Many years ago, something STRANGE happened in this graveyard,what do you think this was??

the tingles you talk of, ive had happen to me, when a spirit was making contact with me....its happened quite a few times...the tingling sensation is quite strong in parts of your body...ive never heard of it happening from standing on someones grave, but then why not...if its the same feeling of tingles, its quite a different sensation, and you know straight away something is happening out of the ordinary........yes the answer above is quite correct.....spirit touching you gives those tingles...(not goosebumps)
