The average number of nightmares occurring in these adults is one nightmare per month or less (Rader 1). These nightmares are intense, however their effects are less detrimental to the health and well-being of the sleepers. The sleeper will experience all the effects of a nightmare, except that their daily functions will not be affected. Since average dreamers only experience a maximum of one nightmare per month, they do not suffer any psychological effects from dreams like a person who frequently suffers from nightmares would. Nightmares are something that every person will come into contact with at some point in their life. There are different groups of people who will experience nightmares differently from each other. The effects of nightmares on people's daily lives and psychological health also differ from person to person. The one thing that will remain constant though is the fact that nightmares are an eternal thing that people will remain interested in until the end of the story.
