A childhood belief about ghosts

I used to believe in bloody mary. My friends were older than me, and some believe in bloody mary also. WE thought that if you went into the bathroom and did the bloody mary chant (about the baby and stuff) she would come and get you. So when I was younger than first grade, If I took a shower or something, I would leave the door partially open incase bloody mary came. Monsters never scared me, just bloody mary and freddie kregur(spelling aiight??)
