It is impossible for a decerebrated individual to experience pain, pleasure, memory, dreams or thoughts of any kind. Therefore, this young man will be as unthinking, as unfeeling as the dead until the day he joins them.

Don't know whether I'm alive and dreaming or dead and remembering. How can you tell what's a dream and what's real when you can't even tell when you're awake and when you're asleep? Where am I?
