I have had nightmares about having to go back to work.
We just had a storage shed (6'x10') built about a week ago, and because we plan to keep a small upright freezer out there, we want to insulate the walls and ceiling and put up something like paneling to keep the insulation in place.
I woke up for the bathroom last night and then stewed about doing that job for the next hour before dropping off to sleep again. So, I guess I had an awake nightmare.
