"Do you ever know anyone who… can see ghosts like me?"
"Hmm? No. Never. Not even once have I heard.
Exorcists, supernatural experts, or even people who claim that they can 'See' ghosts, are actually merely sensing the ghost's existence through the soul. They are only 'Feeling' the presence of the ghosts, but in reality, they couldn't see them at all.
A 'Third Eye', one might call it. But in reality, it's not an eye, and it doesn't allow you to see anything. A proper naming would be called the 'Sixth Sense', and it exists inside our souls. It allows us to sense the activity of another mystical entity similar to our souls, even the ones that are already dead."
Celine explained, and so far, her explanation seems legitimate. I've never heard of anyone actually seeing ghosts. The act of seeing ghosts is mostly made up, just like in movies. When in reality, people can only sense the ghosts and could only communicate through certain methods.
