I must be anxious about something. Last night I kept dreaming about work. In particular I kept dreaming about being unable to do a particular task at work, about trying repeatedly to do it and not succeeding. It's an important task, a time-critical one and somewhat complex. It's also one I do speedily and flawlessly whenever it's required of me. In real life I can do this in my sleep. In my sleep I couldn't do it to save my life!
I finally gave up on sleeping around 5:30 and worked on fanfic for a little while, then played some Scrabble. At 7:45 as I was getting ready to leave for work when someone sent me an email asking me to - yes - do my dream task right away. I did it speedily and flawlessly and finished getting dressed.
