From a post over on kottke.org, Tiny Private Mind Motions
“Every morning, when I screw the lid onto my steaming thermos of coffee, I think to myself, automatically, the phrase “heat capture.” I have no idea why. I’ve never used that phrase in any other context in my life. And yet I couldn’t stop it if I tried. After years of this, I finally mentioned it to my wife, who revealed a similar habit: Every night, when she shuts the bedroom blinds, she thinks to herself the ridiculous words, “Sleep Chamber: Complete.” She said she kind of hates it because it makes her feel as if she’s living in an episode of “Star Trek,” but she has no choice.”Sam Anderson, New York Times
I have this kind of stuff happening all the time. Has for years. Glad I’m not the only one completely out of control of what happens to pop into my head at any given moment.
Of course, I can’t think of a specific example right now, even after a few minutes of trying because the Universe has a dark sense of humour.
