i know it's a weird question but ihave always been curious.

Answer 1

yes there appears to be five stages, and when you are woken you go back to stage one.... most nights sleep would repeat the cycles about 6 times in the night.

The Sleep Process

As we fall asleep, we enter the transition sleep called Stage 1 and begin our first sleep cycle. Within a few minutes we go into our Stage 2 sleep. Stage 2 sleep is where the other three stages come from. Within 15-20 minutes we have gradually evolved into Stage 3 then Stage 4 sleep. Stages 2, 3, 4 are called delta sleep or NREM (non-rapid eye movement) sleep. Our respiration and heart beat slowdown during these 4 stages.

Our body also becomes immobile. After almost half an hour of NREM sleep, our brain goes loco and we go back to stage 2 sleep and then go to REM (rapid eye movement) sleep where our brain becomes very active and our respiration and heart rate increases again.

This is the stage where our dreams occur. Our eyes also move in all directions under our eyelids. The REM sleep will happen for only about 10-20 minutes and then goes back to stage 2 again. This marks the end of the first sleep cycle and then starts all over again.

As we start all over again we gradually loose our time for NREM sleep and replace it with longer alternating stage 2 and REM sleep and by the final sleep cycle, we will spend about half our time in stage 2 sleep and half in REM sleep. Sleep normally ends after six cycles.

What is REM (and is it important)?
Sleep is an ordinary part of living and people go to sleep every day. This is perhaps the reason why people take sleeping for granted. When people are asleep, does it follow that all their body parts are also asleep or are there some body parts, especially the brain, ,that remains awake?

Simply said, does the brain cease to function when a person falls asleep? Is REM or rapid eye movement connected in any way to brain activity even while a person is asleep?

People who have normal sleeping habits usually undergo five stages of sleep. The lightest quality of sleep is in the first stage. Most people spend more time in the second stage while stages four and five are considered that stage when the person is already in deep slumber. Children usually experience wetting their beds and sleepwalking during these periods. REM sleep is known as the fifth or the last stage of sleep and it is characterized by rapid eye movement.

Rapid eye movement is associated with a physiological condition which is said to occur when a person is asleep. This physiological condition, said to occur every ninety minutes of sleep time, is characterized by rapid eye movement, rising heart rate, and heavy breathing.

There are scientists who believe that dreaming and rapid eye movement are related. Dreams are actually proof that a person’s brain is active even during sleeping time. Scientists explained that dreams are images that are influenced and sent by brain signals.

The condition called REM sleep is actually triggered by the emission of brain chemicals identified as acetylcholine. While REM sleep is switched on by acetylcholine, it is switched off by brain neurotransmitters known as serotonin and noradrenalin.

The scientific explanation that dreams or REM sleep is triggered by acetylcholine and is switched off by other brain chemicals proves an earlier theory by Freud wrong, that dreams are not useless images but they have meaning. Some scientists believed that dreams are merely products of brain processes.

REM behavior disorder (RBD) occurs when someone acts out a dream in his or her sleep. Usually when you dream, your muscle tone is decreased – you are, in fact, partially paralyzed. In rare instances, some people do not have a decrease in their muscle tone and begin to act out their dreams.

In addition, the dreams frequently become more violent than normal, and are often described as nightmares. The classic situation is one in which someone wakes up punching a pillow and remembers dreaming he was in a fight.

RBD is very rare, occurring most frequently in older men. Common causes of RBD include the use of certain medications (especially anti-depressants such as Prozac and Paxil) and withdrawal from certain sedatives (such as alcohol).

RBD can also be associated with Parkinson's Disease, narcolepsy, and certain other neurologic diseases (e.g. rare brain degeneration disorders, strokes in certain areas of the brain).

Usually, however, the cause is a mystery. Fortunately, there is effective medication for this problem.

Answer 2

People have different opinions about the stages of sleep. But they're not necessarily correct for everybody. Every individual's sleeping habits and duration are different than others'. Some people don't get up to use the toilet, some don't wake up for drinking water. According to one theory, each one of the 3 steps i.e. falling asleep, dreaming & waking up lasts 2 hours. That isn't correct either. It takes me about 3 hours to fall asleep and I never dream. And no, your question isn't weird. You should always ask about what you don't know. Don't feel shy or think that your questions are strange.

Answer 3

I have heard of three stages of sleep. the falling asleep, the dream stage and the waking up. Each stage last 2 hours and yes you start over everytime you wake up

Answer 4

The answer is for normal persons with normal sleep patterns you do start all over again. When we sleep we go through several sleep stages. The deepest stage being Rapid Eye Movement (REM Sleep). REM sleep is the dream stage and involves a kind of paralysis of the body.

It is normal to awaken during normal sleep patterns. Usually we go back to sleep and start the process all over again.

It is not a weird question. We spend one third of our lives sleeping. Sleep study labs are relatively new in medicine and they are growing rapidly as more and more people are turning up with distrubing sleep problems such as narcolepsy, sleep apnea, restless leg syndrome, insomnia, and others.

Answer 5

Everybody is different , I 'm not sure the answer but I wake up 2 or 3 times a night ,I have even got up, went to bathroom in the middle of a dream ,got back in bed and picled up where I left off in my dream, every body's different

Answer 6

i definately learnt the 5 stages of sleep in my psychology class.
well, i think we go back to the stage where we left when we woke up but it depends on the situation. If we felt very much awake, we go back to stage 1 but if we felt like we are still sleeping but only woke up bec we really need to go to pee, then, we most likely continue the stage.

Answer 7

ok, you like to sleep or not sleep? reason you assert the two. Your ingesting, which will positioned you to sleep, and based how lots you have had, additionally make you too impared to tension in some hours. be careful. Sleepy+ingesting=a great risky driving force, able to killing an harmless on the line

Answer 8

I heard that if you don't let yourself completely wake up, you will pick up where you left off, so just try to go right back to sleep after your interruption.

Answer 9

Sorry doc once you wake up you have to start over again.

Answer 10

huh ... I don't understand the question.
