I had a bizarre experience in a small graveyard in New Jersey. I was with my dad and we parked the car and got out to check out the graveyard. There were only about 20 headstones and they all dated back to the mid 1800s. Then we were walking down the road a bit and out of nowhere came this group of people - a few adults and a few kids. They were all dressed in very old fashioned clothing and had completely straight faces and they didn't acknowledge us at all. It was really weird. When we walked back to the car a few minutes later, they were no where to be seen. We drove up and down the road a ways looking for them, but they were just gone.
Even though I was there and saw this for myself, as I sit here typing it I think it sounds ridiculous, lol.
