The textbook has a short section on sleepwalking and some of the crazy things that people have done while possibly sleepwalking. As another example I ran across this news video about a man stabbing his wife while sleeping.
I would like to know more about this case, but from what I find he has no memory of doing this, however his actions were analyzed by a doctor and he concluded that they were similar to that of an awake person. The man has had a past of sleepwalking, but the actions were different this time, and he had confronted his wife about an affair multiple times leading up to the attack.
This and the text lead me to ask the question: How do people continue to stay awake through such events". This man and others should become awaken through movements and noises it seems. Are these people dreaming and acting that out only some of the time. I wonder if there is something different biologically when people sleepwalk like the changes that occur through the different stages of sleep. Otherwise it would seem like sleepwalkers should always do it instead of just sometimes.
In cases like this it makes me wonder how we can determine if someone is asleep or awake during certain situations. The courts do their best to make sense of it, but in reality who knows? Testing is probably pretty difficult on these patients, which leads to just another innocence plea that people can use. Insanity pleas are well-known through movies and other cases, but for people to use psychology as an escape to freedom seems tough to grasp. I like the quote from the movie Case 39, "Do you remember when people were just bad".
There are so many psychological "problems" that affect people's behavior that it is almost impossible now to state a specific cause and effect. Sleepwalking is just another example of an altered state of mind that I believe requires more research and development.
