Nightmares may be linked to muscle spasms. Sleep myoclonus, or hypnic jerks, are sudden, involuntary muscle twitches that occur as a person falls asleep or during sleep. These spasms are usually harmless, but they can be painful and may cause minor bumps or cramps. While the exact causes of hypnic jerks are unknown, they are thought to be linked to stress, fatigue, caffeine consumption, and sleep position. Nightmares can also cause physical reactions in the body, such as contorting the spine and causing back spasms and pain. Additionally, extremely stressful dreams can lead to an increased release of hormones, triggering a fight-or-flight response and elevating blood pressure, which may contribute to muscle spasms.

What You'll Learn
Nightmares can be a response to physical pain
While there is limited research on the direct relationship between nightmares and muscle spasms, there is some evidence to suggest that nightmares can be a response to physical pain. Nightmares are frightening or disturbing dreams that cause nocturnal awakening, while bad dreams are disturbing but do not cause the sleeper to wake up.
Some people have reported experiencing back spasms during nightmares. One theory suggests that physical pain or muscle tension can trigger nightmares. For example, sleeping in a certain position may cause pressure on the lower back and contortion of the spine, leading to muscle spasms. As a result, the brain may create nightmares as a response to these physical sensations, shocking the sleeper awake.
Additionally, stress and anxiety can also contribute to both nightmares and muscle spasms. Experiencing an extremely stressful event in a dream can cause the brain to release a surge of hormones, triggering a fight-or-flight response in the body. This response can lead to increased blood pressure and muscle spasms, particularly in the lower back.
Furthermore, there is research that explores the link between nightmares, vitamin D deficiency, and musculoskeletal pain. One study investigated the associations between types of dreams, psychological symptoms, vitamin D levels, and calcium intake in individuals with musculoskeletal pain. The findings suggested that vitamin D deficiency increases the risk of chronic musculoskeletal pain, which is associated with anxiety and depression. Thus, addressing vitamin D deficiency and increasing calcium intake may help prevent nightmares and reduce physical pain.
While the exact mechanisms are not fully understood, it is clear that there is a complex interplay between nightmares and physical pain, including muscle spasms. Further research is needed to fully elucidate the underlying causes and relationships between these experiences.

Stress in dreams can cause muscle spasms
Muscle spasms are involuntary contractions of the muscle that can be painful and disruptive. They can occur in one or multiple muscles and can range from mild twitches to severe, full-body contractions. While muscle spasms can affect anyone at any time, they may be more common or severe in people with certain medical conditions, such as Huntington's disease or Parkinson's disease.
In the context of nightmares, muscle spasms can be understood as a physical response to the stress and anxiety induced by the dream. The intense emotions and physical sensations experienced during a nightmare can trigger the body's stress response, leading to muscle contractions and spasms. This can be particularly pronounced if the nightmare involves physical danger or threat, as the body prepares itself for a potential fight-or-flight situation.
Additionally, the stress and anxiety that often accompany nightmares can make it difficult to relax and prepare for sleep. This heightened state of arousal can further contribute to muscle tension and spasms. It is also possible that the physical sensation of muscle spasms influences the content of nightmares, creating a feedback loop that intensifies both the physical and emotional distress.
To manage muscle spasms caused by stressful dreams, it may be helpful to address the underlying stress and anxiety. This can include practising relaxation techniques before bed, such as deep breathing or meditation, and establishing a calming bedtime routine. Additionally, seeking professional help for managing stress and anxiety can be beneficial in reducing the frequency and intensity of stressful dreams and associated muscle spasms.

