The Woman In White And The Shadowy Figures?

Here lately strange things have been occurring around my house. I have been able to see spirits most of my life. We built our house about 5 years ago. My mother took care of an elderly friend in our house, he stayed at our home for about 6 months, and my mom took care of him. He moved out, and passed away right after the move. Weird things began happening, we have had things fly at us, and what not. (The man passed away in October)

A few months ago, my sister and I had gotten into an argument, she had thought that I kept opening her bedroom door. I had not been near her door. While in the hallway arguing, we both saw the door open itself. It did this twice right in front of us. I didn't see anything, no spirit or anything. We went and got my mother. She called out that if the one doing this was the elderly man, that he do it one more time so she knows. Sure enough, the door opened itself again.

At this time, I got a very uneasy feeling, and though I couldn't see anything, I knew that this was not who we thought it was. However, I couldn't figure out who it was. Well about a week later, I was in the bathroom getting ready to go to a friends house for the weekend, it was just my brother, my mom, and I in the house. I heard the sound of glass being shattered, and I automatically thought that it was something that my brother broken, so I called out, "what did you break this time bub?" Then I heard my mom say, "he is sitting in here with me, that wasn't you?"

I knew that something was wrong, so I stepped out into the hallway, and I saw my a picture of my step-fathers parents, shattered on the floor. It had to have been thrown from the wall, because it was no where near the location that it was hung. My mom got freaked out, to be honest so did I.

While we were cleaning the glass up, I saw something run in my mothers room. I got up, and glanced in there, then I saw a silhouette. I couldn't tell if it was a boy or girl, but It was short, so I assumed it was a child. I could feel its fear, and regret for knocking over the picture.

Nothing happened for a while. Now lately I have been seeing the same woman in our house. She is wearing a white gown, maybe a night gown, or hospital gown. It's really big on her. She has medium length blondish/brown curly hair. She doesn't say anything, and I feel no emotions from her. I don't know what she wants, or if she wants anything. But I do know that I have also seen a lot of shadowy figures since she has been there. I just want to see if anyone has any ideas as to what to do. Are all these spirits coming to my house because they know that I see them? Thanks for reading.
