Hypnosis and meditation do share some similarities but are actually distinct neural states.

We think of meditation as cardio for the mind, improving your overall mental health and well-being through mindfulness. Hypnosis is more like strength training, where you focus on retraining the thought patterns relating a single behavioral area.

Hypnosis doesn't involve being mindful of your thoughts like meditation, instead you become hyper-focused on what the hypnotist is saying, so its actually quite different.
