Has anyone acually seen bloody mary?

she is soposed to be sombody who got murdered and soposedly if u chant her name in the mirror three times u will see her. some stories say different ways to make her come out of the mirror. also some stories telll that if u c her she might scratchu , kill u ,or ask u questions and if u get them wrong u die. onother is that if u dont c her in the mirror she will come to u at night or wen u r taking a shower turn the water into blood. personaly i think she is a myth. for one i am a cristian and dont believe in the stuff and for two i hav done it and nothing period hapeened at all!!
