Introduction
According to the U.K. Met Office, fog is one of the trickiest weather phenomena to forecast. On the website (https://weather.metoffice.gov.uk/learn-about/weather/types-of-weather/fog) fog is defined as ‘obscurity in the surface layers of the atmosphere, which is caused by a suspension of water droplets’. This technical definition is also given in spatial parameters: ‘fog is the name given to resulting visibility less than 1 km’, although in forecasts for the public in everyday life this generally refers to ‘visibility less than 180 m’. It seems that fog makes it difficult to see things around us. This lack of visibility comes with certain warnings attached. The Met Office warn: ‘If you really cannot see, you should consider stopping until it is safe to continue’. These meteorological observations are ones held in mind as I think with David Bissell's moving paper about ‘brain fog’. Fog has certain characteristics which implicate lived geographies and hold potential dangers, partly as we cannot see things around us or ways forward.
Bissell's account helps us understand something of the disruptive capacity of fog. A brain fog can be imagined in ways as limiting as atmospheric fog, but also in profoundly private ways. Medically, brain fog is recognised as a diagnostic symptom across various conditions, invoking a recent ‘brain fog scale’ (Debowska et al., 2024) and ‘calls to action’ (Haywood et al., 2025), including in mental ill-health fields, as many studies note the association between depression and seemingly depleted states of cognition. Although brain fog is only explicitly mentioned occasionally in this context, one mental health clinician argues that it is important to distinguish between
If foggy things like these are said, then it seems, at least for this clinician, that depression can be seen, ironically enough, more clearly (Parker, 2022). Such testimonies certainly chime with Bissell's (2025: 2) view that brain fog ‘is an embodiment characterised by difficulty thinking, a lack of mental lucidity, an inability to focus, and impaired memory’. Critically, as Bissell notes, such experiences are ones that we often overlook in disciplinary contexts, arguing that ‘most of our current geographical accounts of bodily experience conjure a version of our being in the world as present, engaged, and capacious’. Considering the observations above, I will respond to Bissell's invitation to think
Delusional geographies
To illustrate, I will briefly reference a past paper on ‘delusional geographies’ (Parr, 1999), wherein I focussed on narrated experiences of people with a named mental illness and their ‘hazy experiential mesh between the conscious and unconscious, irreducible to either’ (Parr, 1999: 674). It is to this haze that I now return, prompted by Bissell's provocative work, revisiting an uncertain terrain that somehow seems simultaneously familiar, challenging, new and important.
In the 1999 paper, I sought to write, in a very general way, towards psychoanalytic thinking as a way of framing the disruptive nature of delusion, but more generally I was steering a course that I have repeated many times over the years: to attend to
Drawing loosely on Parr (1999), back then I positioned people experiencing delusion as existing in a confusing flow between ‘sane’ and ‘insane’ states. Often people reported feeling dislocated; seeing and hearing things that others cannot, sometimes feeling possessed or controlled or unbounded, in a ‘disruptive mesh’. I argued that this feeling-state had implications for how people in thrall to delusion experience the scales of body, home and city. Although we cannot understand the experience of brain fog in an exactly similar way, writing of
Seeing the (low) light
As we heard earlier, meteorological fog obscures light and visibility and we are often warned of its dangers. More recently, I have been working with people who experience seasonal affective disorder (SAD) (Bodden et al., 2024a, 2024b, 2025) and their lived experience of winter. Narrative accounts of SAD bring not only descriptions of the muzzy affect of low light, but explicit reference to cognitive fog, often brought on by darker days:
In times of danger, when thoughts cannot focus, routes or purposes cannot be remembered, and when things cannot be seen because they are not wholly visible to the foggy self, then people with SAD may retreat to familiar spaces and places, perhaps indoors, although admittedly, as Bissell explains, these interiors may also hold little comfort.
The Met Office descriptions tell us that fog is a fluctuating state, one that moves in, dwells, and sometimes dissipates. For those who experience this ebb and flow, this space in-between becomes clearer in new light:
Conclusion: A politics and practice of empathetic solidarity
What of those always or still lost in the fog? When considering the disruption of delusional experience, I used political scientist Glass (1989: 212) as he wrote of the terrifying ‘placelessness’ of non-consensual reality: ‘Delusional time and space replace the self-rootedness and identity … the result is a loss of the self's public being, a reversion to private knowledge systems, and most important, a complete loss of the sense of community’ (cited in Parr, 1999: 685). In my original discussion of Glass, I considered the narratives of those experiencing delusion and how, at some points in their experience, they tried – all the time struggling – to anchor themselves meaningfully through engagement with material and social spaces and places. Those rather mundane points were made as gentle cautions about a scholarly celebration of un-boundness and multiple, fluid selves common in the fashionable post-structuralism of the times. (The continuing dangers of ‘romanticising’ being ‘undone’ are also identified by Bissell.) Likewise, and again now, I might conclude that the analysis of dispossession, disengagement and displacement in Bissell's contribution references an exhausting state which ultimately is difficult to witness, interpret and not least embody.
This conclusion is not just a reluctance to get on board with the challenging epistemologies of ‘negative geographies’ (Bissell, 2025: 3), but more representative of my own solidarity with those suffering foggy brains and my wish to help mitigate suffering, rather than simply ‘making it part of the academic project’. As I read Bissell's final line, ‘I sometimes miss being in the world’, with deep empathy and understanding, I find myself advocating a particular kind of politics of knowledge in response. As much as I am attracted as an academic geographer once more to dwell in and with the foggy in-between spaces of disruptive embodied experience, I mostly want this work to
