Yes - I have "school dreams" as the start of term approaches, stuff like the children walking around the room and I am trying to get them to line up but they are not listening they just walk around a bit zombified and it feels very stressful and such a relief when I wake up. And I always have "late to school and can't get through on the phone" dreams. Glad I'm not the only one. Also - first day back I am groggy as hell! I've just learnt to go with it the night before a new term - put a film on and enjoy rather than lying in bed stressing because I can't sleep.
