I went on a hoaky ghost train ride at night thinking it was the stupidest thing but the tracks were laid over an old industrial area where lots of workers died, and it was a civil war battle ground as well - still had army barracks. I went on the last train ride of the night to hear the stories about the war, about when it was a big river boat stop, the wild west days, and the old caboose train car they had. I saw a woman in a victorian era black dress standing by the tracks with no head, white hands clasped at waist, moonlight reflecting off the material of her dress. I had been investigating ghosts for several years by that time and had never seen anything. That night I was frozen stiff. I could have touched her if I had been able to move. I kept thinking "It's just a tree" until we got to her and it wasn't. No one else saw her - but several people saw shadows rushing up to meet the train. I haven't investigated since. It's still terrifying to think about.
