This inequality decreases with aging because of a less high prevalence in elderly women. [5] The rate of nightmares increases from ages 10–19 to 20–39, and then decreases during the ages of 50–59. [8] The rates of nightmares for men increases from ages 10–19 to 30–39, and then decreases at the age of 50–59. [8]
