2. The Grey Nun of York
Some people say she haunts the room behind the dress circle in the Georgian Theatre Royal, some say she wanders the site where she was caught and some people say she roams the pubs in York scaring gents in the loo.
She is just the normal run of the mill ghost because all she does is appear and disappear while looking grey and eerie.
But her backstory goes like this:
She was a nun in the Middle Ages and she fell in love. People believed she fell in love with a nobleman or a soldier that was guarding the monestary at the time. Their love was mutual and they actually attempted to elope.
But sadly they were caught by the Order and given grave punishments. The man was was hanged while the nun was starved to death. They imprisoned her in the monastery walls while some say she was locked in a windowless room to die.
