I often have what I call 'Struggle Dreams', always involving sorting out a problem,searching frantically for something,or making some ghastly mistake and having to backtrack to rectify it. They don't exactly 'haunt' me, but I wake up a bit tired, as if I've done a night's work, not rested. I sometimes wonder if it's due to my long teaching career, which involved sorting out no end of 'stuff' during a school day.
