The more common phobias include a fear of spiders, flying, heights, blood, dentists, being sick, or enclosed spaces. We are aware of over three hundred phobias, many caused by unthinking actions or words experienced during childhood. These can cause severe emotional and stressful problems later in life, causing much suffering for years. Hypnotherapy is almost certainly the easiest, safest, quickest and most effective way of dealing with phobias.
