Ghostly Acquaintance

It all started this one night at my grandfather’s mansion, it’s an experience I will never forget.
My grandfather died a few years ago and left me his mansion. I didn't think anything was wrong with it until strange things started to happen that made me think twice about the mansion. I just left it for a few more days, but it got worse. Weird things were happening every single night, as soon as the clock striked twelve.
I have only ever told 1 person about this but he thought I was nuts. So I never told anyone else, but here I go.
