Sleep is a condition of body and mind which typically recurs for several hours every night, in which the nervous system is inactive, the eyes closed, the postural muscles relaxed, and consciousness practically suspended. When you sleep you're practically unconscious, but your organs still work, even your body and other parts of the body will still grow.
Children need at least 10-11 hours of sleep a day, and teenagers need at 8-9 hours of sleep. The reason that children and teenagers need so much sleep is that so they can rest, grow and regenerate. If they don’t rest for the recommended hours of sleep then the outcome will show in their appearance, personality and mind.
As you grow older, and older you won’t need as much sleep as you did when you were younger, depending on your lifestyle. By depending on your lifestyle, I mean if you’re an adult and you live a healthy lifestyle you won’t need as much sleep, but if you live an unhealthy lifestyle then you may think you might need more than you would if you lived a more healthier lifestyle.

You’re body will heal the scab and then when scab has healed the skin will fall off, or slowly peel off. While you sleep your brain also has a little cleaning spree, storing all of the important short term memories into your long term memory so you don’t forget anything important.
Sometimes when you fall asleep and you’re thinking about something straight before you do so, it is likely that you dream about that certain subject. When you dream it doesn’t necessarily make sense, so don’t be confused if you dream about something so bizarre you think you’ve gone crazy. Most of the time when you dream you don’t remember the entire dream and sometimes you don’t even remember you had a dream, but don’t fret this is completely normal. But what is normal when it comes to dreaming?
