Sleepwalking is a phenomenon that has interested humans for thousands of years and as a result of such attention people have created many myths surrounding the topic. I am very interested in sleepwalking and think it is important to separate facts vs. fiction surrounding sleepwalking. Sleepwalking is actually very common in children since about 30% of children will sleepwalk at least once. It is much less common in adults, only 4-5% of adults sleepwalk. Most people picture sleepwalkers with their hands extended in front of them like zombies. This is a myth since sleepwalkers often clumsily roam with their eyes open, with a very glassy stare, and some times perform routine tasks. They have no recollection of their actions and, if talking is present, it is usually random and incomprehensible slurs.
The most common myth is to never wake up a sleepwalker because they will attack you, the comedic video below provides an example of this. In reality, it is very safe to awaken sleepwalkers. They will usually be disoriented and confused but will not attack. However, there have been cases where sleepwalkers have performed complex tasks and even committed murder. There have been several cases of murder where the defendant pleads temporary insanity on the grounds he or she was sleepwalking and has no recollection of the crime.
Hopefully the facts can be set straight now and this will better help people's understanding of sleepwalking. Try watching the video and separate fact vs. myth in the clip from Step Brothers.
