Daydreaming: The Trance You Fall Into Without Being Asked
The sentence I hear most often, usually within the first ten minutes, is I don't think I can be hypnotised. I've stopped arguing with it and ask about the commute instead. Within a minute the person is describing the stretch of motorway they cannot remember driving, or the meeting where they surfaced to hear their own name and had no idea what had been said. They tell me this as small talk. They don't hear themselves describing the thing they've just declared themselves incapable of.
Everybody does it, several times a day, without permission being asked or given. Attention detaches from the room and goes somewhere else. That's daydreaming, and it's the cheapest available proof that trance is ordinary equipment rather than a trick performed on the unusually weak-minded.
What daydreaming actually is
Daydreaming is a spontaneous shift of attention away from the immediate environment and towards internally generated content — scenes, conversations, rehearsals, memories, plans — that arrives largely without deliberate effort and typically involves a loosened sense of the actual surroundings and a distorted sense of how much time has passed. It happens in ordinary wakefulness, several times an hour in most people, and it usually ends without anyone noticing where the seam was.
Two terms sit near it and get muddled. Mind wandering is the broader research label, covering any drift of attention away from the task at hand, including the dull, unstructured, going-nowhere kind. Daydreaming implies content — something is being built in there, with characters or scenery or a version of you saying the thing you should have said in 2019. Every daydream is mind wandering. Not every wandering mind is producing anything worth watching.
The mechanics, described plainly
Take the state apart and you get four components. They are the same four I work with professionally, which is the point of this article.
Attention turns inward. The room keeps arriving at your eyes and ears, and you stop processing most of it. Researchers call this perceptual decoupling — the input still comes in, the machinery that usually makes something of it has gone elsewhere. This is why you can read a page and reach the bottom having taken in nothing. The eyes tracked. The rest didn't.
Reality-checking goes quiet. Inside a daydream you rarely stop to ask whether any of this is happening. There's no verdict, no fact-check, no hold on. The content is simply accepted while it runs, and only on the way out do you file it as imagination. That drop in critical filtering is, as far as I can tell from the inside and the literature can tell from the outside, the feature suggestion leans on hardest, in a daydream and in a session.
The images build themselves. You didn't decide on the staircase, the argument, the face. It assembled. That absence of a felt author is what people report after a good induction — I wasn't doing that, it just happened — and it's also why they conclude nothing happened, since in their model, real experiences arrive with the sensation of having chosen them.
Time stops being reliable. Ninety seconds reads as ten minutes, or twenty minutes vanish into what felt like a thought and a half. Time distortion is one of the most consistent things people report coming out of trance, and it's free with every daydream.
Line those four up and you have a description of trance that would satisfy most people who study it. Nobody induced it. It arrived on the bus.
The clearest everyday version is the one behind the wheel, which has its own name and its own article — highway hypnosis — and the useful thing about it is that competent motor behaviour continued throughout. You steered. You braked. Somebody was minding the shop. The part of you that narrates the day had clocked off, which is roughly what people are gesturing at when they say subconscious mind, and it's why "under" has never meant "unconscious".

See the bookThe default mode network, without the incense
You'll find the default mode network cited in every article about daydreaming, usually with the tone of a reveal. So let me say what it is and what it isn't.
It's a set of brain regions — medial prefrontal areas, the posterior cingulate and precuneus, parts of the lateral parietal cortex — that tend to become more active together when a person isn't engaged in a demanding external task, and to quieten down when one arrives. Marcus Raichle's group described and named this pattern, and the way they found it is the best part of the story: the network turned up in the baseline condition, the boring interval that imaging studies were subtracting away as noise. The resting brain, it turned out, was not resting. It was expensive, coordinated and busy.
Now the corrections. The default mode network is not a daydream organ. It's a statistical pattern of correlated activity across regions that each do other things in other contexts, and calling it the imagination centre is the neuroscience equivalent of calling the M25 the going-to-work road. It turns up in autobiographical memory, in thinking about other people's minds, in imagining future situations — activities that all involve constructing something not present, which is presumably why it shows up when you drift. Nor does it switch on and off like a lamp; what changes is how strongly it's coupled to the networks handling deliberate control.
That coupling is the bit that matters for my line of work. The imaging literature on hypnosis returns again and again to altered coupling between executive control regions and the default mode network. I would like to tell you it is settled. It is not: when someone pooled the studies looking for exactly that signature, it did not come out cleanly, and the field's own reviews call the results inconsistent. A recurring theme, not a result you can bank — which is the same caution I applied at length in is hypnosis real. No scan certifies an individual as hypnotised, and no scan certifies one as daydreaming either. What the imaging supports is narrower and enough: these are related configurations of the same brain, not one real state and one imaginary one.
The honest mess in the research
Here's where I have to hand you two findings that don't sit comfortably together, because the alternative is to pick the one that suits my argument.
Killingsworth and Gilbert ran a large smartphone-sampling study — pinging people through the day, asking what they were doing, whether their mind was on it, and how they felt — and the headline that came out of it was that a wandering mind is an unhappy mind. People reported lower mood while off-task than on-task, including during activities they didn't much enjoy. It's a genuinely uncomfortable result, and the association itself has held up.
