Actually your Dr. may be right. Hypnophobia is the often irrational and excessive fear of sleep. It may result from a feeling of control loss, or anxiety over the loss of time that could be spent accomplishing tasks or maximizing leisure time instead of sleeping.
The symptoms may differ for different patients and may experience them in their own way.
Cognitive Therapy is a widely accepted form of treatment for most anxiety disorders. It is also thought to be particularly effective in combating disorders where the patient doesn’t actually fear a situation but, rather, fears what could result from being in said situation. The ultimate goal of cognitive therapy is to modify distorted thoughts or misconceptions associated with whatever is being feared; the theory is that modifying these thoughts will decrease anxiety and avoidance of certain situations. If you continue to have this problem you may want to consider therapy.
