So lets just say that Sam and Dean are hunting a ghost, so they burn the body and such but the ghost is still killing people. So Sam does more research and discovers that the person was an organ donar, and that the ghosts heart is still beating in somebody else’s body.
WHAT DO THEY DO?
"And one day, you will see what you’ve become. A monster to society, A demon to your generation, A devil to your world. You will die and learn that there is no heaven or hell, only pain and beauty. Because that’s all we can really amount to. The beauty and pain we go through just to be perfect in one person’s eyes. So I ask you sir or ma’am, Under all that makeup and cakeup, What are you? Not to me, oh no. But to yourself. In your eyes. Believe what your are is beautiful. Or else, you will become what you think you are."
