Nightmare
From W8MD weight loss and sleep centers
A nightmare is a disturbing dream that often causes the dreamer to awaken in a state of fear. Nightmares can be caused by a variety of factors, including stress, anxiety, and traumatic events. While most people will experience occasional nightmares, frequent nightmares may be a symptom of a larger problem such as post-traumatic stress disorder (ptsd) or sleep disorders. Treatments may include therapy and medication, depending on the underlying cause.
