The Curious Incident of the Note In the Night Time

Last night, I got out of bed, found an ink pen and my 'To Do' list/pad and scribbled

"What were you thinking?"

pretty as you please right down the center. I would like to think that was something I did long ago that I'm only finding now, but woke up with a pen in my bed. Some people sleepwalk, I sleep think. No wonder I'm always tired.

I do wish I knew what on earth I was talking about though.
