I do. I swear one of my cousins has been replaced with another actor. A couple of years ago he looked like Ashley Cole, now he looks like Tim Cahill. It's fucked up man!
Also, whenever I was in peril on my travels in the summer there was ALWAYS a conveniently placed (most of the time English-speaking) person to help us. Seriously, if one chinese guy hadn't been where he'd been at that exact moment I'd probably be drowndead.
There was also one incident with my sister that absolutely confirmed it but I can't remember what it was, it involved her knowing something she absolutely couldn't have known at the time.
Anyone else suffer from a similar paranoia?
