Very disturbing dream, please help?

Nightmares can leave us too afraid to go back to sleep,.a nightmare is an expression of extreme anguish that can originate from either physiological or emotional cause, they represent our innermost fears. Distressed emotional states churning around in the mind. Violent dreams are often a subconscious bid to avenge or correct a sitution you have experienced in your waking life. If your body endures severe stress due to the intenseity of you nightmare it could cause you physical and/or mental problems. I would like to suggest that you seek a therapist for preventive maintence.
