There is no certainty as to whether it is safe to take the Bloody Mary test or not. However, most people who believe in supernatural powers have taken this test and nothing has happened to them. Bloody Mary is described as a ghost game where Blood Mary is summoned while looking at a mirror in the dark and she appears to kill.
It is fine it is just a myth. It came from this girl who went to this school and saw her teacher get killed and that was her favourite teacher. That teachers name happened to be Mary. People have been telling that story for 100 years it is NOT true. Trust me I have done it.
Well, I recently heard of Bloody Mary and I think she is a complete myth! It's foolish, they spread a rumour just to scare kids. Sure it's safe to take it, it's fake. Trust me. Do it or not, your safe either way. Anyone can believe what they want, but I honestly think the Bloody Mary legend is fake, fake, FAKE.
