During sleep your eyes don't send visual data or information about images to your brain. In fact, it takes almost 30 seconds for the connection between your eyes and your brain to reboot when you wake up. This is why it's often difficult to see complete and clear images when you first wake up.

Where do our minds go when we sleep?

Our brain during REM sleep is fully active, guzzling as much energy as when we're awake.
