My house is haunted, how do i stop or rid this ghost from me?

Ok well since moving into my home I have noticed strange things happening. Just recently I have noticed this ghost is becoming aggressive now. One day as I was walking up the stairs when suddenly a huge gust of wind nearly pushed me down the stairs. All doors and windows were shut and there air was not in so I could not find the source of the wind. After the wind a picture frame with a photo of me literally flew off the wall. It did not fall because If it did it would drop straight and not at an angle leaving it across the room. Then that night something pushed my heavy virgin Mary statue off my nightstand. I was the only one in the room. Then a few days later my door will open and close when I locked it and my lights flicker. If anyone knows how to help me I will appreciate it! Thank you for listening and answering
