Many good books that can help you get started interpreting your dreams. See the ASD Book Suggestion List. Recurrent dreams, which can continue for years, may be treated as any other dream. That is, one may look for parallels between the dream and the thoughts, feelings, behavior, and motives of the dreamer. Understanding the meaning of the recurrent dream sometimes can help the dreamer resolve an issue that he or she has been struggling with for years.
Nightmares are very common among children and fairly common among adults.
Often nightmares are caused by stress, traumatic experiences, emotional difficulties, drugs or medication, or illness. However, some people have frequent nightmares that seem unrelated to their waking lives. Recent studies suggest that these people tend to be more open, sensitive, trusting, and emotional than average. No, these beliefs are not true. You can explore the meaning of these kinds of images just as you would explore any others that might occur in your dreams.
