I love legends like that.
Tonight I watched the first episode of Orphan Black, because David mentioned liking it. I was reluctant because in Sept of last year, my ex sister-in-law (who was a friend since HS) committed suicide by train. Awful, painful stuff. And I didn't want to see a scene like that. So a few weeks ago, late at night, I hear a train whistle, louder than I ever hear them here, and I've been here over 18 years. The whistle just goes over and over and over - again, that never happens. I look out of my bathroom window, and in one of a line of trees at the edge of my property was a blue-white light emanating up through the branches, like it came from within the heart of the trunk. It just wasn't a "right" kind of light. Nothing nearby could make a light that way, shining in that direction or dissipating upwards like it did.
I have no idea what it was, or what it meant. I sure didn't go out to check though.
