Nightmare

A nightmare, also called a bad dream, is an unpleasant dream that can cause a strong emotional response from the mind, typically fear but also despair, anxiety and great sadness. The dream may contain situations of discomfort, psychological or physical terror. Sufferers often awaken in a state of distress and may be unable to return to sleep for a small period. Recurrent nightmares may require medical help, as they can interfere with sleeping patterns and cause insomnia.
