The nightmares are all the same. I wake up at some ungodly hour after dreaming about a looming final exam. Math was my worst subject, so the test will invariably cover numerical concepts never understood in classes sparsely attended. Some hate to have their sleep interrupted, fearing that there will be no more. In my case a sleepless night is better than the agony of a cruel dream that just won’t die. And the odd thing is, the last time I attended school was during the Clinton administration.
