If someone scares you while you're sleeping, you may experience a parasomnia, which is a type of sleep disorder characterised by behaviours or events that interrupt sleep. Parasomnias include sleepwalking, sleep terrors, and sleep paralysis. While the cause of night terrors is unknown, they are thought to occur when an individual's consciousness is trapped between deep sleep and wakefulness. Night terrors can be challenging to manage and may require medical attention if they occur frequently and impair your ability to obtain restful sleep.

Night terrors: A person might experience disruptive, frightening episodes while sleeping
Night terrors are sleep disturbances where a person may scream, shout, cry, or move around violently while still asleep. They are often accompanied by fear and panic symptoms, and the sleeper may even get out of bed. However, the person usually remains asleep during a night terror, and many people fall back asleep as soon as the episode ends. Night terrors are not usually a cause for medical concern and are unlikely to cause any permanent harm. They are more common in children, with an estimated 40% of children experiencing them, but adults can also suffer from them.
During a night terror, the brain is in a state between being partially asleep and partially awake, which can cause feelings of fear and panic. While the person experiencing the night terror may not remember the episode in the morning, it can be alarming for those who witness it, such as parents, caregivers, or sleeping partners. It can be challenging to comfort the person experiencing a night terror, and they may not wake up easily if someone tries to wake them. In fact, attempting to wake them may prolong the night terror episode.
To help someone experiencing a night terror, it is recommended to gently guide them back to bed if they have gotten up and to speak to them calmly. Holding their hand can also help shorten the episode. It is important to stay with the person until they fall back asleep to ensure their safety.
Night terrors are often linked to sleepwalking and may be caused by difficulty in maintaining slow-wave sleep, which is the deepest stage of sleep that occurs in the early part of the night. Certain underlying conditions, such as sleep apnea, restless leg syndrome, or mental health issues, can also contribute to night terrors. Managing these conditions and improving sleep habits and the sleep environment can help reduce the frequency of night terror episodes. While medication is not typically recommended, it may be considered in rare cases where the episodes are frequent and pose a risk of injury or significantly impact daily functioning.

Sleepwalking: Sleep disruption can cause people to walk around, unaware of their surroundings
Sleepwalking, or somnambulism, is a sleep disorder that causes people to move around and perform activities that are usually done while awake. It is characterised by a combination of sleep and wakefulness, occurring during the slow wave stage of sleep, when a person is in a state of low consciousness. While sleepwalking, individuals may walk around, sit up in bed, eat, clean, or even engage in hazardous activities like cooking or driving. Sleepwalking usually occurs within the first two to three hours of falling asleep and is common in children, with some adults experiencing it as well.
Sleepwalkers exhibit limited awareness of their physical surroundings and may not react to things in their field of vision, despite having their eyes open. They often demonstrate some ability to navigate their environment due to a combination of simple stumbling and habit. Sleepwalkers are typically disoriented when they awaken, feeling confused and not remembering how they got out of bed. This disorientation usually fades within minutes, but sleepwalkers often have little to no memory of the incident.
Sleepwalking is often associated with other sleep disorders or conditions, such as sleep apnea, restless leg syndrome (RLS), or sleep-disordered breathing (SDB). It can also be linked to psychological disorders in adults and behavioural problems in children. In some cases, sleepwalking can lead to injuries or disrupt the sleep of others in the household. However, it usually doesn't require direct treatment, and preventive measures can be taken to ensure safety.
To reduce the likelihood of sleepwalking episodes, relaxation and stress management techniques can be employed to lower stress levels, which may be a triggering factor. Treating underlying conditions that cause arousal from sleep, such as sleep apnea, can also help reduce sleepwalking episodes. While sleepwalking itself may not be harmful, it is important to take precautions to ensure the safety of the sleepwalker and those around them. This may include ensuring a safe environment, removing hazards, and seeking medical advice if sleepwalking is frequent or causing concern.
While it is not directly related to the act of scaring someone while they are sleeping, sleepwalking can be a result of sleep disruption or arousal from sleep. So, if someone is startled or scared while sleeping, it could potentially trigger a sleepwalking episode, especially if the person is already prone to sleepwalking. However, there are no specific mentions of scaring a sleepwalker as a direct cause of sleepwalking in the sources provided.

