An empty building can feel wrong even when you cannot identify a threat because your brain is comparing the scene with a learned pattern of how that place should look and sound. When the layout, lighting, signs of use, or social activity depart from that pattern, the setting becomes difficult to read. Alexander Diel and Michael Lewis’s 2022 study of physical-place judgments found an uncanny-valley-shaped link between perceived realism and uncanniness, associating the feeling with structural anomalies. That evidence concerns people’s perceptions of places, not proof that every abandoned building is dangerous or that one mechanism explains every uneasy reaction.
The short answer: a familiar place has stopped behaving as expected
Schools, offices, malls and apartment blocks carry strong expectations. You anticipate corridors leading somewhere, lights working, signs making sense, and other people appearing at ordinary times. An abandoned version preserves enough of the old identity to activate those expectations, yet removes or alters the cues that normally confirm them. The result is a setting that is recognizable but not fully legible.
Diel and Lewis described this pattern as an uncanny valley of physical places in their 2022 paper, “Structural deviations drive an uncanny valley of physical places,” published in the Journal of Environmental Psychology (volume 82, article 101844). Their central finding was that deviations from familiar configurations were associated with uncanniness. In practical terms, a place may feel “off” when its arrangement, appearance or environmental signals do not fit the configuration you have learned to expect.
Emptiness is therefore an amplifier rather than a complete explanation. A vacant building removes ordinary confirmation—voices, movement, open businesses, staff, maintenance and purposeful traffic—so unusual features stand out. But the study does not show that emptiness alone causes fear, nor that everyone responds to the same features in the same way.

How structural deviations create an uncanny feeling
Recognition without a stable interpretation
Most built environments are easy to categorize. A school has classrooms, a bell schedule and circulation routes; a shopping mall has storefronts, advertisements and public movement; an office has desks, reception areas and work-hour activity. An abandoned site can retain the shell while losing the functions that made each element intelligible. A locked classroom with faded posters, a food court with no vendors, or an elevator that opens onto a dark floor is still recognizable, but the normal explanation no longer fits.
This mismatch is different from seeing something completely unfamiliar. A wholly unknown landscape may be puzzling, yet it does not violate a detailed expectation. An old familiar building supplies a template and then breaks it. Diel and Lewis’s result supports that distinction: structural deviation, not mere age or emptiness, was associated with the uncanny response.
Small inconsistencies accumulate
Unease often comes from several modest discrepancies rather than one dramatic feature. A corridor may be clean but unlit; a clock may be stopped while a newer emergency sign remains bright; a door may be propped open even though the building appears unused. Each cue is ambiguous on its own. Together they make it harder to decide whether the place is active, recently deserted, being repaired, or deliberately concealed.
These are examples of interpretation, not a checklist proven to trigger everyone. The relevant question is whether the scene supplies a coherent account of what the building is doing now. When it does not, the viewer experiences uncertainty as an affective “wrongness.”

Why an empty public place can feel more disturbing than a private room
The social purpose of a setting changes how absence is interpreted. Diel and Lewis found that human presence did not have one uniform effect: people’s presence reduced uncanniness in distorted indoor public places but increased it in private rooms. This makes an empty school corridor or mall especially striking, because those spaces are normally shared. A person in a public hallway can restore the expected social script. In a private bedroom, by contrast, an unexpected person may itself be the anomaly.

| Setting | Expected social use | What absence or presence can signal | Likely interpretive problem |
|---|---|---|---|
| School corridor after hours | Regular circulation by students and staff | No people removes a normal confirmation of purpose | Is the building closed, forgotten or still operating? |
| Shopping mall concourse | Continuous public movement and commerce | A lone person may make the public space readable again | Why are the shops and services inactive? |
| Office reception area | Visitors, employees and administrative activity | Empty desks and dark rooms conflict with the building’s design | Is the site temporarily closed or permanently abandoned? |
| Private room | Restricted occupancy by an expected individual | An unanticipated person can increase the anomaly | Who belongs here, and why are they present? |
The table describes the study’s public–private distinction as an interpretive framework, not a universal rule. A crowded public place can still feel threatening, and a private room can feel reassuring when the occupant and circumstances are expected.
Dim light, occlusion and the mystery of not knowing
The 2022 paper discusses threat ambiguity, mystery, occlusion, dim light and the difficulty of inferring information about a setting as relevant concepts. These ideas help explain why an already irregular building can become more unsettling at dusk or in a power outage. Darkness hides boundaries; a blocked doorway prevents you from seeing whether a room continues; a confusing floor plan makes it difficult to predict where a sound originated. The environment offers fewer reliable cues with which to test an explanation.
It is important to distinguish concepts discussed in the paper from effects that the experiment directly isolated. The study supports the importance of familiar configuration and structural deviation. It does not establish that every dim corridor, occluded doorway or mysterious room independently produces a measurable fear response. Those features are plausible contributors because they make the place harder to read, but their influence depends on context, prior knowledge and the viewer.
Why silence and residual signs of life matter
Sound and activity normally provide timing information: a lift motor, ventilation fan, conversation or delivery tells you that the building has a present-tense function. When those signals disappear while traces of former use remain, time becomes ambiguous. Peeling notices, a calendar, abandoned furniture or a still-readable directory can make the site feel paused rather than simply empty. That “between states” quality is one reason people describe certain scenes as liminal.
Liminal spaces: a useful term with limits
“Liminal space” is often used online for transitional or ambiguous imagery—hotel corridors, vacant terminals, stairwells or brightly lit rooms with no visible occupants. Diel and Lewis use the term for ambiguous or eerie physical-place imagery while noting that liminality has other meanings in scholarship. It should not be treated as a synonym for “creepy,” and not every transitional place is unsettling.

