Maybe in life you've always wondered why you couldn't walk through a mirror, that all you could do was see this reflection of yourself one you weren't sure if it was real or a figment of your imagination.

Maybe that reflection you see was more than a reflection. It was an alternate you, an alternate world one of evil, while you were stood there in this world of good.

Maybe a mirror was reflective so you couldn't see what was truly there lying on the other side of this mirror of lies.
