If the nightmares are causing distress or disrupting your sleep, treatment may be recommended. Seeking a specialist, like a mental health professional or a sleep specialist, may also be suggested. No specific restrictions are mentioned, but keeping a sleep diary for two weeks before the appointment can provide valuable information for the doctor.
