  It doesnt! You are so right to question this! Your brain controls everything even your breathing so if it switched off we would all be in trouble! People used to think this was what happened but your brain is actually really busy when you are sleeping, it is making sure you keep breathing and it is sorting through all the information that you took in during the day! Your brain never gets a break!!
