Like see a ghost like being of the person the day before they appear. Or you just saw his spirit or looked into his soul that defines their personality.

I saw the "ghost" of my brother once, who's living. It's called a doppelganger but it wasn't a real person, it was a reflection and my brother wasn't even home at the time.
I used to have a lot of premonitions when I was younger but not about meeting people. Never had that but that would be freaky.
