Has anyone been hypnotised or know anything about it?

Be very careful if you let someone hypnotize you. The reason is that when a person is hypnotize their conscious mind is being relaxed and their subconscious mind is coming to the forefront. When this happens the person who is hypnotising you is touching your psyche(inner most being)and if they do not know what they are doing they can bring trouble to your psyche and in doing so bring problems to you in the short and long term. Please make sure that you know and trust whoever is hypnothising you and make sure they know what they are doing(see if they will give you references)
