Nightmare disorder: Please see a psychiatrist who also specializes in sleep disorders if you can. It sounds like you have a nightmare disorder but you could haveptsd. Treatment is usually prazosin to stop the nightmares. If you have post traumatic stress disorder the psychiatrist will also recommends psychotherapy. Most people with pure nightmare disorder do not require psychotherapy.

Nightmare: Confide in someone close to see if you can identify the origin of your dreams. If you are waking up troubled you are likely trying to work something out in your sleep that you are not dealing with during the day. If the nightmares persist consult a mental health professional who can help you uncover the origin of the dreams and help you deal effectively with is troubling you. Best.

One idea: I used to take amantadine in the winter for influenza prophylaxis. It's famous for producing truly scary dreams. I actually came to enjoy them. If you're perhaps taking some medication, they may be a side-effect. It's also important not to be superstitious about these things -- this leads nowhere. Cherish your life and if you need to, talk with someone wise and good.
