Sleepwalking（梦游）

Not all sleep is the same every night. Weexperience some deep, quiet sleep and some active sleep, which is when dreamshappen. You might think sleepwalking would happen during active sleep, but aperson isn't physically active during active sleep. Sleepwalking usuallyhappens in the first few hours of sleep in the stage called slow-wave or deepsleep.

Not all sleepwalkers actually walk. Some simplysit up or stand in bed or act like they're awake when in fact, they're asleep!Most, however, do get up and move around for a few seconds or for as long ashalf an hour.

Sleepwalkers' eyes are open, but they don't seethe same way they do when they're awake and often think they're in differentrooms of the house or different places altogether'. Sleepwalkers tend to goback to bed on their own and they won't remember it in the morning.

Researchers estimate that about 15% of kidssleepwalk regularly. Sleepwalking may run in families （在家族中世代相传） and sometimes occurs when a person is sick, has a fever, is notgetting enough sleep, or is stressed （紧张）.

If sleepwalking occurs frequently, every nightor so, it's a good idea for your mom or dad to take you to see your doctor. Butoccasional sleepwalking generally isn't something to worry about, although itmay look funny or even scary （骇人的） for the people whosee a sleepwalker in action.

Although occasional sleepwalking isn't a bigdeal, it's important, of course, that the person is kept safe. Precautions （预防措施） should be taken so the person is less likely to fall down, run intosomething, or walk out the front door while sleepwalking.