Sleep myoclonus and hypnic jerks
Sleep Myoclonus
Sleep myoclonus refers to involuntary, non-rhythmic muscle twitching that occurs either as a person falls asleep or during sleep. It can occur on its own or as a symptom of a sleep disorder or other medical condition. For example, it has been linked to nocturnal leg spasms, Restless Legs Syndrome (RLS), and pediatric periodic limb movement disorder (PLMD), which causes brief muscle spasms in the legs or arms during sleep. Sleep myoclonus has also been associated with Huntington's disease and Parkinson's disease, and it frequently occurs in people with epilepsy. Treatment options for sleep myoclonus include addressing any underlying conditions and, in some cases, medication such as antiseizure or anticonvulsant drugs.
Hypnic Jerks
Hypnic jerks, also known as sleep starts, are sudden, involuntary muscle contractions that occur as a person is falling asleep. They often feel like a jolt or a falling sensation. While the exact cause is unknown, researchers suspect that it may be due to a misfire between nerves in the reticular brainstem. Hypnic jerks are common, with 60-70% of individuals experiencing them at some point, and they are usually harmless. Overtiredness, uncomfortable sleeping positions, stimulants such as caffeine or nicotine, and high levels of stress and anxiety are all possible contributing factors to hypnic jerks.
While nightmares themselves may not directly cause muscle spasms, the stress induced by a nightmare could trigger a fight-or-flight response, leading to increased muscle tension and spasms. Additionally, the physical sensation of muscle spasms during sleep can influence the content of dreams, creating a feedback loop between physical sensations and dream content.

Nightmares and physical pain can be a two-way street
When you experience a stressful event in a dream, your brain releases stress hormones, sending your body into a “fight or flight” response. This increases your blood supply, leading to muscle spasms, particularly in the lower back. These muscle spasms can be painful and may cause lingering discomfort for a day or two. They can range from mild twitches to severe contractions that feel like your entire muscle has stiffened into a tight ball. While muscle spasms are usually not serious, they can be a symptom of an underlying condition, such as sleep myoclonus, a condition characterised by involuntary muscle twitching during sleep. In some cases, sleep myoclonus is linked to other sleep disorders, such as nocturnal leg spasms and restless leg syndrome.
On the other hand, physical pain can also be the cause of nightmares. If you experience muscle tension or pain while sleeping, your brain may create nightmares to explain the discomfort. For example, you might dream about being attacked by a bear and then wake up with a back spasm. Additionally, certain sleep positions can cause lower back and hip pain, which may influence the content of your dreams.
To manage muscle spasms caused by nightmares or other factors, muscle relaxants, stretching, and massage can be helpful. However, it is important to consult a healthcare professional if muscle spasms are severe or frequent, as they may recommend treatments to address the underlying cause.

Nightmares causing muscle spasms in children
Nightmares are vivid dreams that evoke feelings of fear, terror, and anxiety. They are common in children, with roughly half of children between the ages of 3 and 6 reporting frequent nightmares. While nightmares typically occur during rapid eye movement (REM) sleep, they can cause sleep disturbances and impact a child's ability to fall back asleep.
Parasomnias refer to sleep disorders characterised by behaviours or events that disrupt sleep, such as sleepwalking, sleep terrors, and sleep paralysis. Nightmare disorder is a type of parasomnia, and children who experience parasomnias may wake up feeling scared, confused, or anxious. While nightmares themselves may not directly cause muscle spasms, the stress and anxiety associated with them could trigger involuntary muscle twitching or spasms known as sleep myoclonus.
Sleep myoclonus refers to involuntary muscle twitches or spasms that occur when falling asleep or during sleep. These spasms can be mild or strong enough to jolt a person awake. While sleep myoclonus is typically harmless, frequent and intense spasms can disrupt sleep and indicate an underlying condition. Pediatric periodic limb movement disorder (PLMD) is a type of sleep myoclonus that causes brief muscle spasms in the arms or legs during sleep in children.
In addition to parasomnias, children may experience hypnic jerks or sleep starts, which are sudden involuntary muscle twitches that occur as one falls asleep. These jerks are usually harmless and may be more frequent during periods of stress or fatigue. However, strong hypnic jerks can lead to minor bumps or muscle spasms. While nightmares may not be the direct cause of muscle spasms, the anxiety and stress associated with them could contribute to the occurrence of hypnic jerks or sleep myoclonus, indirectly linking nightmares and muscle spasms in children.
If a child experiences frequent nightmares and muscle spasms that interfere with their sleep or daily functioning, it is recommended to seek advice from a healthcare professional. Treatment options for muscle spasms associated with nightmares may include counselling, relaxation techniques, and, in some cases, medication.