A liminal image becomes potent when it combines a recognizable setting with missing context. A photograph of a closed swimming pool may evoke a stronger response than an unfamiliar ruin because the viewer knows what the pool is for and can imagine its normal users. The image supplies enough information to trigger a social script, but not enough to complete it.
What online Backrooms culture adds—and what it does not prove
Internet Backrooms stories and images turn this kind of uncertainty into a participatory digital environment. Repeating rooms, artificial lighting, missing exits and unclear rules invite viewers to explore an imagined place while remaining physically safe. The experience is place-like without requiring an actual abandoned structure.
In a 21 May 2026 announcement, Lancaster University described research on online Backrooms as a form of participatory digital environment that can feel immersive and unsettling despite not being a real place people physically visit. The university quoted co-author Dr Sophie James, Lecturer in the Department of Marketing: “Our research shows that people are increasingly drawn to intense emotional experiences in spaces that are not physically real, but still feel vivid and meaningful.”
This cultural evidence shows how ambiguity can be designed and shared online. It does not establish how people respond to real abandoned buildings, and it should not be used as proof that digital Backrooms reactions and on-site reactions have the same causes.
An eerie feeling is not evidence of actual danger
Subjective uncanniness and objective risk are separate questions. A building may feel menacing because its layout is hard to interpret while posing no immediate threat; another may look ordinary while containing serious structural, environmental or criminal hazards. Your sensation cannot, by itself, identify which situation you are in.

Research on vacant housing illustrates why context matters. A 2019 mixed-methods study summarized by the U.S. National Institute of Justice examined a high-crime neighborhood in Ohio. It consulted 35 ex-offenders, police officers and residents, and reported that streets where abandoned houses were razed had a lower proportion of neighborhood crime after removal. Interviewees described abandoned houses as potential cover, unoccupied spaces and easy targets. The findings concern actual vacant housing in a specific neighborhood and rely on a particular study design; they do not show that an observer can infer danger simply from an eerie-looking building, or that all vacant properties increase crime.

Do not enter without permission. The fact that a place feels uncanny is neither a safety clearance nor a diagnosis of your mental health.
A practical framework for understanding your own reaction
You can analyze the feeling without assuming that the building is supernatural or dangerous. Use the following questions while viewing a photograph, film or a legitimately accessible public area:
- What was this place designed for? Name the expected users, activity and schedule. A school, hospital and private home supply different social scripts.
- Which structural feature breaks the script? Look for a blocked route, altered room sequence, mismatched scale, damaged facade or signs that no longer correspond to the current layout.
- How readable is the space? Note darkness, glare, occlusion, confusing signage, inaccessible exits and sounds whose source you cannot locate.
- What evidence of time is present? Separate signs of recent closure from long-term decay. A fresh notice and decades-old furniture create a different ambiguity.
- Is a person expected here? In a public setting, an ordinary passerby may restore the social pattern. In a private room, an unexpected person may intensify the anomaly.
- What independent evidence bears on risk? Check permission, official warnings, structural assessments and local conditions rather than using your emotional response as a proxy.
This framework keeps perception and hazard assessment separate. It also explains why two viewers can see the same image and report different levels of unease: they may bring different familiarity, expectations and assumptions about who should be present.

Empty schools
A school is organized around predictable circulation and collective activity. After closure, rows of rooms, lockers and noticeboards remain but the timetable and voices vanish. The architecture still announces “shared institution,” while the scene denies its normal users. A locked classroom is therefore not inherently frightening; its effect depends on how strongly the viewer notices the mismatch and how much of the layout remains understandable.

Abandoned malls
Malls amplify the contrast between public scale and missing crowds. Wide concourses, shopfronts and food areas are designed to be read through movement and commercial signals. When those signals stop, the building can feel oversized and purposeless. A lone authorized visitor may make the space less uncanny by restoring a public-use cue, consistent with the public-setting result reported by Diel and Lewis.
Closed offices and factories
Workplaces contain many functional clues—security desks, schedules, equipment and directional signs. If those clues remain while operations have ceased, it becomes difficult to tell whether the site is between shifts, being dismantled or abandoned. Machinery, chemicals, unstable floors or live utilities can create real hazards, but those hazards must be established separately from the atmosphere.
What the evidence does not establish
- There is no representative statistic in the cited material for the share of people who find empty buildings unsettling.
- The 2022 place-perception study does not provide a single universal explanation for every eerie reaction and does not show that emptiness alone causes fear.
- Human presence does not always make a setting feel safer; its effect differed between distorted public places and private rooms.
- Dim lighting, occlusion, mystery and threat ambiguity are discussed as relevant concepts, but they should not be presented as separate effects experimentally proven by that study.
- The Ohio vacant-housing findings cannot be generalized to every abandoned building or neighborhood.
- Backrooms research concerns digitally mediated environments and does not establish responses to entering real abandoned sites.
The most useful way to think about the unease
Empty and abandoned places feel unsettling when a recognizable environment no longer supplies the configuration, activity and information needed to explain itself. Structural deviations create the core sense of wrongness; missing social cues, dimness and blocked sightlines can make that uncertainty harder to resolve. Public and private settings reverse some expectations about the effect of human presence. Online liminal imagery and Backrooms stories demonstrate that the same ambiguity can be crafted without a physical location.
The feeling is real as a perception, but it is not a verdict about the building. To decide whether a place is actually unsafe, use evidence about permission, construction, environment and local crime—not the atmosphere alone.
