I never get confused, you've misinterpretted the definition of Derealization. It's the sensation that sometimes I get when realithy feels fake, it's hard to explain, but everyone has it sometimes, almost anyone can relate.

Like, you've never just stopped and thought about life, the world, etc? You get this feeling like your out of it, like everything feels like a dream. I always know it's not, so it doesn't really affect me. Its just odd. Can anyone relate?