Sleep paralysis: Being scared while sleeping can result in an inability to move
Sleep paralysis is a frightening but harmless phenomenon that occurs when one is conscious but unable to move or speak while falling asleep or waking up. It is characterised by a complete state of full-body paralysis, with episodes lasting from a few seconds to several minutes. Sleep paralysis can be a one-time occurrence or recur multiple times, and it affects about 8% to 50% of people at some point in their lives.
During an episode, individuals may experience hallucinations, such as imagined sounds like humming, hissing, static, or buzzing. They may also hear voices, whispers, or roars, and sometimes see dark figures or feel an intruding presence in the room, often referred to as "sleep paralysis demons". These hallucinations can result in intense fear and panic, with physical sensations such as pressure on the chest, intense head pain, feelings of drowning or sinking, numbness, and electric tingles throughout the body.
The exact cause of sleep paralysis is not fully understood, but it has been linked to various factors. One theory suggests it results from a dysfunctional overlap of the REM (rapid-eye movement) sleep and waking stages. Sleep paralysis is more likely to occur during periods of high stress, sleep deprivation, or abnormal sleep cycles. It has also been associated with underlying conditions such as insomnia, post-traumatic stress disorder, and narcolepsy, and it may have a genetic component, running in families.
While there is no treatment to stop a sleep paralysis episode once it starts, certain measures can be taken to reduce the frequency of episodes. These include improving sleep hygiene, cognitive behavioural therapy, and, in some cases, medication typically used to treat depression at lower doses. If sleep paralysis is a concern, it is recommended to consult a healthcare provider, who can help identify underlying causes, provide treatments, or offer self-care advice to lower the risk of future episodes.

Risk factors: Certain factors, like family history, increase the likelihood of sleep disorders
Sleep disorders are conditions that affect sleep quality and duration, impacting overall health and quality of life. While there are over 80 different sleep disorders, insomnia is the most common. Other sleep disorders include sleep apnea, parasomnias, narcolepsy, and restless leg syndrome. Certain risk factors, such as family history, increase the likelihood of experiencing sleep disorders.
Family history appears to be a significant risk factor for insomnia. Studies have found that a large percentage of individuals with insomnia report a family history of sleep problems, with higher rates among those with early-onset insomnia. Genetic effects account for about one-third of the variance in insomnia complaints. Additionally, a genetic predisposition has been established for normal sleep and most other sleep disorders, except for rare cases like fatal familial insomnia.
Sleep apnea, a common sleep disorder, also has a genetic component. Risk factors for sleep apnea include obesity, gender (with a higher prevalence in men), menopause, and endocrine disorders. Family history is another critical risk factor for sleep apnea, highlighting the influence of genetics on sleep disorders.
Circadian rhythm sleep-wake disorders involve a misalignment between an individual's internal body clock and the external light-darkness cycle. This misalignment results in significant sleep problems and daytime sleepiness, causing distress and functional impairment. While shift work and jet lag are external factors contributing to this disorder, internal factors related to an individual's body clock can also play a role.
While family history is a risk factor, it's important to note that sleep disorders can also be influenced by other factors such as age, sex, education, work status, behavioural and environmental factors, and the presence of mental or medical disorders. Lifestyle choices and certain medications can also impact sleep quality. Seeking professional help is essential to managing sleep disorders and improving overall health and well-being.

Treatment: Healthcare providers offer strategies to manage sleep disorders and improve sleep hygiene
Sleep is essential for both physical and mental health, and improving sleep hygiene can be a great way to promote consistent, uninterrupted sleep. Sleep hygiene refers to both your sleep environment and behaviour. It involves forming good habits and routines that make it easier to sleep soundly and wake up feeling well-rested. Here are some strategies to improve sleep hygiene and manage sleep disorders:
- Set a strict sleep schedule: Try to go to bed and wake up at the same time every day. This helps to regulate your body's internal clock and promote a consistent sleep-wake cycle.
- Optimise your bedroom: Create a quiet, relaxing, and cool environment. Minimise noise, adjust the temperature to your comfort, and ensure your bed is comfortable and inviting.
- Follow a bedtime routine: Develop a calming routine before sleep. This could include activities such as reading, meditation, or listening to soothing music. Avoid stimulating activities and electronic devices at least 30 minutes before bedtime.
- Form healthy habits: Adopt habits that promote better sleep. Avoid large meals, alcohol, and caffeine close to bedtime. Maintain a healthy diet and exercise regularly during the day, but avoid strenuous activities too close to bedtime.
- Maintain a sleep diary: Keep a record of your sleep patterns and habits. This can help you identify any issues or triggers affecting your sleep. It can also be a useful tool to share with your healthcare provider to better understand and manage your sleep disorder.
- Seek professional help: If you have persistent or severe sleep problems, consult a healthcare provider. They can recommend appropriate treatments and provide guidance tailored to your specific needs. Sleep disorders may require additional interventions beyond sleep hygiene improvements.
Remember, while improving sleep hygiene can be beneficial, it may not resolve all sleep disorders. If you have ongoing sleep difficulties, it is important to seek professional advice and explore other treatment options.
