De-Hypnotise Your Mind: The 'Leaves on a Stream' Technique for Overthinking and Anxiety

No time to read? Scroll below for a free guided recording and tips for daily mindfulness practice to unhook from overwhelming thoughts.

Have you ever found yourself so absorbed in a worry that the rest of the world fades away? It might start as something simple, but then it spirals; you follow the thoughts to their worst conclusion, and it starts to feel real. You feel the impact in your stomach or chest; your mind might be working so hard, focusing on worst-case scenarios, that you feel a headache coming on.

As a Cognitive Behavioural Hypnotherapist, the way I explain this feeling is that it is a form of negative self-hypnosis. You have become "fused" with your thoughts—treating them as absolute truths about yourself, others or the world. The images, feelings, emotions, conversations/arguments, the full-blown narrative that your mind creates are vivid and real. Just like with hypnosis when used in therapy, where we focus on positive changes and using your imagination to move towards the life you want to lead, this negative self-hypnosis leads you away from the life you want to lead.

Our minds, all minds - not just yours, mine too! and the person sitting next to you on the train, the person beeping their horn at you impatiently in their car, the kindest person you know who always seems calm and collected - have judgemental and uncomfortable thoughts "i'm not good enough", "I always get it wrong", "that was a stupid thing to say", "they don't like me". It's our minds trying to protect us from danger and keep us safe; they have evolved that way, and it has been very successful, given you are here reading this now - but our minds can't always get it right; it is only a prediction after all. And what is safer - to predict danger where there is none or to predict no danger where there is?

These judgemental thoughts, in and of themselves, aren't a good or bad thing; they are just part of being human. They only really become an issue if they get in the way of us leading the life we want to lead, when we spiral down with our thoughts and shy away from the things we really want to do: "I can't do this, i'll fail/that would be awful" or do things we really don't want to do: "I have to do this to be good / not to disappoint".

If we can't get rid of these thoughts, what can we do?

Mindfulness as De-Hypnosis

Mindfulness isn't about relaxation (but you might find it is relaxing - you might also find yourself tensing, or feeling you can't do it); it is the active practice of "unhooking" yourself from the story you are repeating by stepping back and realising that thoughts are just thoughts and that if left alone, they will come and go.

In Acceptance and Commitment Therapy (ACT), we use a powerful visualisation exercise called "Leaves on a Stream" to practice this skill. It helps us practice noticing thoughts, letting them just be and then coming and going - not to hold onto the thought or to try and push thoughts away. Acknowledge the thought, accept that it is there, make room for it, maybe even be curious about it: "Look, I'm having that thought", "that thought makes my stomach do flips", "there's a thought I get stuck on"

(Scroll down for the free 10-minute guided audio version). 

The Pink Elephant Paradox

When we get stuck on a thought, our instinct is often to push it away. But the act of pushing keeps that thought right at the centre of our mind.

Think of the classic example: "Don't think of a pink elephant." You likely just thought of a pink elephant. By trying to push the thought away, you are forced to interact with it.

The Leaves on a Stream exercise helps practice changing this dynamic. You aren't trying to stop your thoughts, but to change your relationship to them. You become the observer of the stream, rather than the leaves themselves.

How to Do the Exercise (The Basics)

🍃 The Practice: Leaves on a Stream

1. Set the Scene

Sit comfortably. You don't need to "go anywhere" mentally just imagine you are sitting by a gently flowing stream. Notice the water moving and imagine leaves floating on the surface.

2. Label & Place

As thoughts arise - whether they are words, images, or sounds - simply label them (e.g. "I'm having a thought about work"). Then imagine placing that thought gently onto a leaf.

3. Observe the Flow

Let the leaf float downstream. Don't try to push it to make it go faster, and don't try to stop it. Just watch it go.

4. The "Return" (Crucial)

If you find yourself getting "hooked" and forgetting the stream, simply notice it. That moment of noticing is the success. Gently place that "hooked" thought on a new leaf and return to the bank.

The Megatron Mishap: Why Perfection is a Myth

It is a common misconception that mindfulness should work the first time perfectly. In reality, your brain is creative, messy, and imaginative.

The first time I tried this exercise, my therapist mentioned the clinical term "meta-cognition." My relaxed brain misheard this as "Megatron" (the leader of the Transformers).

For the rest of the session, it wasn't leaves floating down a stream. It was a giant robot with a silver tray, walking into the water and physically carrying my thoughts away.

This happened the next two times I practised! But eventually, Megatron left me alone, and I learned to let thoughts go without his help.

The lesson? The "correct" way to do the exercise is simply to do it. If your stream looks like a robot, a bus, or clouds in the sky, that is fine. The goal isn't a perfect visualisation; it is the act of disengaging from the content of your thoughts.

And meta-cognition isn't a transformer but an academic way of saying "a thought about a thought..." for example rather than thinking "I'm having a bad day" you acknowledge that actually "I'm having the thought that... I'm having a bad day".

Troubleshooting: "Am I Doing It Wrong?"

If this feels clunky at first, you are not alone. Here are common hurdles and how to fix them:

1. "I Can't Visualise the Leaves"

• The Fix: You don't need a high-definition 4K mental image. This isn't an art project; it's a cognitive exercise.  If you can't "see" it, just acknowledge the concept of movement. You can even use sounds passing by or cars on a road.

  
  

2. "The Thoughts Are Coming Too Fast"

• The Fix: Don't try to catch every single one, that leads to more stress. If thoughts come in a rush, place them all on one giant leaf or a large branch and watch the whole bundle float away.

  
  

3. "The Thoughts Won't Move"

• The Fix: Don't push. Pushing is just another way of engaging.  If a leaf gets stuck on a rock, just watch it spin there. Acknowledge, "Here is a thought that is staying put."  That is still mindfulness.

  
  

4. "I Keep Getting Hooked/Distracted"

• The Fix: Celebrate that realisation!  The moment you realise you drifted off is the exact moment you succeeded. You just stepped out of the loop. Gently come back to the bank.

What next

📅 Your 5-Day "De-Hypnosis" Challenge

Building a new cognitive skill is like going to the gym. Try these micro-drills to build your "metacognitive muscle."

DAY 1: The Morning "Suggestion" Check

The Task: Before getting out of bed, notice your first thoughts (e.g., "Today will be hard").

The Goal: Label them ("I am having the suggestion that today will be hard") instead of buying into them.

DAY 2: The "Notification" Reset

The Task: For one hour, wait 10 seconds before checking any phone notification.

The Goal: Imagine the notification on a leaf floating by. Break the automatic loop of ping and respond.

DAY 3: The Sensory Anchor

The Task: During a mundane task (e.g., boiling the kettle), notice one thought, place it on the stream, then immediately focus on a physical sensation (warmth, feet on floor).

The Goal: Practice the change from internal noise to external reality.

DAY 4: The "Megatron" Audit

The Task: Take a sticky thought ("I'm not doing enough") and imagine it delivered by a ridiculous character (a robot or cartoon mouse).

The Goal: Realise the thought exists, but strip it of its authority using humour.

DAY 5: The Evening Stream Clean

The Task: Before sleep, visualise the "story of the day." Break it into leaves (Leaf 1: Traffic, Leaf 2: That Email).

The Goal: De-hypnotise yourself from the day's drama so you can rest.
