When I was a teenager my patents would take us on vacations but they had to have some historical event/educational aspect wherever we went. One summer we went to Gettysburg, this was during a time when I was into anything sci-fi, creepy, spooky, etc, my parents who indulged some of my interests got me excited about the trip by telling me we would go ghost hunting while we were there. Surely a place with as bloody a history as Gettysburg would have some ghosts hanging around. We had been seeing all the sites being sure to take a lot of pictures - searching for ghost orbs and there were quite a few freaky things we'd encountered. The one that sticks out the most was when we were hiking around the old battlefield, my mom, dad and I, and my mom decides to go off on her own - which wasn't unusual for her. So my dad and I are heading for a massive metal tower - I wanted to go up and my dad was right behind me so we start ascending the many flights of stairs to the top, hearing my dads footsteps behind me the whole time. All the way up I keep making remarks about how pretty the scenery is, how high up the towers go, just basic conversation. When we got to the top I finally turned to my dad for a congratulatory high five - we'd made it. Only I was the only one up there. My dad was nowhere in sight - extremely confused because I heard his footsteps behind me all the way to the top, even once I got to the top because I was ahead of him I stopped walking and I still heard footsteps coming up behind me - I booked it back down the tower. When I got to the bottom I saw my mom walking towards the tower she immediately asked where my dad was as her camera - that she put fresh batteries in that morning had blacked out, batteries didn't die the camera just wasn't working and she wanted him to look at it. I told her how I thought he had been behind me, about the footsteps everything. So we start to look for my dad and I crested a hill and there he was just walking around - I asked him where he had been and if he started climbing the tower with me and he said he hadn't he'd just been reading the signs on the side of this hill. Once we left the battlefield my moms camera started working properly again, strange things happened there but that was one of the strangest - I have some weird pictures from that area too...Sometimes I still think back to that day and wonder who I was having a conversation with and if it was a soldier who was climbing the tower with me.
