Explanation
A nightmare is a frightening or upsetting dream that happens while you are asleep. It can make you feel scared, worried, or stressed, even after you wake up. Nightmares often include situations that feel dangerous or uncomfortable, like being chased or losing something important. Children and adults can both have nightmares, especially when they are sick, stressed, or have watched something scary. Most nightmares are harmless and go away quickly, but they can interrupt sleep and leave a person feeling tired or anxious in the morning.
