I used to not believe in ghosts, but in the last 2 years or so, I've started to believe they exist.
It sounds to me like you have a gift of some sort or a sensitivity. If you aren't afraid, you probably arent dealing with any kind of mean ghost here or anything. Maybe a kid died in your house at one point (sad). If you want it gone, I would talk to it and tell it that it's time for it to move on and that the house is yours now.
Good luck!
I think my house is haunted. but not a bad kind of haunting. We've lived here for 15 years. My neighbor said that an older man died in this house several years ago. At first, it really freaked me out. But then I realized, a ghost doesn't = posses you and take over your soul. It could be someone who was a wonderful person and feels like they still have work left to do. Like if my Grandma suddenly appeared in front of me, I wouldn't run screaming. So I figured just because I don't know this guy, why would I run screaming if he appeared for me? Now, if I saw a shadow person or something, THEN I'd be OUT.OF.HERE. haha.
My best friend, her aunt and uncle, and I went up to Gettysburg, PA last year. It was SO much fun! We are planning to go on the midnight hike at some point where you're almost gauranteed to see an orb or something of the sort.
