I have. Then again, I had ghosts as friends when I was younger. I don't remember their names now because I was 5 or 6 when I had them but my parents remind me about it every time we watch something about Haunted houses or ghost hunting or whatever.
The story:I live in Atchison, which is considered to be the most Haunted town in Kansas. I live right next to a church that used to be a grave yard but they moved the graves somewhere else. I think they moved them to that area just past those houses not too far from the school... Ah i dunno. Anyway.. so yeah.. there you go. ^^x.. I hope you enjoyed my experience with ghosts.
You see we lived in this house on Kansas Ave. and I was had met these two, one was a boy and one was a little girl who were both around my age, a lil older i think. Well anyway, we were playing a game and I told her that she cheated. And that she lost, well she got mad and slapped me. Had a hand print across my cheek and everything. At the time my parents just thought that they were imaginary friends but when they came in to my crying and saw the mark they ask what happened. I told them that she hit me and they asked where she was so I pointed and they attempted to catch her... we moved not to long after that.
