Awe — the emotion arising when the perceived vastness of an experience exceeds the individual's current schemas for understanding it — is the subject of a growing research programme in positive psychology and affective science led by Dacher Keltner of the University of California, Berkeley. Keltner and Jonathan Haidt's foundational 2003 paper defined awe as involving two core appraisals: vastness (the stimulus is much larger than the self, literally or conceptually) and need for accommodation (existing mental structures cannot assimilate the experience without modification). The emotion is accompanied by a characteristic suspension of the ordinary chatter of self-referential thought, a shift from self to something beyond the self, and often by physical responses — goosebumps, arrested breathing, tears — that are themselves involuntary markers of the state's intensity.
Keltner's subsequent research documented that awe experiences reliably produce several cognitive and prosocial effects: decreased self-salience (reduced preoccupation with personal concerns), increased sense of being part of a larger whole, enhanced critical thinking (resistance to misleading statistical arguments), and increased prosocial behaviour toward strangers. These effects have been replicated across multiple laboratory paradigms using awe elicitors ranging from natural vistas to architectural spaces to humbling scientific facts. The finding that awe specifically reduces self-salience while expanding awareness of the collective suggests that it represents a genuine altered state — a temporary reorganisation of the self-other boundary — rather than merely a pleasurable emotion.
The German theologian and philosopher of religion Rudolf Otto (1869–1937) developed one of the most influential phenomenological analyses of religious experience in his Das Heilige (The Idea of the Holy, 1917). Otto's concept of the numinous — the quality of the holy as a direct, non-rational experience distinct from any ethical or cognitive content — has remained indispensable for the analysis of intense encounter experiences including close encounters with anomalous phenomena. The numinous is characterised as mysterium tremendum et fascinans: a mystery that is simultaneously terrifying and fascinating, producing a specific quality of awe-dread (tremendum) unlike ordinary fear, and an irresistible attraction (fascinans) unlike ordinary interest.
Otto's phenomenological description maps precisely onto many close encounter reports, which characteristically involve the simultaneous, paradoxical combination of extreme terror and extreme fascination — a quality that distinguishes the encounter experience from ordinary frightening events, in which the typical response is purely aversive. This dual quality — both repelling and irresistibly drawing the witness — has been cited by John Keel, Jacques Vallée, and others as one of the most consistent and phenomenologically significant features of the encounter record, suggesting that whatever the Phenomenon is, it engages neurological and psychological systems that are specifically tuned to the numinous.
Psychologist Abraham Maslow coined the term peak experience to describe the moments of highest happiness, fulfillment, and transcendence in human life — experiences he studied through interviews with self-actualised individuals and later with the general population. Peak experiences share a characteristic phenomenological profile: a sense of cosmic unity or integration; perception of beauty, goodness, and truth as inherent in the world; transcendence of time, space, and self; feelings of meaningfulness and profound significance; and often an episodic quality that makes them feel categorically different from ordinary experience. Maslow found that peak experiences correlated with psychological health and integration, and proposed that they represent genuine glimpses of humanity's highest capacities rather than pathological departures from normality.
Maslow later distinguished peak experiences from plateau experiences — stable, less dramatic but persistent states of serenity, wonder, and enhanced aesthetic perception cultivated by mature self-actualised individuals through practice. The peak/plateau distinction is relevant to the encounter literature: some witnesses report a single intense peak-like encounter that reorganises their worldview, while others describe a progressive entry into a stable state of heightened awareness that persists indefinitely after the initial contact event.
Ontological shock is a term used in UAP and consciousness research circles to describe the specific form of cognitive and emotional crisis that occurs when evidence or experience directly and undeniably contradicts one's fundamental model of the nature of reality. The term gained wider currency through researcher and author Diana Walsh Pasulka (whose work is also treated on the ontological transformation page) and through discussions in the academic UAP research community around the implications of potential confirmed non-human technology disclosure. Ontological shock differs from ordinary surprise or shock in that its object is not a specific event but the structure of reality itself — the witness's entire framework for understanding what exists, what is possible, and who they are becomes suddenly and irreversibly inadequate.
The phenomenology of acute ontological shock includes:
The aftermath of ontological shock includes extended periods of involuntary return to the experience, compulsive attempts to integrate or explain it, oscillation between acceptance and denial of what was experienced, and in many cases, a permanent reorganisation of the individual's values, priorities, and sense of what matters — changes that can be positive and expansive or deeply destabilising, depending on the quality of support available.
The emotional intensity of close encounter testimony is among the most consistent and diagnostically significant features of the case record. John Mack at Harvard noted that his experiencer subjects — across widely varying backgrounds and prior belief systems — shared a quality of emotional weight in their accounts that was categorically different from ordinary recollections. The terror, the overwhelming significance, the sense of having been confronted with something of immense and incomprehensible reality — all were conveyed with a specificity and conviction that Mack found difficult to account for through ordinary psychological mechanisms.
The specific emotional signatures vary by encounter type. UFO witnesses who observe a craft at distance typically report awe, disorientation, and a sense of profound significance — the numinous quality Otto describes. CE-3 witnesses who observe occupants add the specific quality of contact with a radically alien other intelligence. CE-4 experiencers report the full range from terror and violation to transcendence and transformation, often within the same account. The common thread across these variants is high-arousal affect that reorganises memory, attention, and worldview in the manner characteristic of peak and numinous experiences more broadly.
The ecstatic unity reported by a subset of close encounter witnesses — not abduction experiences but positive contact events, particularly those involving contact in meditation or during voluntary CE-5 protocols — may represent the fascinans pole of the numinous without the tremendum: an overwhelming sense of loving, intelligent, vast presence that produces profound expansion and peace rather than terror. The phenomenological overlap between these experiences and the unio mystica of mystical traditions is striking and has been noted by researchers including John Alexander and practitioners within the CE-5 community.
Across nearly all categories of profound encounter experience — UAP sighting, NDE, deep meditative breakthrough, psychedelic peak — a sense of cosmic significance is among the most consistently reported features: the conviction that what has just occurred is enormously important not merely for the individual but for humanity's understanding of its place in the cosmos. This sense is not reducible to egotism or grandiosity — it commonly coexists with a simultaneous sense of personal humility and insignificance relative to what has been glimpsed.
Long-term aftereffect studies — including Pim van Lommel's NDE cohort followed over 8 years, Kenneth Ring's encounter experiencer surveys, and retrospective analyses of psychedelic research participants — consistently document persistent positive changes in the wake of such experiences: reduced fear of death, increased altruism and prosocial behaviour, increased appreciation of ordinary experience, reduced materialism, and increased spiritual orientation regardless of prior religious affiliation. These transformative aftereffects are among the most robust findings in the consciousness research literature, and suggest that high-affect altered states have a privileged relationship to fundamental psychological change that ordinary emotional experiences lack.
