there's another way...
... to contact mary. u have to go to a mirror at mid night with all of the lights off and then turn ur back to the mirror and say bloody mary 3 time. then u turn around and u will see her. it doesn't work but thats the way i've heard it. i also know another way to make u see bloody mary in ur mind but i don't feel like explaining the whole thing because there are a lot of steps to do it. good flash by the way u got mary's description right.
