Spontaneous lucid dreaming frequency and waking insight. Dreaming , ; 24 2 : DOI: ScienceDaily, 12 August The whole ordeal sounds like a nightmare, but in reality, there's nothing to be scared of. During REM sleep, our brains have vivid dreams. In order to ensure you don't physically act out the events of a dream, your brain temporarily paralyzes your entire body. This loss of muscle control is known as atonia.
Sometimes though, the brain experiences a glitch and inadvertently wakes you up while your body is still experiencing paralysis. Waking up and not being able to move is scary on its own, but the dreams from REM can influence what you see or feel when you wake up, making the experience even scarier. Hypnic jerks, also known as sleep starts, are involuntary muscle movements that occur just as you're falling asleep. If you've ever been just about to slide into unconsciousness, but suddenly feel like you're falling and jump awake, that's a hypnic jerk.
The muscle movements, called myoclonus, can be strong enough to wake a person, or gentle enough to not disturb the sleep at all. People may experience other symptoms alongside hypnic jerks, such as rapid heartbeat, rapid breathing, and sweating. There's no consensus on exactly what causes hypnic jerks, but they are related to the changeover between the sleep and wake cycles.
As sleep paralysis sets in, the system that controls waking sometimes experiences a last burst of wakefulness before the system that controls sleep takes over completely. In other words, hypnic jerks are the last gasps of normal daytime motor control. Anxiety, caffeine, nicotine, stress, and sleep deprivation may make this more likely to occur.
In fact, many people seem to experience in dreams what they cannot currently have in real life. What are the factors that explain these shifts? Both Barrett and Aspy point to the role that experiencing highly stressful or traumatic events plays in the nature of our nighttime dreams. The shelter-at-home situation was another big life change beyond the virus threat. This means that the high exposure to a sense of anxiety, as well as the information overload about the pandemic through different kinds of media, are bound to influence what people dream at night.
She went on to explain:. A rebound of lost sleep means an even bigger rebound of lost dream time. People can sometimes experience lucid dreams. These are dreams in which the sleeper is aware that they are asleep and dreaming. Aspy is an expert on the science of lucid dreams. He has also extensively researched strategies that can help a person train to experience lucid dreams. Aspy also explained that lucid dreaming techniques could come in handy at this time. He suggested that they could help people have less anxious dreams and, therefore, better sleep.
Repeat to yourself what you want to dream about as you drift off to sleep. According to Aspy, learning to lucid dream might also be helpful for those who would like to gain more control over their nighttime experiences.
