Sleepwalking: When Your Dreams Become Actions

Sleepwalking is a medical condition. It is also known by other names such as somnambulism and parasomnia. People who suffer from that medical condition get up while they are sleeping and can complete various actions varying from simple to complex. It is commonly believed that it is characterized by only walking while asleep, but in reality there may be other actions involved. A sleepwalker can perform complex activities while he is in this particular state. Sometimes the individual may simply sit up suddenly. He can even look around with a confused expression. In other cases, a person may just jump out of bed and run away from a threat that he is dreaming at the same time. Although it may scare some people, this condition is not serious. The only serious and harmful outcome which may arise is from an injury while the sleepwalker performs a certain action. Sleepwalking is not linked to any long-term complications.

In the past, sleepwalking was shrouded in mystery since there was no serious investigation into what causes it and if it was a medical condition at all. The first serious studies of sleepwalking were conducted in the 19th century by German parapsychologist and chemist Baron Karl Ludwig von Reichenbach. He formulated an extensive theory on that topic. His work put in place the foundation of the attempt to understand this condition.



At first, a person who suffers from somnambulism was considered as a dreamer who physically participates in his or her dream. With more observant and elaborate research, that notion changed. With the invention of electroencephalogram and others, more accurate studies appeared.

Sigmund Freud also analyzed and provided theories on that medical condition. According to him, sleepwalking and the fulfillment of sexual desires have some connection. Another of his suggestions was that a person’s sleepwalking is triggered by the desire to sleep in the same area where he slept as a child. Later on, he was preoccupied with the task to elaborately analyze dreams, their subconscious origins and the dreamer’s consciousness. Unconscious impulses during the sleep may be expressed with action during that state.

Sometimes, waking up a sleepwalker requires tremendous effort. Usually, when you succeed in waking them up, they feel flabbergasted because there is no memory of what they have done. In some cases, people can remember only particular moments of their actions. It is uncommon for a patient to remember what he has done during his unconscious state. In other cases, the sleepwalker may unconsciously attack the person who is trying to wake him up. Aggressive behavior in such situations is more typical for males. Sometimes, sleepwalking ends suddenly without any reason. The individual could get confused why he is in a particular place undertaking a certain action. Moreover, he does not have a clue how he ended up there. In other cases, the sleepwalkers can return back to bed and resume their normal night sleep without knowing that they were out of bed on a night journey.

Sleepwalking can occur with different frequency depending on the individual. It can be repeated several nights in a row. The only threat that should be considered as serious is that the individual may hurt himself or another person, including bed partners or people who live in the same house or even strangers on the street.

However, according to science, sleepwalking is fairly normal for children. It is seen as part of their early sleep pattern. They may go to their parents’ bedroom but can go to more dangerous journeys like going outside the house or staying extremely close to an open window. This can be really life-threatening. An older child can be more noisy and active while sleepwalking. Usually, he speaks while sleepwalking and have nightmares.

  • When Does Sleepwalking Occur?

Sleep is subdivided into four stages. They are known as non-rapid eye movement stage or non-REM. There is another stage which is called REM after the rapid eye movement that occurs during that phase. The REM stage allows a person to dream. Stage three of the sleep cycle is linked with the secretion of important hormones that are in charge of the individual’s growth and metabolism.

Each of the four stages has fixed duration between 90 and 100 minutes and the sleep cycle is repeated several times throughout the night. The average repetition of those stages is about four or five times per night, although it depends on the individual and his night routine. Sleepwalking occurs in stage three or four from the non-REM sleep. It can also appear in REM sleep near dawn. During stages 3 and 4, the person sleeps deeply. Naps are relatively short, thus the cycle cannot reach those stages where sleepwalking occurs. This is why it is unusual sleepwalking to occur during naps.
