10 Common Myths About Hypnotherapy (and What's Actually True)

The pocket watch swings. A confident stranger clicks his fingers. A volunteer, utterly convinced she's a chicken, starts clucking on cue. That's what most Australians picture the moment they hear the word "hypnosis". But it's almost nothing like what happens in a real hypnotherapy session.

These images stick around because stage hypnosis, old thrillers and decades of cultural shorthand are entertaining precisely because they misrepresent what hypnosis actually is. The problem is that when someone considers hypnotherapy for a genuine reason, such as anxiety, chronic pain, or quitting smoking, these hypnotherapy myths get in the way of a treatment that could help them.

This article walks through the ten most persistent hypnotherapy myths we hear from prospective clients, prospective students and the general public. For each one, we explain where it comes from, why it's wrong, and what the evidence and clinical experience actually show. 

The 10 Myths About Hypnotherapy

Myth 1: You can be made to do anything against your will

This one comes from stage hypnotism, where volunteers appear to do outlandish things on command, plus decades of thriller films and crime dramas that depict hypnosis as mind control.

The truth: A person in hypnosis stays fully aware and in control of their actions. Hypnosis cannot compel anyone to act against their values, beliefs or safety. If a suggestion doesn't sit right, the person simply won't act on it and can end the session at any time.

Clinical training across Australia's peak bodies, including the Hypnotherapy Council of Australia (HCA) and the Australian Hypnotherapists' Association (AHA), teaches that hypnosis works through a client's willing engagement with suggestion, not through control. The "chicken clucking" on stage involves volunteers who signed up to entertain and were selected for their high suggestibility and willingness to perform. They aren't compelled; they're participating in a social performance. A clinical hypnotherapy session is a completely different contract: you agreed to work on your anxiety, not to bark like a dog.

Myth 2: Only weak-minded people can be hypnotised

If hypnosis is popularly framed as a kind of mind control, it follows that someone must be "susceptible", which culturally gets read as weakness. It's also a handy way for sceptics to dismiss the practice.

The truth: People who are intelligent, imaginative and able to concentrate tend to make the best hypnotic subjects. Can weak-minded people be hypnotised, or can weak-minded people be hypnotised more easily than everyone else? No, hypnotisability isn't about mental strength or weakness at all. It's a collaborative process that works best with clients who can focus attention, follow guidance and use their imagination.

The Stanford Hypnotic Susceptibility Scales,, developed by Ernest Hilgard and Andre Weitzenhoffer, have been used for decades to measure hypnotisability, and studies using them consistently link higher susceptibility to traits such as absorption capacity, imagination, and openness to experience, not to any cognitive deficit. 

Myth 3: You can get stuck in hypnosis

Early 20th-century thrillers ran with this idea, and it persists because hypnosis resembles sleep, prompting viewers to wonder what happens if someone doesn't "wake up."

The truth: No one has ever remained in a hypnotic state indefinitely. So, can you get stuck in hypnosis? No, it's a naturally entered state of focused attention that dissipates on its own if it isn't maintained, much like drifting off during a dull meeting. If a session were interrupted abruptly, the person would either fall asleep normally and wake up, or spontaneously return to ordinary awareness within moments.

In more than two centuries of documented hypnotherapy practice, there's no credible case of anyone remaining in a hypnotic state after their session ended. Hypnosis is maintained by focused attention; when that attention releases, as it always does, the state releases with it. The myth may partly stem from the older habit of hypnotists using dramatic "you will wake feeling refreshed" endings, which imply the person might not wake otherwise. 

Myth 4: Hypnosis is sleep or unconsciousness

The word itself comes from Hypnos, the Greek god of sleep, and the still body and closed eyes of a hypnotised person reinforce the visual.

The truth: Hypnosis is not sleep. EEG and fMRI research shows the hypnotic state produces brain activity distinct from both ordinary waking consciousness and any stage of sleep. In hypnosis, a person is awake, aware and often more focused than usual.

David Spiegel's team at Stanford Medicine has used fMRI to identify altered activity across the brain's attention and self-referential networks during hypnosis, findings consistent with EEG research showing distinctive theta and alpha activity that doesn't match sleep patterns. Many clients are surprised after their first session to realise they heard everything the practitioner said and could have opened their eyes at any point. People often ask us can you remember what happened during hypnosis once it's over, and for most clients, the answer is yes. They recall the session in detail, right down to specific phrases their hypnotherapist used. 

