Many people are wary of hypnosis because they are not educated on the topic. Hypnosis is a natural state and many people reach this state of consciousness every day without even realizing it. When you drive a car, you are in a light state of hypnosis. You are in control, you have an increased ability to concentrate, and you are operating on autopilot without really realizing it. A great deal of research has been conducted on the hypnotic state and various states of consciousness.
Your brain has four different brain wave states: beta, alpha, theta, and delta. While you are reading this article, you are in the state of beta. You are alert and able to concentrate on this article. The beta state is normal wakening state. Alpha state is a relaxed state. You are able to access creativity and visualization. Theta state is a deeper state of relaxation; this is a common state of hypnosis and meditation. Theta allows you to access memories. You experience theta as you fall asleep and wake up every day. Lastly is delta, which occurs while sleeping. Delta allows your body to heal.
