Why do we need sleep?

The human brain is a very mysterious thing.
Most people dream, even if they can’t remember what it was about.
 We know this because scientists have tracked,
 the brainwaves
 of heaps of people when they’re sleeping,
 and it’s normal to have a really long period of REM,
 – that’s “Rapid Eye Movement” which shows their
brains are busy doing something.
 One idea is that dreams are a way of
processing and filing away all the sights,
smells, sounds, tastes and events of the day.
Perhaps your brain works out which parts to
 remember and which to forget.
If you have a problem, sometimes dreams can
 appear to reflect what’s going on – so if you
have a music exam and are a bit worried, you
might dream about being chased by pianos.
 Others think dreams are made of much
more random collections of thoughts
 caused by the brain randomly firing
 as you sleep. So if you’ve had a really
weird dream about the world made of jelly, well maybe that’s the reason?

  3. Hello Ava. I can really tell you turned the ideas of the website into your own words. Great job. I wonder what our brainwaves are like when we are awake? Next time you could try grouping your sentences into paragraphs.
