What Is a Thought, Really? (And Why Won’t Mine Stop)
Something that comes up time and time again with my clients is overthinking. So I want to ask the question underneath the question: what exactly is a thought, and where does it come from?
Think about it (pun intended)… We can’t touch a thought until it’s made physical. And then, once it’s an object born from our creative mind-hand connection — a painting, a sentence, a building — is it still a thought? Maybe metaphorically. But actually?
Okay, nothing answered there. Just more questions.
Where Do Thoughts Even Come From?
Well, I know I can make a thought. If I think of myself eating a delicious yellow Zespri kiwi, I might go and do just that. So clearly, I can create a thought on purpose.
But what about the thoughts that appear from nowhere?
Did I choose those? Surely not — they just arrive, uninvited. Are those thoughts mine, or someone else’s? Ponderous.
Let’s assume, for now, that my brain isn’t an antenna and these aren’t the voices of my ancestors — that they come only from me.
The Density of Thought
These thought-forms — when are they most numerous? In my experience, they come thicker and faster during moments of heightened emotion. Someone triggers us and BOOM — here comes the rumination. Thoughts upon thoughts upon thoughts upon thoughts… and down the rabbit hole we go, spiralling, spiralling, spiralling. Until…
So surely emotion has something to do with thought, and thought has something to do with emotion.
What the Science Actually Says
Here’s where it gets interesting. You may have heard the popular claim — often attributed to neuroanatomist Dr. Jill Bolte Taylor — that a triggered emotion only lasts about 90 seconds in the body before the chemical wave passes. It’s a compelling idea, and it comes from a genuinely fascinating place: her own observations of her brain during a stroke. But it’s worth being honest here — this wasn’t a controlled study, and current research shows emotions don’t follow one neat, universal timer. Different emotions have different signatures; sadness lingers differently to fear, which lingers differently to anger.
So if the raw chemical wave of an emotion is short-lived, or at least shorter than it feels — why does anxiety hang around ALL DAY for some people? Interesting thought, right?
This is where the neuroscience of rumination gets useful. Researchers have identified a kind of feedback loop between three brain systems: the default mode network (the part of your brain that chatters away with self-referential thoughts when you’re not focused on anything external), the amygdala (which tags those thoughts with emotional weight), and the anterior cingulate cortex (which is meant to help you disengage attention, but in a rumination loop, doesn’t).
In plain language: your brain generates a thought, your amygdala stamps it “urgent” and floods it with feeling, and that feeling makes the thought feel more important, so your brain generates another one just like it. Round and round. That’s the neurological fingerprint of feeling “stuck.”
Of course, this is a simplified picture, with other factors at play — but it begs the question: what if we could interrupt the loop before it re-triggers the emotion that started the spiral in the first place?
It’s the Retriggering, Not the Feeling
Because that’s what’s actually happening. That crappy feeling isn’t sitting there constantly — it’s being retriggered, over and over, by our own thinking. It’s cyclical. Each ruminating thought reaches back into the amygdala and presses the button again.
I’ve learned — both personally and in the therapy room — that by resetting the nervous system and emptying out that overflowing vessel of stored, unresolved emotional charge from our past, we become able to feel our emotions from a place of balance and poise, rather than from a place of survival.
Like it should be. We’re human, after all. We’re built to feel things — not to be held hostage by the retelling of them.
Breaking the Loop
This is precisely the work I do with clients using clinical hypnotherapy, Timeline Therapy® and NLP: not silencing the mind, but clearing the old emotional charge that keeps refuelling the loop, and retraining the nervous system to recognise when it’s safe to stand down. When the vessel isn’t overflowing, a triggering moment stays a moment — not a spiral.
If overthinking, anxiety or rumination is a pattern you recognise in yourself, you don’t have to think your way out of it alone.
