Seeing Things.

Do you ever have that strange experience where you see something out of the corner of your eye crossing the floor in your house? It’s usually dark, amorphous, and anywhere between a tennis ball and a football in size. For a moment you’re startled and mutter something like ‘what the f*** is that!?’ but when you look at it directly there’s nothing to see.

It happens to me quite a lot. I’ve read two possible explanations for it and I’m disinclined to embrace either, especially as the one I saw tonight was one of the bigger ones and it was crossing the floor of my bedroom.
