are Sleep Cycles? – Everything You Need To Know!

Nightmares are often confused with night terrors, but the two are different. Night terrors are common in children aged 3-8 years old. They occur during deep sleep, when the body is relaxed and we usually dont dream.

A child who experiences night terrors might scream, shout and thrash around in extreme panic, but theyre unaware of whats happening because theyre still asleep.

Its a bit like sleepwalking. The child might appear distressed but in the morning theyll have no recollection of what happened, says Forster.

Its best not to wake a child when theyre having a night terror, or they will wake up and feel fearful, Forster recommends. If theyve got up while having a night terror, just gently guide them back to their bed.

A nightmare is quite different, as the intense emotions will inevitably cause the child to wake up, usually in a state of distress and fear, he adds.

Night terrors most commonly occur when the sleeper is aroused shortly after falling asleep or. So, how many stages of sleep do you go through?

Some Studies Suggest That Dreams Stem From Our Imagination Rather Than From Our Perception

To some people, the sensory experiences you have collected in the day are a prominent factor for your dreams storyline. To others, the abstract thoughts stem more from your imagination rather than what you have seen on any given day.

One meta study, which compared other researchers work and then combined it with their own findings, shows that there is more evidence for imagination during dreaming than simple perception recall.

Although our dreams might be inspired by something we have seen in the day, the object or person doesnt necessarily represent itself. Instead, a more abstract connection is made through our imagination.

Stages Of Sleep: The Sleep Cycle

There are five stages of sleep during the sleep cycle. Scientists categorized the stages of sleep based on the characteristics of the brain and body during sleep. Stage 1,2,3, and 4, are categorized as non-REM sleep, and the fifth stage, is REM sleep. Generally, brainwave frequencies and amplitudes from an electroencephelogram are used to differentiate the different stages of sleep, along with other biologic rhythms including eye movements and muscle movements .

Nightmares What Are They And How Do You Treat Them

Nightmares that occur frequently are a parasomnia dream state event, in which visual sequences unfold that often depict imagery or situations that are particularly disturbing or frightening to the individual experiencing them, and may often come from fears in their own subconscious.

When is a nightmare a disorder? Nightmares are considered a sleeping disorder when they occur frequently enough that they disrupt sleep on a regular basis, and may cause the subject further fear of sleeping, which can lead to sleep deprivation and the formation of other sleeping disorders or medical or psychological conditions.

How Are Nightmares Different From Sleep Terrors

Sleep terrors, sometimes called night terrors, are another type of parasomnia in which a sleeper appears agitated and frightened during sleep. Nightmares and sleep terrors have several distinguishing characteristics:

  • Nightmares happen during REM sleep while sleep terrors happen during non-REM sleep.
  • Sleep terrors dont involve a full awakening instead, a person remains mostly asleep and difficult to awaken. If awakened, they likely will be disoriented. In contrast, when a person wakes up from a nightmare, they tend to be alert and aware of what was happening in their dream.
  • The following day, a person with nightmares usually has a clear memory of the dream. People with sleep terrors very rarely have any awareness of the episode.
  • Nightmares are more common in the second half of the night while sleep terrors happen more often in the first half.

What Can Interrupt Your Cycle

Interrupted sleep is the term used to describe sleep that is not continuous throughout the night. When this happens, your sleep cycle can be disrupted. An in-progress sleep stage may be cut short and a cycle may repeat before finishing.

There are a number of issues that can interrupt your sleep cycles. Depending on which one is at play, this may happen occasionally or on a chronic basis.

Some factors that are associated with interrupted sleep and, therefore, may affect your sleep stages include:

  • Older age: Sleep naturally becomes lighter and you are more easily awoken.
  • Nocturia: Frequently waking up with the need to urinate
  • Sleep disorders, including obstructive sleep apnea and restless leg syndrome
  • Pain: Difficulty falling or staying asleep due to acute or chronic pain conditions, like fibromyalgia
  • Mood disorders such as depression and bipolar disorder
  • Other health conditions, including Alzheimer’s disease, Parkinson’s disease, obesity, heart disease, and asthma
  • Lifestyle habits: Little/no exercise, cigarette smoking, excessive caffeine intake, excessive alcohol use

Any time you have trouble falling asleep or staying asleep at night, your sleep cycle will be affected.

How Do You Stop Nightmares

Sleep and Dreams: How do they work?

