Neuro-Linguistic Hypnotherapy™ Has Been Successfully Used To Effectively Eliminate Fears and Phobias... Hypnosis is so effective in removing phobias, because it can find the cause of the fear and disconnect it from its stimulus. For example, a person with a fear of spiders developed the fear through a past experience with a spider. Through hypnosis, we can find the root cause of the problem and remove the fear from the memory. This also removes the fear from every other experience, including those in the future.
