Harry and the Midnight Ghost

I'm starting to think that my mother is coming for me. I have seen her now three times and it is starting to freak me out. First she came on the eve of my 15 birthday. But she came again last night. She keeps say murdrer and i don't understand .

We already found out that is was peter petegrew who back stabbed them not sirius but when she says murdrer all i see is sirius . I told her to leave me alone but she just won't.

The only times this happens is at midnight on the full moons and i can also hear Professur Lupin howling at the moon. Professur Snape has given us lots of homework since the exams are like 6 months away and Hermione is already done it all.

I've talked to Professer Dumbledoor and he says it is just flash backs from our forth year. I think is has a little to do with that but not alot .

Hagrid says i should just try and keep my cool, today Hermione kissed me on the cheek and said "Harry everything is going to be alright i promise". But how can i believe that.
