It's actually quite the opposite. Hypnosis actually gives you control over the subconscious part of your mind that's normally out of reach.
Day-to-day, you control your actions through your consciousness. But beliefs locked in the subconscious have a tendency to create or release unwanted reactions like irrational fear, negative thoughts or annoying habits. They are often the root drivers of how we think, feel and act.
Hypnosis helps you speak directly to your subconscious, giving you the opportunity to change or improve some of the attitudes and beliefs embedded in your subconscious. You don’t lose control of yourself along the way. Instead, your attention is sharpened while you gain access to some of the automatic processes in your mind.
