Graveyard Entities

I just started experiencing whatever is going on, and it is really scaring me. A few weeks ago, my sister and I went to the local graveyard to test out this ghost radar I got in the appmarket for my droid. (That's my phone if you didn't know) I didn't think it would really work. It's just a circle with lines around it and a scanner and if there is a so called "apparition" nearby, a dot appears on the scanner in the direction it is.

There was a slight breeze that day and it was sunny. We got near the graveyard and the scanner started going crazy. Dots were appearing everywhere, red, yellow, and green dots. The colors meaning the strength of the so called entity, red being the most present and green being the least. A word or phrase appears at the top of the screen sometimes, like something to do with their death or whatnot. A large amount of phrases and words began appearing, some names and some frightening words like "hanged" or "murder".

The creepiest part of the whole equation was when a name appeared. The name was Peter. My sister and I started wondering if the Peter that appeared was an inhabitant of the graveyard. We started looking at gravestones and we actually found one that said Peter Longs. It was a little scary, but then again there is a lot of people named Peter in the world. We started talking to the so called spirits, like I said, "Is there anyone here with us that would like to share things via my radar?" I started getting replies like crazy, random words and phrases were blazing around like a wildfire. We then started to go home because it as getting near dinner time.

Everything was good from then on for about 2 days. My whole family started hearing footsteps, knocks, bangs, etc. My sister said that she heard her name called and then a bottle of her perfume flew off of her shelf and across the room. I later starting seeing shadows and hearing muffled talking in the room next to me, even when nobody would be in there. Everything was starting to scare me so I spoke out to them and told whatever was plaguing my family that it had to leave my home. Everything was quiet and back to normal until the next night, when was laying in my bed trying to sleep. I felt really cold, all of a sudden and my TV turned on really quick and then it turned back off again. I went to my sisters room and I saw her sitting up in her bed looking really frightened. I asked her what was the matter and she said that her TV turned on and off again. I told her that the same thing happened to me. We were both scared as can be so I just slept in her room that night.

The most recent and scariest experience I have had was when I was home alone one night because my family was out at the store and I didn't want to go. I was just watching TV and then the channel flipped. The remote was all the way across the room when that happened. Later I got in the shower and as I was washing my hair I heard a knock on the bathroom door. Then the door swung open and one of the knobs on the cabinet hanging on the wall fell to the floor. I was so scared that I called my mom and I went to my neighbors' house until they got home.

Everything that is happening is really scaring me and I was just wondering if it had anything to do with the graveyard or anything else. I don't use Ouija boards or anything of the such.

If you could help me on how to get rid of these things in my house it would be greatly appreciated.
