Elevator prank in Brazil. Seriously though, I´d crap my pants too.

That was my entire point... If you were in that situation and a girl appeared next to you in an elevator and screamed like that, you wouldn't be looking at her reflection and thinking "Oh, she's not a ghost because I can see her reflection"

I was saying that Soulcat's post didn't make sense.

I completely missed his post.
Yeah, it makes no sense.
