Hypnophobia refers to the condition of having an abnormal, extreme, and persistent fear of falling sleep (intentionally or otherwise).
Some texts define hypnophobia as an extreme fear of falling asleep or of being hypnotized.
More general information about extreme fears such as Hypnophobia:
Extreme fears (phobias) such as hypnophobia can lead to a variety of disturbing symptoms such as breathlessness, difficulty in thinking or speaking clearly, dizziness, a dry mouth, a fear of dying, a fear of "going mad" or losing control, a sense of feeling sick, the inability to concentate, inability to make decisions that are usually simple, nausea, palpitations, shaking, sweating profusely, or a severe anxiety attack. Not all sufferers are affected by all possible symptoms, and some individuals may also have other reactions.
Even though many adult sufferers of hypnophobia (and/or other fears/phobias) are aware that their fears are unreasonable, many still experience severe anxiety even when just thinking about the subject or situation they fear. However, phobias such as hypnophobia are known and are a relatively common form of anxiety disorder that may be treated conventionally using cognitive behavioral therapy including exposure and fear reduction techniques. Drugs may also be offered, typically anti-anxiety or anti-depressants - particularly during the early stages of treatment. Other forms of treatment offered may include hypnotherapy, Emotional Freedom Technique (EFT) or other similar therapies.
Note that the list of phobias in this section is not complete. There are very many more phobias, including some some obscure fears, that have specific names. See a list of phobias for more of these terms.