If you often struggle with nightmares and lose sleep because of this problem, you need to know how to manage this condition. Working with a doctor or therapist to diagnose any underlying mental or physical causes of nightmares, like sleep apnea or mental illness, is a crucial first step.

Once you have an understanding of the causes of your nightmares, you can develop an approach to managing or treating the problem. The best options include finding ways to reduce your stress, like getting a higher quality mattress to sleep better, taking an herbal supplement that eases you into sleep, working with your doctor on prescription treatments, or using devices to manage your sleep disorder.

According to the DSM-5, the best approach to treating nightmares starts with social support from friends and family, which can reduce stress. Consulting a mental health professional for treatment after a stressful event like the loss of a loved one or trauma can help to manage PTSD symptoms, anxiety, or depression associated with these significant personal changes.

Physical illnesses like sleep apnea can be addressed with regular exercise and a healthy diet. This helps you maintain a healthy weight, which, in turn, reduces breathing-related sleep disorders.

Experiencing nightmares more than once a week on a regular basis requires medical attention. Work with your general practitioner first. Then, work with specialists you may be referred to.

Physical Enactment Of Dreams

During REM sleep almost all the muscles of the body are totally relaxed so that activities in the dreams cannot be physically expressed. Occasionally however this relaxation is lost and the content of the dream is physically acted out. This is characteristic of the REM sleep behaviour disorder in which dreams often have a particularly aggressive content.

When Do We Dream

The Stages of the Sleep Cycle

Most dreams happen during the rapid eye movement portion of sleep. REM is the period of sleep when the brain is most active. A small portion of dreams happen outside of REM sleep , especially during slow-wave NREM sleep. However, the vivid dreams that we are most likely to remember upon waking usually occur during REM sleep .

Sleep phases come in cycles that repeat throughout the night. REM sleep occurs every 90 to 100 minutes, three to four times a night. As the night goes on, REM cycles get longer, and dreams become more vivid. Sleep scientists believe the most vivid dreams that we can remember happen during the last, longest REM cycle closest to waking up.

Most dreams only last for around five to 20 minutes, though they may seem like they are going on for much longer. Short dream times allow us to have multiple dreams per night, whether or not we remember them.

What You Should Do

The best thing to do if your child is having an episode of night terrors is to stay calm and wait until they calm down.

Don’t intervene or interact with them, unless they’re not safe. Night terrors can be frightening to witness, but they don’t harm your child.

You shouldn’t attempt to wake your child when they’re having an episode. They may not recognise you and may become more agitated if you try to comfort them.

Your child won’t remember the episode the next morning, but it may still help to have a general chat to find out if anything is worrying them and triggering the episodes.

It’ll also help if they have a relaxing bedtime routine.

Try not to discuss the episodes with your child in a way that worries them as this may increase their anxiety.

If the night terror episodes are frequent and occur at a specific time every night, you may find that waking your child breaks the cycle.

Wake your child 15 minutes before the anticipated time of the episode every night for 7 days.

This can disrupt their sleep pattern enough to stop the episodes without affecting sleep quality.

Dreams occur during all stages of sleep. Nightmares are common. They can be associated with poor sleep and diminished daytime performance. Frequent nightmares are not related to underlying psychopathology in most children and in some creative adults. However, recurrent nightmares are the most defining symptom of post-traumatic stress disorder and may be associated with other psychiatric illnesses. Night terrors are arousal disorders that occur most often in children and usually occur early in the sleep period. Patients with rapid-eye-movement behavior disorder often present with nocturnal injury resulting from the acting out of dreams. Dream disorders may respond to medication, but behavioral treatment approaches have shown excellent results, particularly in patients with post-traumatic stress disorder and recurrent nightmares.

When you have a full night of uninterrupted sleep, the stages progress as follows:

  • Sleep begins with NREM stage 1 sleep.
  • NREM stage 1 progresses into NREM stage 2.
  • NREM stage 2 is followed by NREM stage 3.
  • NREM stage 2 is then repeated.
  • Finally, you are in REM sleep.
  • Once REM sleep is over, the body usually returns to NREM stage 2 before beginning the cycle all over again.

    Individuals with other sleep disorders, including sleep apnea, nocturnal asthma, and restless leg syndrome, are more likely to experience night terrors. Sleepwalking and night terrors also appear to be linked. Both can be caused by improper arousal during deep sleep, leaving them somewhere in a state between wakefulness and sleep. Those who regularly experience night terrors may have difficulty sustaining deep sleep.

    Additional night terror triggers include:

    • Sleep deprivation
    • Noise or light
