For someone scared of spiders, it may be that they are constantly scanning rooms before they enter them, jumping at any thing moving out the corner of their eye.  Even becoming frightened at a clump of grass on the carpet that might just be a spider.  

For someone who is afraid of heights it could affect their ability to travel, use bridges, enter high rise buildings and even as far as preventing them from climbing a ladder or going up stairs. 

For those afraid of things like needles and the doctor or dentist it could have a serious affect on their health, leaving them unable to sit in a dentists chair to receive urgent treatment.  Perhaps unable to receive vaccinations due to a huge fear of needles and experiencing things like high blood pressure and maybe even having a sense of panic waiting to see the doctor.

Interestingly the number one fear in the UK is public speaking, followed by a fear of deep water, with a fear of spiders coming in 3rd.  

However, you will be pleased to know that there are many different techniques you can use to interrupt the pattern of behaviour of a a fear or phobic response. By communicating with the unconscious mind we are able to re-educate it that it is possible to change that feeling or reaction and remain calm.

Regardless of what your fear is, rest assured that hypnosis and NLP can help you begin to understand and resolve the underlying issue.  Resulting in you being free from that fear and able to enjoy life in a calmer way
