You had to bring this up before my coffee... I have, on several occasions, have even recorded voices (EVP). My parents house is built on land where a revolutionary battle was fought, many died. When I was younger we would go in the woods and find artifacts from that era which we would take home, some of which were taken to the local college and then donated to museums. But one particular case, when I was about 11 or so, I woke up to see just the face of a soldier in front of me, he had his military hat on, was like 2 guns criss/crossed on the hat and his teeth were all yellow and sharp. No it wasn't a nightmare lol I screamed and parents ran in blah blah .. I would love to get some people near me and do a ghost hunt (Philly area) ..
I'll get into how I saw the Devil when I was 4 later.. <g>
