Sense Sonnet - Chiller

Just Call Me Bloody Mary

I am a legend living long,
With variations of the way
I appear. There's no right or wrong,
Summoning stuff to do or say.
Mirrors and candles and darkened rooms,
Slumber parties or all alone,
I am the entity that looms,
Waiting to make my presence known.
It doesn't matter who I was.
It only matters that you yearn
Real hard to make me real, because
Only then will you really learn.

I know the legend may seem dumb,
But keep trying and I will come.
