Hypnotherapy and hypnosis makes use of abilities you already posses. This is because the hypnotic state, or 'trance state', that you enter into during a hypnotherapy session should already be familiar to you: have you ever driven a car somewhere you regularly visit and 'zoned out'? That zoned out state is similar to the state you enter into during hypnosis - which is primarily how online hypnotherapy is possible. Hypnosis is a natural approach that doesn't require a hypnotherapist to be present - as long as you can see and hear your hypnotherapist, you will be able to enjoy the same experience and benefits as a more traditional hypnotherapy session.
Many may find that the online hypnotherapy sessions suit them better: it still occurs in real time while offering you total privacy from the comfort of your own home!
