A childhood belief about ghosts

I learned the myth of Blood Mary when I was around 7 or 8. I had heard that if you scratch a mirror in the bathroom three times at the same time as chanting her name three times, she would come out of the mirror or the toilet or the sink and kill you with a rusty old knife. One of my childhood friends (now one of the most annoying "popular" people in highschool) and I went into the bathroom in the elementary school (we were at the After School Program), and we did it. Nothing happened.

Although nothing happened, I was afraid of bathroom for about a year or so, so I'd run away from it as fast I could after slamming the door. This subsided quickly once my mother told me I wasn't going to die from "Bloody Mary."

This fear of anything that can hold water was re-instated after I saw 'The Grudge' in theaters. My friends didn't help very much. Similar to the first fear, this one gradually subsided over a year's time.
