Why do I feel like something bad is about to happen?
Nothing’s actually wrong. Your diary is clear, nobody’s upset with you, there’s no deadline you’ve forgotten. And yet, there’s a low, persistent hum of dread sitting somewhere in your chest, as if you’re bracing for news that hasn’t arrived yet.
If you’ve ever felt like you’re waiting for impact with no idea what the impact even is, this feeling has a name; anticipatory anxiety, and a clear story behind it that has more to do with your nervous system’s settings than with anything actually happening around you right now.
What’s actually happening in your body
Psychiatrist and researcher Stephen Porges’ work on the autonomic nervous system describes a process he calls neuroception: an unconscious, constant scan the body runs for cues of safety or danger, entirely beneath conscious awareness. Most of the time, this happens quietly in the background (like a computer anti-virus software), calibrating your physiological state to match your actual surroundings.
But neuroception can be calibrated incorrectly, particularly after periods of chronic stress, unpredictability, or earlier experiences where calm turned out not to be reliable. When that happens, the body can register low-level danger signals in objectively safe conditions: a quiet evening, an empty diary, a fine day, simply because ‘calm’ itself has, at some point, stopped being a trustworthy signal. The dread you’re feeling isn’t really about anything in front of you. It’s a body that’s learned to treat stillness with suspicion.
Why ‘nothing is wrong’ doesn’t reassure the body
This is one of the more frustrating features of anticipatory anxiety: knowing, intellectually, that nothing is actually wrong rarely switches it off. that’s because this is a bottom-up problem (meaning it starts in the body, not the mind) rather than a top-down one. Psychiatrist Bessel van Der Kolk’s research on trauma and the body describes how physiological states, once established, often don’t respond well to reasoning alone. Further, Kotler et al.’s (2026) research found that after trauma, the brain often loses the ability to switch fluidly between semi-stable states (i.e. the brain is such less able to consider other possibilities for a racing heart, for example, after trauma. It must be danger).
This is also connected to interoception, the felt sense of what’s happening inside your own body. Research by neuroscientist Bud Craig and others has shown that people vary considerably in how strongly they register internal bodily signals, and for some, a slightly activated nervous system simply reads as ‘something is wrong’, without any further information attached, because the felt sense of unease arrives well before any thought does.
The ‘waiting for the other shoe to drop’ pattern
This pattern often has a clear origin. Growing up in an environment where calm periods didn’t reliably predict safety, where conflict, unpredictability, or chronic stress could resurface without much warning, teaches the nervous system that hyper vigilance is the sensible response. At the time, it almost certainly was. The trouble is that the nervous system’s danger setting doesn’t automatically reset once the environment changes. It keeps scanning for the same warning signs, long after they’ve stopped being relevant.
This is closely related to the background anxiety many people live with day to day, and it often urns alongside the kind of sleepless overthinking that surfaces once the day’s distractions fall away and the nervous system finally has space to be heard.
Why some people feel this more than others
Anticipatory anxiety isn’t even’y distributed. Temperament plays a role, some nervous systems are simply more reactive from early on, but so does cumulative life experience. A higher load of past stress or unpredictability tends to lower the threshold at which the body decides something might be wrong, which is part of why the same quiet evening can feel restful to one person and quietly unbearable to another.
Current stress also amplifies it. A nervous system already working hard to manage a demanding period at work, a difficult relationship, or ongoing money worries has less spare capacity to correctly interpret ambiguous internal signals, so dread shows up more easily, and over smaller things, than it would during a calmer stretch of life. None of this is a measure of resilience. It’s simply a measure of how much the system currently has on its plate, and it shares a lot of common ground with the kind of overthinking that tends to fill the gaps once the dread itself has shown up.
Why typical relaxation advice can fall flat
Being told to ‘just relax’ rarely helps, and for some people, deliberate stillness can briefly make things feel worse than better. This is a recognised phenomenon: early research by Heide and Borkovec in the 1980ss identified what’s sometimes called relaxation-induced anxiety, where the act of slowing down removes the busyness that had, until then, been quietly masking an underlying alarm. Without anything to distract from it, the unease becomes more noticeable, not less, at least to begin with.
This doesn’t mean relaxation is the wrong goal. It means the route there usually needs to go through the body, not around it.
What actually helps regulate this
Orienting techniques tend to help precisely because they give the nervous system new, present-tense information to work with. Actively looking around the room, naming what you can see and hear, lets the body register, rather than simply be told, that the current moment is safe.
Rhythmic movement, walking, stretching, anything physical and repetitive, also helps regulate through the body rather than relying purely on thought to do the work. And putting the feeling into words, even something as simple as ‘my body feels like something’s wrong, even though nothing actually is right now’, genuinely helps. Neuroscientist Matthew Lieberman’s research on affect labelling found that naming an emotional state measurably reduces activity in the amygdala, essentially giving the thinking brain a foothold back into a process that started entirely in the body.
Saying that, working cognitively can help too. According to Kotler et al.’s (2026) research, the traumatised brain struggles to think of alternative possibilities for why their heart might be racing or their palms might be sweating. A conversation with a trusted person, or therapist, exploring what some alternative possibilities could be, can help to train the brain to look for alternatives that aren’t always ‘danger is coming’.
None of this resolves the deeper pattern overnight, and it isn’t meant to. For a nervous system that’s been on alert for a long time, recalibration tends to be gradual rather than immediate.
If this feeling is a frequent visitor rather than an occasional once, particularly if it’s been there for years without an obvious source, it’s often a sign that the nervous system’s baseline settings could use some genuine recalibration, which is difficult to do alone.
