Backstory

I'm not sure how I died. One day I was alive and then the next...dead. I didn't even know I was dead until I walked into class and everyone started screaming. Having 'slept' in and rushed out to class I hadn't looked in a mirror to notice I was see through, and I hadn't felt any different.
I don't even know who did it. No one does. The Auror's did an investigation but couldn't find anything. They're saying I probably died in my sleep but my body wasn't in me bed. In fact, they haven't found my body yet, the only thing we do know is that I died on the school grounds because as a ghost I'm trapped here.
Thats right ladies and gentlemen I'm living the nightmare, eternally trapped at school.
Its not all bad I guess, It's very easy to play pranks on people now, Peeves has shown me a lot of tricks. I've mapped out every inch of this castle in boredom and have discovered I can get as far as the Forbidden Forest before I'm yanked back.
Usually I end up in the Slytherin common room feeling shaken and weak so I tend not to do that to often. Why the Slytherin common room? Well. I was a Slytherin 7th year when it happened.
