would they already be born as ghosts?

Ha ha. That's just a fictional character based on imaginary character. I already entitled the story as "fictional",, which means that everything in this story is fictitious, they include : ideas, character and even the plot too.

I am a ghost???

It probably depends on how you view yourself as. But to me ghost is something that haunts us, a belief of past subsistence into the being of today.
Ghost is in our personal interpretation.

Thanks for the cordial reviewing.
