If someone says that they believe there was a ghost in your former self, they may believe you were reincarnated as someone else. This is something that people believe, but may not be proven with evidence.
That depends on how you know it was a ghost, and how you know it was Satan's ghost. People who claim to have seen a ghost do not - generally - know whose ghost it was.

If you believe in them, that is your opinion. They are real to you. For other people that don't believe in them, ghosts don't exist to them. People don't know if ghosts are real or not.
