Frequent nightmares may worsen the quality of a person's life. Nightmare sufferers may try to avoid sleep, which causes sleep deprivation, resulting in increasing intensity of nightmares. There is often insomnia, fatigue, and reduced performance during the day. Finding the causes of frequent nightmares may help people suffering from them and also facilitate psychotherapy.
The research topic of this study is to explore the associations between some personality traits, such as absorption or boundary permeability, and nightmares in people with and without frequent nightmares. Apart from personality traits, other variables that may influence the frequency of nightmares will also be monitored. They include experienced distress, depression, anxiety or somatic symptoms, and symptoms of experienced trauma.
