We all have stayed up to late studying and on weekends at college, so some people may have experienced a sleepwalker. A main cause to the sleep walking is lack of sleep in previous days/nights before, which is a main reason why its so important to get a healthy amount of sleep. I have only had one experience with sleepwalking before in my life and it was something that kind of freaked me out as a child because I never really understood it.
I am very close with two of my cousins, they are basically like my brothers. Every summer they come out to Minnesota from Boston for a month, July, and they stay with my family. This is something that has been a tradition since we were born. When he was younger my cousin Kevin slept walk all of the time. It was something that we were all very concerned about because he would not only just get up and move around but he would rummage through cab nits and get into different foods. It was concerning because he has quiet a lot of food allergies and the risk that he may get a hold of something that he wasn't able to have was high. Due to this we always had to put up baby gates in the doorway to were he was sleeping and around stairways so that we knew he wouldn't be able to get anywhere. Over time he has slowly grown out of this and now does not sleep walk any more but it was something that did seem pretty scary to me and my other cousins at the time, we always thought it would make the most sense to wake him up and have him come back to bed but my aunt and my mom always told us that that would not be the best idea. I was surprised to learn that even though there may be some risks to waking someone that is sleeping, it is not something that you absolutely shouldn't do. I think many people get there ideas from movies where sleep walking is shown, and in those movies they show the sleepwalker reacting poorly to being woke up. There is a clip of the movie "Step Brothers" that shows an example of this. Enjoy!
