We've all heard the legend.  Stand in front of a mirror, say her name three times, and wait for her to appear.  But where did this eerie childhood game come from?  In this episode, we peer into the dark origins of the Bloody Mary myth, and uncover the real historical figures who may have inspired the tale. Is it just a spooky sleepover ritual, or is there something more lurking in the reflection?  Turn off the lights, face the mirror...and press play...if you dare.
