I've experienced a lot of strange things but probably the weirdest happened in a hospital a few years back. I was in an old wing of a hospital going to an area for some kind of check up. I had to go to the bathroom and there was one in the lobby but it was occupied. It was an old fashioned kind with the sign that says Vacant/Occupied when you go in or come out. Part of the lock.

There's no one else around and I'm waiting and starting to get....anxious. Then I hear the sounds of finishing up in the bathroom. Flushing, water running, paper tearing - all that stuff. So I wait....then the vacant sign flips on. But nobody comes out. I wait. NOBODY COMES OUT. So I figure, maybe the person had a problem. So I knock on the door and go in. THERE'S NOBODY IN THERE. And it's a one seater. No other access in or out. No window. NOTHING. Just the drain in the floor.

I can think of a lot of things to do in the afterlife....but I hope I'm never reduced to haunting a toilet.
