Sleep Walking is an arousal disorder.  I am not sure but I think the cause \nis still quite unknown.  In children, it could be related to fatigue, \nanxiety and prior sleep loss.  In adults it's more likely to be related to \nreaction to medications or it could be a symptom of a mental disorder.

Sleepwalkers engage in their activities with their eyes open so they can navigate their surroundings, not with their eyes closed and their arms outstretched as parodied in cartoons and Hollywood productions. The victims' eyes may have a glazed or empty appearance and if questioned, the subject will be slow to answer or unresponsive.\nWhile sleepwalking itself does not inherently pose a health concern, accidents may happen as the subject is performing actions without the control of conscious mind.

Your question barely makes sense. You might want to re-wrie it. But if a person walks in their sleep and hits their partner in bed while sleeping it could be  because they have pent up or extreme anxiety during the day. Could always mean other things too. Abuse, no freedom, stress.

It is an evolutionary trend promoted by self preservation. Once asleep the male is able to have respite from incessant female gossip and tittle-tattle. He will be able to avoid the pitfalls of the loaded question and not have to participate in conversations that revolve around diet, fashion, celebrities, etc.

In my country they say it because it is believed that\n1. People with "clean conciences" sleep well \n2. Babies are all innocence so they have a clean concience\n3. Hence, Babies should sleep incredibly well... \n\n(experience also tells me... either babies aren't as innocent as we think... or a good night sleep has more to do with a clean diper, than a clean concience)

Well, first thing you are going to bed at a decent time but perhaps nine or ten would be more suitable. That way you can recieve more hours of sleep. \nYou springing up in your bed talking in another language could be considered as a form of sleep-walking. Nothing to be alarmed about. Sometimes our subconscious gets the best of it.\nBut try going to sleep earlier and if this happens again then I would suggest to explore it further.

If you mean how do we wake up.\n Before we go to sleep, we tell ourselves, consciously or not when we need to wake up, added to the usal or needed amount of sleep, plus the condition in which we are sleeping (eg intermittent loud noise, moving surface, soft-comfortable, hard surface, cold or hot environment...), how tired we are...all that is computed by the brain and we automaticlally wake up when the 'due' (computed total) time arrives.\n    Note that it has nothing to do with quality of sleep!

Scientists do not agree on the need for sleep.  But there are some theories:\n\n1.  It gives the brain time to sort and categorize the information it receives during the day.\n2.  It gives the brain time to receive no new data so that it does not enter a state of information overload.\n3.  It gives the muscles time to refresh with oxygen and nutrients from the food eaten during the day.\n4.  It gives the brain some "time off" when no new stimuli are being bombarded onto it.\n\n\nIncidentally, learn to spell.  Using "wut" in place of what makes you look like a dumbass.  If you ARE a dumbass then bad spelling is to be expected, because you are stupid.  If you are in fact NOT a dumbass, why would you want to be thought of as a stupid idiot.\n\nLearn English, spell properly, and stop following dumbasses who don't know how to spell.  Geeeez, you're an embarrassment.

do you sleep walk often?? I personally sleep walk when something is bothering me before I go to sleep. everyone is different . you need to figure out what your trigger is. sleep walking is very dangerous!!!!! I personally have woke up 2 blocks from my house. and the only way I woke up is I stubbed my toe on the sidewalk. and I was headed back.. so don't know how far I really got..

Talking in your sleep is called 'somniloquy'. It can happen with sleep walking. If you or someone you know is endangering themselves when they sleep walk, then a doctor should be consulted.\n\nSleep talking is a form of sleep disorder. Most sleep disorders are related to one or more of the following:\n\nstress \ndrug and alcohol use, including caffeine \nbad sleeping routines \ndepression or anxiety\n\nTry to reduce the stress in your life. Change can be hard, but getting support to work out strategies is a good start.\n\nTry some relaxation techniques. Cut out the drugs and alcohol. This includes caffeine, especially at night. And remember, some tea has more caffeine than coffee. \n\nGet some regular exercise. Try to do it during the day, as late night exercise can cause more sleep problems. \nAvoid large meals at night. \n\nGet your routine sorted. Go to bed and get up at around the same time. \n\nDon't do work or read in bed during the day - keep the bed for sleeping.\n\nTry the site below too!

Q: Why do people sleep at night?\n\nA: Before the invention of bulb and electricity, people used to use Fire for Lighting during nights. Which actually was costly and ineffective (as compare to todays' light during night). That's why it became the tradition to sleep at dark and sleep in the light (of the sun). Now, although we have a different ways to enlighten the nights, this tradition is still being followed as A WAY TO LIVE by most of the people in the world (more than 87%).\n\nAlong with the tradition, science proves that sleeping during night is 3 times more effective than sleeping during days.

Because you are falling -- falling asleep!  Why do you think they call it that?

perfectly normal\n\nBe aware that if you tell your parents about your sleep talking (although they probably already know) that they can ask you questions while you are talking in your sleep and you will answer truthfully, even if the question is something you don't want your parents knowing.\n\nOne side of my family is sleep talkers and it is really an amusing habit, but perfectly normal and very common.

Honestly I don't know how they sleep. Maybe they just turn off their conscience or ignore it. Who knows.

i think that what you say coming off of your sleep and your inner thoughts have some truth to it.it is truth because your inner thoughts and sleep talk are both from your conscious.
