Can you be hypnotised against your will? No, you cannot, and this is one of the most persistent myths I encounter in my work as a hypnotherapist. Hypnosis requires your consent and active cooperation from start to finish. It is not something done to you while you sit passively; it is something you take part in, and you can stop at any moment simply by choosing to open your eyes and disengage.
As a Quantum Journey Hypnotist and NLP Master Practitioner, I hear this worry from a fair number of new clients, usually shaped by films or television in which a hypnotist waves a pocket watch and the other person instantly loses control of their own mind. That image has done more to put people off genuinely helpful therapeutic work than almost anything else in the field, and it is worth taking apart properly.
Hypnosis Is a State of Cooperation, Not Control #
The NHS describes hypnotherapy as a therapy that uses hypnosis, a state of focused attention and deep relaxation, to help someone become more open to positive suggestion in pursuit of a change they themselves want to make. Note the word ‘want’. A hypnotherapist cannot install an intention that is not already at least partly present in you, and cannot override your own values, morals or sense of self-preservation. If a suggestion conflicts sharply with what you believe or want, your mind simply rejects it, often by your bringing yourself back to ordinary waking awareness.
Psychologist Irving Kirsch, known for his research on response expectancy theory, has argued persuasively that hypnotic response depends heavily on the expectations, beliefs and willingness of the person being hypnotised, not on some special power held by the hypnotist. In other words, you are always an active participant in the process, not a passive recipient of someone else’s influence.
You Stay Aware and in Control Throughout #
During a session, you remain conscious the entire time. You can hear everything I say, you can choose to accept or quietly dismiss any particular suggestion, and you are free to speak, shift position or stop altogether whenever you wish. This is a world away from the Hollywood idea of hypnosis as a switch that removes your free will. It is closer to a guided, focused form of relaxation in which you are working with me towards a change you have already decided you want, whether that is easing anxiety, breaking a habit or building confidence.
Clients are often surprised, the first time they experience hypnosis, by how ordinary and unremarkable it feels from the inside. There is no blackout, no sense of someone else taking the wheel. Most people describe it afterwards as similar to a calm, focused daydream, one in which they were choosing, throughout, how much attention to give each suggestion.
Stage Hypnosis and Why It Looks So Different #
Stage hypnosis complicates the picture, because it is genuinely dramatic to watch, and it can look as though the volunteers have lost all agency. What is actually happening is more nuanced: stage hypnotists select highly suggestible, socially uninhibited volunteers from a large audience, then rely on a mixture of genuine suggestibility, social pressure and showmanship to produce entertaining results. Volunteers are, at some level, willing participants who signed up to be part of the show, and the format rewards compliance and performance. None of this transfers to clinical hypnotherapy, where the entire purpose is calm, private, collaborative work rather than spectacle, and where a client who is unwilling or resistant to a particular suggestion simply will not respond to it.
Could Someone Be Hypnotised Without Realising It? #
Another version of this myth is the idea that a skilled hypnotist could induce trance covertly, without the other person’s knowledge, perhaps through a conversation or a few well-chosen words. This is not how hypnosis works. Formal hypnotic induction requires sustained focus and cooperation over a period of time, and a person who is not engaged with the process, or who is actively resisting it, does not enter a hypnotic state. Momentary persuasion techniques exist in sales and rhetoric, but they are a different phenomenon entirely from clinical hypnosis, and conflating the two is part of what keeps this myth alive.
Why This Distinction Matters Clinically #
Understanding that hypnosis is collaborative, not coercive, matters because it shapes how a session actually works. I cannot make a client stop smoking, resolve a phobia or feel calmer if they do not genuinely want that change and are not willing to engage with the process. My role is to guide, and the client’s role is to participate honestly, which is precisely why the first part of any session is spent understanding what someone actually wants, rather than assuming I can simply impose an outcome. Informed consent runs through the entire process, from explaining what a session involves beforehand to checking in throughout, and that is a professional and ethical requirement, not just a reassuring line.

Key Takeaways #
- Hypnosis requires your consent and active cooperation; it cannot be done to you against your will.
- Irving Kirsch’s research on response expectancy shows that your own beliefs and willingness shape how you respond to hypnosis, not power held by the hypnotist.
- You remain conscious and able to reject any suggestion or stop the session at any point.
- Stage hypnosis relies on willing, highly suggestible volunteers and showmanship, and is not representative of clinical hypnotherapy.
- Covert or accidental hypnosis is not possible; genuine induction requires sustained focus and cooperation.
- Informed consent is central to ethical hypnotherapy practice throughout every session.
