What is hypnotherapy? A complete, honest guide to hypnosis and how it works

Hypnosis & the mind 12 min read By Undermind · Breukelen

Hypnosis is one of the most misunderstood words in the language. Stage shows made it look like mind control; films made it look like sleep. The reality is quieter, more grounded, and far more useful — a recognised therapeutic tool with two centuries of clinical history and a growing body of evidence behind it.

This guide explains, honestly, what hypnotherapy actually is, how it works, what it helps with, what the research really shows, and what to expect from a session in my practice near Utrecht. No mysticism, no inflated promises — just a clear picture.

Quick answers

What is hypnotherapy?
A guided therapeutic use of hypnosis — a focused, relaxed state — to work with a real issue at its root. See the full Method.
Is it mind control?
No. You stay fully aware and in control throughout, and remember the session. You can stop at any moment.
What does it help with?
Anxiety, stress and burnout, trauma, confidence, and habits such as smoking or emotional eating.
How many sessions?
Usually between one and four. Pricing is plain and per-session — see Pricing.
Is there evidence?
Yes — randomised trials and meta-analyses, strongest for pain, anxiety and procedures. Honest caveats below.

There's a full FAQ covering safety, the session, money and practical detail.

What hypnosis actually is

Hypnosis is a state of focused attention, deep physical relaxation, and heightened response to suggestion. It is not sleep, and it is not unconsciousness — if anything it's the opposite: your attention narrows and sharpens while everything around it fades.

You already enter this state several times a day without noticing — drifting off to sleep, driving on autopilot, lost in a film or a song. In each, your body settles and your critical, analysing mind steps back. That is the doorway hypnotherapy uses, on purpose and with direction. Functional brain imaging has shown measurable changes in brain activity during hypnosis, which is part of why it's taken seriously as a genuine physiological state rather than a trick.

Hypnotherapy isn't performance. It's deep listening — using a natural state to reach the part of you that already knows where a problem began.

How it works — and an honest caveat

Most problems people bring aren't problems of information. You usually already know the fear is irrational or the habit hurts you. Knowing it changes little, because the pattern doesn't live in the thinking mind — it lives somewhere older and quieter. Hypnotherapy reaches that level directly: in the focused, relaxed state it becomes possible to find where a pattern began and work with it there, rather than managing the symptom on the surface.

The honest part: this is a real, measurable tool — and it is not magic, and not a guaranteed cure. Response varies between people, and no responsible practitioner promises a fixed outcome. What I can promise is an honest assessment of whether it's likely to help you.

Dispelling the myths

The myth

You're unconscious and under someone else's control.

The reality

You're awake and aware. It's focused attention — you can speak, decide and stop anytime.

The myth

You can be made to act against your will.

The reality

You cannot be made to act against your values. You remain the author of every choice.

The myth

You won't remember anything.

The reality

You remember the session. It often brings buried material into clearer view.

The myth

It's an instant, one-size-fits-all cure.

The reality

It's structured work tailored to you, usually over one to four sessions — not a stage trick.

Anxiety, stress and burnout

Rates of anxiety and burnout are high, and talk therapy often addresses the symptoms without resolving the underlying trigger. Hypnotherapy works differently: it guides you, from a place of safety, to the origin of the distress, so the triggering experience can be reprocessed and its emotional charge reduced. Many people report a meaningful drop in day-to-day tension as a result.

From the research
A meta-analysis of randomised controlled trials found that around 64% of patients improved after hypnosis, compared with about 37% of those who received no treatment.

Habits and confidence

Much of our behaviour runs on subconscious patterns formed long ago, which is why willpower alone so often fails — the conscious effort is outmatched by deeper programming. A habit is usually a solution to an unnamed problem. When we work with what the habit is really doing for you, letting go of it becomes far easier — and as the old pattern loosens, confidence tends to return on its own.

The OMNI Advanced approach

Not all hypnotherapy is equal. I work within the OMNI framework — an internationally recognised standard in clinical hypnotherapy, founded in 1979 by Gerald Kein on the work of Dave Elman, and taught to a single standard in more than twenty countries. Its core principle is simple: every symptom has a cause; remove the cause and the system returns to health.

The OMNI process was also the first hypnosis process in the world to gain ISO 9001 certification (2015) — independent proof that the work is structured, documented and repeatable, not improvised. For you, that means predictability and efficiency: reaching the cause quickly and resolving it in as few sessions as possible.

How a session works with me

It begins with a free consultation to understand your goal and history, and to check we're a fit — you can book that first conversation here. A full session then runs two to three hours — long enough to reach the cause and resolve it in one sitting, rather than stopping mid-process because a clock says so. You stay conscious and able to speak throughout. You can read more about who guides you on the About page.

In a 2019 meta-analysis, the average person receiving hypnosis for anxiety improved more than about 84% of those in the control conditions.

Sessions near Utrecht — in Breukelen

In-person sessions take place in my practice in Breukelen, a short distance from Utrecht — a quiet space away from daily pressure, which makes it easier to settle into the work. The free first consultation can be online or by phone, so you don't need to travel for that. Sessions are held in English or Polish, whichever lets you speak most freely.

The bottom line

Hypnotherapy is neither magic nor theatre. It is the deliberate, skilled use of a natural state of mind to reach a problem at its root — backed by two centuries of refinement and a real evidence base, and held to a recognised standard through the OMNI method. Applied well, by someone honest, it can shift something that years of thinking about it never touched.

Frequently asked questions

Is hypnotherapy scientifically supported?

Yes. It's supported by randomised controlled trials and meta-analyses, with the strongest evidence for pain, medical procedures and anxiety. Study quality varies and it isn't a cure-all — but it is a genuine, measurable tool.

Will I lose control of my mind?

No. There's no mind control and no loss of consciousness. You stay aware of your surroundings and will never act against your values.

How does it find the root of anxiety?

In the relaxed, focused state the subconscious is more accessible, which lets you safely revisit and reprocess the events that first triggered the anxiety — reducing their charge.

Can it help with burnout and stress?

Often, yes. It works with the nervous-system response underneath burnout, helping shift how the body reacts to stress and supporting genuine recovery.

How many sessions will I need?

Usually one to four, depending on the issue. Some people shift a great deal in a single session; others need a short series. We review after the first.

What's different about OMNI hypnotherapy?

OMNI is an advanced, internationally recognised method with a strict, systematic framework — designed to reach and resolve the root cause rather than manage symptoms.

Is it safe for everyone?

It's very safe for most people, but it isn't suitable for certain serious psychiatric conditions, or only alongside medical care. The free consultation is there partly to check it's right for you.
