I think my house may be haunted?

Ok, I think my house may be haunted. I hear things at night, and see dark shadows around my room. I can't be imagining things because even my brother has heard something. We have been hearing things since we were children. In a recent photo I took off my dog, I saw a (and don't laugh here) blurry shape that looks like a leg in the corner of the photo. This was took at christmas time, and we were all together in the same room. Iv'e even had feelings of someone touching my arm and my waist sometimes when Iv'e been in the bathroom. Sometimes I just get a feeling that someone is in the room with me. Sometimes I hear stomping up and down the stairs, as if someone is mad. Once, me and my brother were camping out in his room, and we heard the stomping. My mum and my brothers room have linked rooms, so as soon as we heard the stomping, we opened the door to my mothers room and she was fast asleep. Also, my mum once took a photo of me when I was about 1 or 2, and there was a dark object above my head. (Wasn't my shadow, you could see that on the ground) Sorry this has been so long, but could anyone please help me? I'm getting really freaked out.
