Yep, I've had the missing classes dream before, and also the Surprise Exam In a Class I've Completely Forgotten About dream. Plus there's the Surprise Work Project That's Suddenly Due dream, and the Place That Should Be There But Isn't dream, and let's not leave out the I Forgot to Feed the Hamster and Now It's Dead dream, which THANKFULLY I have not had in a very long time. OH OH AND HOW COULD I FORGET THE CLASSIC I'M BEING CHASED BY AN ELDRITCH HORROR FROM BEYOND ETERNITY AND IT'S LIKE I'M STRUGGLING THROUGH QUICKSAND DREAM? :DDD

That is interesting about a surge in anxiety dreams! I did read somewhere recently that more anti-anxiety drugs are being prescribed ...
