9:00 pm Get Comfortable

It usually takes about 15 or 20 minutes to fall asleep, with the most comfortable position. Some people sleep on their backs and some on their stomachs. Most people curl up in a "fetal position" like a baby in the womb(子宫). Other people like strange positions like sleeping on elbows(肘部) and knees.

9:20 pm I am Falling Asleep

You're about to sleep when suddenly you feel like falling. You even dream you are falling off a cliff. Your body jerks(抽搐). What's happening? Well, you are falling-asleep. Your body relaxes, but your brain is still active and when your muscles become less tense, your brain senses that you are in danger of falling. To save you, your brain sends a signal.

10:00 pm Did You Hear That?

Soon a loud sound breaks the peace. What? You are snoring. When this happens, you breathe through your mouth, and as you take in air, it makes the soft tissue(组织) at the back of your throat vibrate(振动). The bad news is that you may snore more as you get older, especially if you are a boy. The good news is that snoring is not usually a serious problem, unless of course, you wake up your little brother or sister.

11:00 pm Better Lock the Doors

Some sleepers get really busy during the first few hours of the night. Sleep walking, sleep talking and even bed wetting can be caused by the disagreement between your brain and your body.

This behavior is a common among children, whose brains and bodies are still learning to work together.

4:00 am Dare to Dream

Nightmares(噩梦) or sweet dreams usually occur in the last hours of sleep. If you awaken in the middle of a dream, you might find it difficult to move for a moment or two. Certain parts of your brain have shut down, preventing messages from going to the muscles, temporarily(暂时地) disabling the body.

7:00 am But My Arm Is Still Asleep

Time to wake up, as you begin to move, a strange feeling floods down from your shoulder. Oh no, pins and needles! When pressure on your arm keeps the nerves（神经）from sending any messages to the brain, your arm loses all feelings. Don't worry if you wake up and your arm is still asleep. It'll be wide awake soon.
