Dreams: Why We Dream

Summary

Dreams are a natural part of sleep, involving vivid experiences of images, emotions, and sensations. Most dreams occur during the REM stage of sleep, when the brain is most active. While the exact purpose of dreams remains unknown, some theories suggest that dreams help process information, practice learned skills, or even train the fight-or-flight response. Nightmares, which are frightening or distressing dreams, can be caused by stress or anxiety and serve as a safe way to confront fears. Although they are normal, frequent nightmares may signal a deeper sleep disorder.
