Imagine Waking Up and Being Accused of Murder
In 2003, Kenneth Parks, a man from Canada, drove 23 kilometers while asleep to his mother-in-law's house. He stabbed her to death and injured his father-in-law. Parks remembered nothing. The court acquitted him because he was found not guilty on the grounds of sleepwalking—a decision that shocked the medical and legal world. How could someone commit brutal violence without awareness? This is the starting point of a mystery that challenges our definitions of responsibility and reality.
Basic Facts: What Is Sleepwalking?
Sleepwalking, or somnambulism, is a sleep disorder classified in the parasomnia family. It occurs during the slow-wave sleep phase, the deep sleep stage without REM. In this state, some parts of the brain show signs of being awake, while other parts are still in deep sleep. This phenomenon is called 'state dissociation disorder'—a condition where consciousness is split between two realities. The activities performed can range from simple actions like sitting on the bed, walking to the bathroom, or eating, to dangerous ones like driving, cooking, or committing violence. The eyes of a sleepwalker are usually open but appear dull and vacant, without expression. These incidents can last from 30 seconds to several minutes, and most sleepwalkers have no direct memory of the event.
Extreme Cases: Driving, Cooking, Killing
Among the most famous sleepwalking cases are those involving complex activities. For example, a man in Britain was reported to have driven a car for 10 miles while asleep without an accident. More confusingly, some people have cooked full meals—chopping vegetables, frying eggs, and serving them—without remembering it the next day. The most dramatic case is like Kenneth Parks: murder in sleep. Another case involved a woman who drove to her mother's house and stabbed her, but was later acquitted due to evidence of sleepwalking. Scientists are still unclear how the brain can coordinate complex motor movements like driving without cognitive awareness. Hypotheses suggest that the part of the brain controlling automatic movement, such as the basal ganglia, is active, while the prefrontal cortex responsible for decision-making and self-awareness is not functioning.
Hypotheses and Controversies: Reality or Excuse?
Although the medical community recognizes sleepwalking as a real phenomenon, there is strong skepticism, especially in violent cases. Some experts argue that sleepwalking may be used as an excuse to avoid punishment. Dr. Michel Cramer Bornemann, a sleep expert, stated that complex activities like driving require high visual and motor coordination, and it is hard to believe they occur without at least some awareness. However, studies using EEG show that the brain of a sleepwalker is in a 'split state'—delta waves (deep sleep) and alpha waves (awake) exist simultaneously in different parts of the brain. This explains why someone can open their eyes, move, but not respond to the environment in a normal way. Another controversy is about memory: although most people don't remember, there are rare reports of partial memory, raising questions about the actual level of awareness.
Triggers and Treatment: An Ongoing Mystery
Triggers for sleepwalking include lack of sleep, stress, fever, alcohol, and certain medications. It is more common in children and usually disappears with age, but in adults, it can become chronic and dangerous. The main treatment is managing the triggers—such as ensuring adequate sleep and avoiding alcohol. In extreme cases, drugs like benzodiazepines or antidepressants may be prescribed. However, there is no specific cure. The unanswered mystery: why do some people perform dangerous activities without injury? For example, a man was reported to have walked on the roof of his house while asleep without falling. Does the brain of a sleepwalker have an internal safety system that is not understood?
Scientific Boundaries: What We Don't Know
Science is still struggling with basic questions: why does the brain enter this dissociation state? One theory suggests it is a defect in the 'switch' mechanism between sleep and wakefulness—like a system that doesn't function properly where one part of the brain 'wakes up' while the other 'falls asleep'. Another theory links it to genetics, as it often occurs in families. However, no model can accurately predict who will sleepwalk or perform complex actions. Even deeper, this phenomenon challenges the concept of consciousness itself: if someone can perform motivated actions like killing without awareness, what is our definition of intent and moral responsibility?
Conclusion: An Enduring Mystery
Sleepwalking is an anomaly that crosses the boundaries of biology, psychology, and law. From driving a car to killing, it shows that the boundary between conscious and unconscious is more blurred than we think. Although science has uncovered many facts—such as its relationship with slow-wave sleep and the dissociation state—the final answer remains out of reach. Each new case adds another layer of mystery, leaving us with endless questions. One thing is certain: sleepwalking is not just a sleep disorder, but a clue to the unknown secrets of human consciousness.
