Is my house haunted by ghosts?

[Will]

So I never use to want to do with anything about the un explainable. But I just get very scared in my house. So I have lived in my new house for about a year now, and everything use to be fine. I am a early teenager so I didn't think much of it. But now I can just feel that a ghost or something is in my house. The most places I feel that a ghost is, is my bedroom, the upstairs hallway, and a few other rooms, including the basement. Most of the time when I first get into my bedroom I can just have a feeling that a ghost is in my room. Sometimes I can kinda see like a shadow in the hallway. Now I can see through the shadow, bit I know some one or something is there. One night when I got out from under my covers, I heard a thud on my floor or my wall. So I hid back under my covers. I feel better when I am under my covers, because I believe that I have successfully blessed them. When I got back out of my covers I heard a bang in my room, louder then the first one. I just keep getting weird feelings and unusuall sounds in my room. Now I do have a brother and his bedroom is on the other side of my wall. But everytime I hear these things is when everyone is asleep. I can actually feel that there are a few ghosts in my room right now. If I tell my parents they will just say if I see one I'll believe it, or don't worry I don't see or hear them. Ya how supportive are they. And I mean it this is real I hear them and sense them. I am scared. So is there any advice you guys can give me to help me calm down, or get them out if my house without upsetting them? Can u guys also tell me what else could cause these sounds? Thank you guys soo much! I need. All the help I can get or I will Lois it!
