Context: H.A. learned about this legend and the corresponding game in the early to mid 2000s while at elementary school.

H.A. : Alright, so, Bloody Mary was a little game that my friends and I would play when we were in like fourth, fifth grade? And um yeah so basically we would turn off, and because we didn’t have anywhere to go we would do it in the bathroom.
P.Z. : In your house? At school?
H.A. : At school. Okay, at school. And um we would turn off all the lights, there was, it’s actually kind of funny, there was still light from outdoors, so there was no way around that. So it wasn’t completely dark, but ideally you’re in a completely dark room and like you hold a candle in your hands. And um basically one person, a designated person, is supposed to say, is supposed to stand in front of the mirror and say “Bloody Mary” three times, and then when you open your eyes, Bloody Mary is supposed to appear, and she’s supposed to like pull you into the mirror. Or legend says. Never happened to us, good thing, but we’re, um, we’re, we’re safe, but a lot of girls at school were doing that a lot. And the principal got concerned and it’s basically banned at our school now.
P.Z. : Gotcha.

Thoughts: This was very similar to my own experience. The only difference in my own version is what happened after Bloody Mary appeared. However, this is a fairly popular story that I think is and will remain popular for years to come.
