I don't remember this personally but it's one of my parents go-to stories whenever this kind of thing comes up. Our house is really close to a graveyard, it's not creepy or anything it's just a nice grassy area which happens to have gravestones in, so everyone walks around there a lot. Apparently when I was about 4 me and my mum were walking through it when out of the blue I just asked "can I go play with that boy?" It's not unusual to bump into other people so my mum didn't really think anything of it and looked around to see where I meant. "Look by the stone" I said again pointing backwards at a tombstone about 50 or so yards behind us. There was literally no-one else in the graveyard. Apparently my mum just freaked out, she says she grabbed my hand and half ran all the way back home and we didn't walk that way for a good few weeks.
