Nightmares tend to be more common among children and beome less frequent toward adulthood. About 50% of adults have occasional nightmares, women more often than men.
Eating just before going to bed, which raises the body's metabolism and brain activity, may cause nightmares to occur more often. Adults who have repeated nightmares that become a significant problem should seek help.
