The Unsolved Story

I am really new to this site, but I will leave it off as a short story. But about 8 years ago I moved into this house in San Diego, it's in the far East of the area, we live in a pretty nice area, but when I stayed here for the longest I notice some pretty strange things going on. Like my grandma being tapped in the back, to the point of where I can hear married couples talking, I know for sure that the way they talk sounds a whole lot different, my sister said she saw a shadow in our garage, but she didn't want to talk about it, my brother said, he can hear a lot of things going on at night. My cousin told me that his niece used to live here before we ever moved in here, they said they have seen a lot of things going on in our house, to the point of it has gone mad crazy, but his niece couldn't tell him what happened or what was the explanation of this. I tried talking to his niece but she would never tell a soul about what really happened. That's why I called it the unsolved story that would never be explained. I would sense the ghosts watching me or even looking at me, but I can never see them at all. As of now, everyone is asleep, my TV's are turned off, and etc. The only thing that is on as of now, is my laptop and my lights, but I can hear the two married couples talking. It would really be nice if someone were to actually answer my unsolved questions. I mean for years, I have been wondering through my own house. I am not making anything up, this is actually something!
