Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. Researchers, for ages, tried to study or analyze dreams. Majority of dreams are just some happenings during sleep and have no satisfactory explanations. Researches did not find any satisfactory explanation or analyze till now. Therefore, worrying about your dreams are not going to give you any solution. The best method to overcome your scary nightmares are to ignore them and get good sleep. To get good sleep- exercise, work hard, keep your mind off thoughts and be relaxed always. If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe the needed psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