Against that: spontaneous thought is repeatedly associated with creative incubation — the solution that arrives in the shower rather than at the desk — and with prospection, the ordinary and rather important business of simulating your own future so you can prepare for it. Rehearsing a conversation before you have it is a daydream doing useful work.
The reconciliation people usually reach for is that content matters more than the drifting itself. Wandering into rumination, into the same grievance for the ninth time, tracks badly. Wandering into something absorbing or forward-looking doesn't, and may track the other way. What has not held up is the direction. Killingsworth and Gilbert ran time-lag analyses and concluded the drifting came first; later groups running the same design got the opposite, mood first and drift after, and one found that genuinely interesting off-task thought lifted mood rather than lowering it. Sampling studies show you what travels with what, and the arrow is still in the air. The evidence here is mixed, and the mixture is the finding.
When daydreaming stops being harmless
There's a version of this that costs people years, and it deserves careful language.
Eli Somer coined the term maladaptive daydreaming in the early 2000s, from clinical observation of patients whose inner lives had grown past anything the word "daydream" prepares you for. The picture people describe is consistent: hours a day, sometimes most of the waking day. Elaborate, serialised inner worlds with recurring characters and continuing storylines, developed over years. Music as the reliable trigger — a particular playlist, the same tracks, run and re-run. Accompanying movement: pacing a room, rocking, gesturing, whispering, facial expression tracking the scene. A pull towards it that people describe in the vocabulary of craving. And real cost — sleep, work, study, relationships, the shame of a secret that sounds absurd to explain.
The people who live with it know it's fantasy. That's not the problem, and it distinguishes this from anything psychotic. The problem is that they can't get out, and would often rather be in there than here.
Now the part that matters and that most articles blur. Maladaptive daydreaming is not a recognised diagnosis in DSM-5 or ICD-11. There are no officially recognised diagnostic criteria and no formal diagnosis to receive. Researchers have proposed criteria and validated a screening questionnaire — the Maladaptive Daydreaming Scale — but a research instrument is not a diagnosis. That is a statement about the state of the classification systems, not a verdict on whether people are suffering — they plainly are, in numbers large enough that researchers have spent two decades characterising it, and the pattern of accompanying difficulties looks a good deal like that of conditions already in the books. Relationships with ADHD, anxiety, dissociation and the aftermath of trauma are under active investigation and are not settled.
What follows practically: if this is your life, the useful move is a clinician who can look at the whole picture — the daydreaming, the attention, the anxiety, whatever sits underneath — rather than a self-scored quiz on the internet. I'm not going to hand you a score and call it an answer; the researchers have a scale, and it belongs in a consulting room rather than a comments section. And to be blunt about my own field: this is not something to bring to a hypnotist, mine or anyone else's.
What I actually do differently
So if daydreaming is trance, and everyone's already doing it, what's left for me?
Direction.
A daydream runs itself. Nobody chose the destination, nobody's holding the route, and it ends when something in the room gets loud enough. That's the whole difference — not depth, not intensity, not some rarefied state you have to be gifted to reach. Every ingredient is already installed in you and running unsupervised. The same holds at the edge of sleep, where the slide inward has a name of its own — hypnagogia — and where anyone stubborn enough to keep one thread of attention awake can turn it into lucid dreaming.
What changes when someone competent is involved is that the state acquires a direction and a person keeping it: a destination agreed in advance by people who talked about it first, a voice setting the pace and noticing what your face is doing, and something at the far end that closes properly instead of dissolving when your phone goes. That's true of guided imagery in a physiotherapy waiting room, it's true of the self-hypnosis techniques you can run on yourself, and it's true of the work I do, which is the same mechanism aimed somewhere considerably more specific, by agreement, between adults.
You already have the state. You fell into it twice while reading this. The only question worth asking is whether anyone's steering.
FAQ
Is daydreaming the same as hypnosis? They share the core mechanics — inward-turned attention, reduced critical filtering, imagery arriving without effort, distorted time — which is why daydreaming is such good evidence that trance is ordinary. The difference is direction and intent. A daydream starts by itself, goes wherever it goes and stops when something interrupts it. Hypnosis is that state entered deliberately, with a destination and someone holding it.
Is daydreaming bad for you? The research points both ways and that's the honest answer. Smartphone-sampling work has linked off-task attention with lower mood in the moment, while other lines of research connect spontaneous thought to creative problem-solving and to planning for the future. Content and direction seem to matter more than the drifting itself, and the causal direction is unresolved — low mood may set the mind wandering as readily as the reverse.
Is maladaptive daydreaming a real diagnosis? It is a real, well-described phenomenon and not a recognised diagnosis. Eli Somer named it in the early 2000s, and the pattern reported since is consistent: hours of elaborate inner narrative, usually with music and accompanying movement, with genuine distress and functional cost. But it appears in neither DSM-5 nor ICD-11, there are no agreed criteria, and no one can formally diagnose it. Anyone losing large parts of their life to it should be talking to a qualified clinician rather than an online checklist.
What is the default mode network in plain terms? A group of brain regions that reliably become more active together when attention isn't tied up in a demanding external task, and quieten when one arrives. It was found in the intervals that imaging studies were discarding as baseline. It is a pattern of coordinated activity, not a dedicated daydreaming organ, and the same regions do other jobs in other contexts. What shifts during trance and during mind wandering is largely how it couples with the networks handling deliberate control.
