I want a nightmare

 想做坏梦

Before the final examination, Tom told his mother, "Mom, I had a dream last night that I'd passed today's exam.""Don't trust dreams, dear. It is said what you experience in dreams usually turns out to be the opposite." Mother replied."Then I do hope I'll fail the other subjects in my dream tonight," Tom said.

在期末考试之前，汤姆告诉他的母亲：“妈妈，我昨天晚上做了一个梦，梦见我通过了今天的考试。”“不要相信梦，亲爱的。据说梦中的经历通常与现实相反。”妈妈答道。“那么，我真希望在今晚的梦中，我的其他功课都不及格。”汤姆说。
