Helen via Ouija
My mother and I were using my Ouija board on Halloween, a couple of years ago. When we got bored with asking random questions about the future, I (sort of jokingly) asked if there were any spirits in the room. It instantly said Yes. I asked for details.
The spirit said that her name was Helen, and that she died in a train crash near where I lived in 1856. She even told us she was a 35-year-old teacher.
I looked the information up on the internet later, and I was shocked to learn that everything she said checked out. There was a terrible train crash in Ambler, Pennsylvania on July 17, 1856, killing about 60 people. It was a train filled with Sunday School children and their teachers. And before you ask, there's no way my mother knew about this or set it up. She was too freaked out!
I tried to find Helen's name on the list of victims, but I couldn't find a complete list, and she never gave me a last name. I never heard from her again - I figure she just wanted someone to talk to.
You can find out about the crash if you just look up the Great Train Wreck of 1856 on Google.
