If you have nightmares, try to understand the fears and the events in those dreams. They suggest that you might be holding on to be traumatic or guilt based conflicts. You may have a lot of powerful negative feelings that require reconciliation. If nightmares continue for an extended period of time, the individual should consider obtaining professional counseling services. Nightmares are a direct result of overwhelming feelings of fear and helplessness, or a result of an unprocessed traumatic experience. A nightmare is any dream that wakes you up because of its frightening and overwhelming images.
