Some people are born with two "brains". Usually, the brain halves are connected and communicate with each other. Sometimes they are partly connected and rarely not connected at all. The movie "The Rain Man" is about a person like that. The people with partial connections, we have labeled autistic.
A actual person with two actual brains would have an extremely difficult time dealing with the world we know. If you ask the question on this site about autism, there is a great posting written by a person with autism and how he sees the world.
