Occasional insomnia or excessive dreaming need not be of undue concern and can be left untreated as long as it does not interfere with daytime functioning.
If it occurs three or more times a week, it may be related to stress caused by life or work events, or may be caused by environmental factors in the sleep environment or by underlying depression, anxiety and certain physical illnesses or medications used.
Mild symptoms can be managed by adjusting the pace of work, regular rest and rest, appropriate outdoor activities or dietary adjustments, while more severe symptoms that affect daytime functioning and work and study should be promptly referred to a sleep clinic for professional guidance.