Myth 5: You have to be gullible to be hypnotised

A close cousin of the "weak-minded" myth. If hypnosis is about accepting suggestions, the logic goes, only credulous people would fall for it.

The truth: Hypnotic susceptibility correlates with the ability to focus attention and use imagination, not with gullibility or credulity in everyday life. Critical thinkers often make excellent hypnotic subjects precisely because they can engage fully with the state once they've chosen to.

The Stanford Hypnotic Susceptibility Scales and the research built on them find no correlation between hypnotisability and general credulity or a lack of critical thinking. If anything, highly hypnotisable people tend to be cognitively sophisticated rather than the opposite. The confusion arises because "suggestibility" is a specific technical term in hypnosis research rather than a synonym for gullibility. A surgeon and a physicist can both be highly hypnotisable; a very sceptical person on a stage might not respond at all.

Myth 6: Hypnotherapy is the same as stage hypnosis

For most people, their only real exposure to hypnosis is entertainment, and this becomes the mental template for the whole field.

The truth: Stage hypnosis and clinical hypnotherapy share some techniques but have almost nothing else in common. Stage hypnosis is entertainment, performed with pre-selected, highly suggestible volunteers who agreed to perform in front of an audience whose expectations shape the entire event. Clinical hypnotherapy is therapy: a trained practitioner working confidentially with an individual client, using the hypnotic state to support goals the client has chosen for themselves.

Practitioners trained through Australia's peak bodies study assessment, ethics, scope of practice and specific clinical techniques. If you're curious about the more collaborative end of clinical technique, our guide to what Ericksonian hypnosis is explains one of the approaches taught at diploma level.

Myth 7: Hypnotherapy isn't scientifically supported

Hypnosis has a long association with spiritualism and showmanship, which has left plenty of people assuming it lacks a research base.

The truth: Hypnotherapy actually has one of the more substantial evidence bases in complementary and integrative medicine, particularly for chronic pain, irritable bowel syndrome, procedural anxiety and smoking cessation. Neuroimaging research from institutions including Stanford Medicine has documented measurable, reproducible brain changes during hypnotic states.

The UK's National Institute for Health and Care Excellence (NICE) recommends gut-directed hypnotherapy for irritable bowel syndrome that hasn't responded adequately to other treatments; a recommendation echoed by gastroenterology bodies in Europe and North America. Randomised controlled trials on hypnotic analgesia for fibromyalgia and procedural pain have shown outcomes comparable to, and in some cases better than, standard care, and the evidence base for hypnotherapy for chronic pain is one of the strongest in the field. The evidence base varies by condition: it's strongest for pain, IBS and smoking cessation, and considerably thinner for conditions like depression, which is why hypnotherapy for depression is generally used only as a complementary support alongside primary mental health care, not as a standalone treatment, and sits outside most hypnotherapists' scope of practice as a first-line intervention.

Myth 8: A hypnotherapist can reveal your secrets or read your mind

Films and thrillers love the idea of hypnosis as a truth serum, a process where the subject reveals everything against their will.

The truth: A person in hypnosis retains their normal ability to withhold information. Anything said in a session is voluntary, and clients often notice exactly when they've chosen not to share something. So can hypnosis reveal secrets a person doesn't want to give up? No. A hypnotherapist can't extract information you're not willing to disclose, and hypnosis doesn't reliably improve memory accuracy either. If anything, it can increase someone's confidence in an inaccurate recollection, which is a major reason courts treat hypnotically influenced testimony with caution.

Some people avoid hypnotherapy, worried a practitioner could reveal secrets they'd rather keep private. In Australia, the NSW Office of the Director of Public Prosecutions' guidelines on evidence derived from hypnosis set out strict rules governing when such evidence can be used at all, following cases including R v Jenkyns (1993) 32 NSWLR 712, which generally restrict admissible evidence to what a witness could already recall before the procedure took place. A clinical hypnotherapist working ethically will never attempt to use hypnosis to extract information a client hasn't chosen to share, and confidentiality obligations under professional codes of ethics apply just as they would in any other therapeutic setting.

