This is kind of off topic, but I remember the time a friend of one of my exgirlfriends claimed to know all sorts of things about the afterlife/supernatural world. One of the points that she brought up was the "witching hour." She said this meant that there is a specific point in time where all spirits are more active across the world.

I then asked, "Do spirits know about timezones or daylight savings time? What about people that died before such concepts was introduced to society?"

She didn't like me much after that.
