Your brain

 How do you remember the way to your friend's house? Where do dreams come from? Your brain is in charge of these things and a lot more.
In fact your brain is the boss of your body. It controls just about everything you do even when you are asleep.

Your eyes

Your  eyes are at work from the moment you wake up to the moment you close them to go to sleep. they take in tons of information about the world  around  us: shapes, colors, movements and more. Then they send the information to your brain for process so the brain knows what  is going on outside of your body.
