Dreyer was born the second of three children of a principal and a teacher.^[2] Following a year as an exchange student at Claremont High School in California in 1977,^[3] and her final Abitur exams at the Käthe-Kollwitz-Gymnasium Neustadt in 1980, Dreyer started her English studies and Roman Catholic theology at the University of Mainz. The following year she switched majors to jurisprudence and graduated with the first Staatsexamen in 1987 and the second Staatsexamen three years later with an excellent academic record.^[2]

From 1989, Dreyer worked at the University of Mainz as a research assistant to Professor Hans-Joachim Pflug.^[4] In 1991 she received her appointment as a probationary judge, and later as a prosecutor in Bad Kreuznach.^[3]
