Ah sleep, so peaceful!

So, why do we sleep?

Well, first of all every animal with a brain sleeps.  A lot of really important things happen while we are off in dreamy dream land. Sleep is when the body gets a chance to repair and process things.  This allows our brain to be refreshed and our cells (throughout the body) to get repaired,  an important part of how wounds heal!
