Help me understand nightmares and dreams.

Dr. Kristi Pruiksma discusses nightmares and their prevalence among individuals who have experienced trauma, particularly active duty service members and veterans. She explains that nightmares are vivid dreams with intense emotions that often wake up the sleeper. She also highlights that nightmares can be different from dreams in terms of content and emotional impact. Dr. Pruiksma explores conditions that mimic nightmares, such as sleep terrors and nocturnal panic attacks, and discusses the treatment options available, including medication and behavioral approaches like imagery rehearsal therapy.