Myth 9: If hypnosis worked, everyone would use it for everything

A version of "if it were that good, it would be mainstream". Understandable scepticism, but it misreads how healthcare systems actually adopt new therapies.

The truth: Hypnotherapy is used more widely than most people realise, including in mainstream medical settings for procedural pain, cancer supportive care and burn treatment. Its integration into general healthcare has been slower than the evidence would justify, partly because of its historical association with stage hypnosis, and partly because it remains a self-regulated profession in Australia rather than one registered under AHPRA.

At the University Hospital of Liège in Belgium, anaesthesiology teams led by Professor Marie-Elisabeth Faymonville have performed thousands of surgical procedures using hypnosedation (hypnosis combined with light sedation and local anaesthetic) as a documented alternative to general anaesthesia for suitable patients. In the United States, psychologist David Patterson built decades of clinical work using hypnosis for burn wound care at Harborview Medical Center in Seattle. The "if it worked, we'd all be using it" argument doesn't hold up against a reality in which healthcare adoption is shaped as much by regulation, training pipelines, and professional politics as by evidence.

Myth 10: Hypnotherapy is dangerous

This one draws on the "you can be made to do anything" myth, a cultural association with the occult, and reasonable caution around anything involving an altered state of consciousness.

The truth: Hypnotherapy delivered by a qualified, peak-body-registered practitioner is generally very safe. It's a non-invasive, drug-free intervention where the client remains conscious and in control throughout. That said, it isn't appropriate for everyone or every condition. Trained practitioners learn to recognise when it's not the right approach, including active psychosis, certain dissociative presentations, and situations requiring concurrent psychiatric care.

Adverse events in hypnotherapy are rare and generally involve emotional processing of difficult material, which is a normal part of therapeutic work, rather than a risk specific to hypnosis. The greater risk comes from unqualified practitioners working outside their scope of practice, which is exactly why registration with a peak body like the HCA, AHA or the Australian Society of Clinical Hypnotherapists (ASCH) matters. Hypnotherapy has been used safely by trained practitioners for over 250 years, and in mainstream medical settings for decades, including as one of the more common referrals for hypnotherapy for stress management, where the goal is simply a calmer nervous system, not anything more dramatic.

Why These Hypnotherapy Myths Persist 

There's a fairly obvious cultural pipeline feeding these hypnotherapy myths: stage shows, thriller films, novels and decades of television all depicting hypnosis as mind control or party trick. For over a century, hypnosis has existed at the intersection of stage entertainment, spiritualism and legitimate clinical work, which has made it genuinely hard for the public to sort fact from fiction.

The real cost is that people who could benefit from hypnotherapy for genuine reasons sometimes avoid it because they're worried they'll end up clucking like a chicken or losing control of their own mind. Separating hypnosis myths and facts isn't just an academic exercise; it's what stands between someone and a treatment that might actually help them.

Good clinical training is a big part of clearing this up. A well-trained hypnotherapist is precisely the person who can separate fact from fiction, because they understand both the technique and the theatre that surrounds it.

What Proper Hypnotherapy Training Teaches About All of This

A well-trained hypnotherapist can explain to a nervous first-time client, in plain language, exactly what will and won't happen in a session, because they understand the neuroscience, the history and the actual mechanics of hypnosis. Every myth in this article is something a diploma-qualified hypnotherapist has learned to address specifically, because these are the exact questions real clients ask.

The training pathway builds this understanding in stages. Certificate-level training establishes core techniques and introduces the history of hypnosis, including the origins of these myths. Diploma-level training builds the clinical, ethical and communication skills needed to work with real clients, including how to respond to their preconceptions before a session even begins. A hypnotherapy advanced diploma or specialty modules go further, developing the depth needed to teach, supervise and specialise.

If you're considering hypnotherapy training yourself, the Certificate in Clinical Hypnotherapy is the accredited starting point, with the Diploma of Clinical Hypnotherapy and hypnotherapy advanced diploma building on it.

Where the Hypnotherapy Myths Leave Us

Hypnotherapy is neither the mind-control fantasy of thrillers nor the mystical practice sceptics dismiss it as. It's a well-studied clinical tool with real applications, real limitations and real evidence, used by trained practitioners to help people with genuine problems. If these myths about hypnotherapy were the only thing keeping you from considering hypnotherapy for a real reason, we hope this has cleared a little space to reconsider.
