A strange thing happens to nearly everybody at night. They turn off the lights，pull up the covers and close their eyes. Six or seven sleeping hours later，they wake up again. Strange，isn't it?

Sleep puzzles science. Scientists and doctors would rather talk about why one can't fall asleep. They are not sure what causes sleep. The best conditions for sleep are good health and meals neither too big nor too small. No worries and a comfortable place are important，too. They advise against two in bed.

Strange things happen during sleep. For example，they move often. You would feel tired if you didn't. You also dream. Part of your brain is still awake when you dream.
