How the Dreamometer Works

01What the Dreamometer is

The Dreamometer™ is a private record of the dream themes most commonly reported by people who submit dreams through In Your Dreams. Every reading produced through the service includes a brief, optional question asking whether the dreamer is willing to contribute their detected symbols to the visible record. Those who consent add anonymised rows to the underlying table; those who decline contribute nothing.

The dashboard at dreamometer.app displays the resulting symbol frequencies in aggregate. It is updated continually as new readings are submitted.

The Dreamometer is owned and operated by In Your Dreams. The dataset, the visualisation, and the methodology behind it are proprietary. The name Dreamometer™ is a trade mark of In Your Dreams.

02What is collected

From every consenting contribution

For each consenting reading, the following anonymous fields are recorded:

• Detected symbols — the dominant symbols identified in the dream text (e.g. Falling, Water, House)
• Country — derived from the contributor’s IP-geolocation at time of submission, then discarded
• Age band — self-reported in broad ranges
• Pronouns — self-reported
• Mood at submission — selected from a small list
• Felt quality of the dream — selected from a small list (e.g. strange, peaceful, urgent)
• Emotional tone — a positive, negative, or neutral classification
• Timestamp of submission — date and hour, no finer precision

What is never collected

The full dream text, the contributor’s name, email address, IP address, payment information, or any other identifier is not recorded in the Dreamometer record. The dream text itself remains private to the contributor and is never published.

03How symbols are extracted

When a consenting reading is processed, the dream text is read by an automated symbol-extraction step that identifies the most dominant themes present. The extraction returns a short list of canonical symbol names — for example, a dream about pursuit through a corridor might return Being chased and House. These canonical names are what appear in the dashboard counts; the original dream text is not stored alongside them.

Interpretive context shown elsewhere in In Your Dreams draws on five public-domain texts spanning antiquity to the modern age — four available via Project Gutenberg, and Artemidorus' Oneirocritica via the EEBO Text Creation Partnership — but the Dreamometer page itself shows only the aggregate symbol frequencies, not interpretations.

04The atmospheric readings

The dashboard displays two atmospheric values alongside the dream-symbol counts: a Schumann resonance reading and a geomagnetic activity reading.

Schumann resonance

The Schumann resonance is the natural electromagnetic frequency of the Earth-ionosphere cavity, with a documented fundamental of approximately 7.83 Hz. It sits at the boundary between alpha and theta brainwave bands — the same band associated with REM-stage dreaming. The Dreamometer displays this baseline value as ambient context. It is not a real-time measurement of any individual reading.

Geomagnetic activity (Kp index)

The Kp index is a 0–9 scale of global geomagnetic disturbance, published by the U.S. National Oceanic and Atmospheric Administration. Peer-reviewed research has proposed an association between elevated geomagnetic activity and dream bizarreness via the pineal gland’s response to electromagnetic conditions and its effect on melatonin secretion during sleep. The Dreamometer surfaces the current Kp reading as ambient context. It does not claim a causal relationship with any specific dream.

05Experimental research metrics

The dashboard surfaces several further readings in the flanking Collective Themes and Collective Currents panels. The Collective Theme and Theme Tide are descriptive summaries of the archive’s own content, drawn from nothing but the symbols and feelings already collected; they assert no outside influence. World Events is a parallel record of the waking world, shown beside them but never joined to them. The remaining three — Attention Tide, Collective Dream Weather, and Noosphere Drift — are framed as open research questions rather than validated findings: each draws on a single peer-reviewed reference, and each has known data gaps that limit what can presently be tested. None is presented as an established dream driver.

Collective Theme (The Thread)

Unlike the other readings in this section, the Collective Theme is not a hypothesis about an outside influence on dreams — it is a direct description of the archive’s own content. Each day an automated language-model step reads the most frequent dream symbols of the preceding seven days together with the distribution of recorded feelings, and names the single theme that best ties them together. It is given only this de-identified aggregate: no dream narratives are used, because none are stored, and no external information — news, events, dates, public figures or seasons — is provided to it. The reading describes only what the dreams share. It makes no claim about cause and no prediction.

The principle it rests on is the most established in the field: the continuity hypothesis (Schredl and Hofmann, 2003), which holds that dreams reflect waking concerns, so that a widely shared experience tends to produce shared dream content — the same mechanism documented in the pandemic-era findings cited under Collective Dream Weather. The theme appears only once the seven-day window holds at least thirty distinct dreams; below that, the dashboard shows that it is still gathering. The dated symbol and emotion series it is built from is retained, so that any relationship between collective dream content and real-world events can be examined later — but that relationship is left to be discovered in the data, not asserted by the display.

Theme Tide

Theme Tide reads whether the current collective theme is emerging, holding, or turning. It is computed without a language model, as the cosine similarity between each symbol’s share of the last seven days and its share across the preceding thirty — a standard measure of how far two distributions overlap. A high overlap reads as holding (the same constellation persists), a moderate overlap as turning (the mix is shifting), and a low overlap as emerging (a largely new constellation). It is shown only when both windows carry enough symbols to compare; below that it reads as forming. It introduces no external data and makes no causal claim — it simply describes how stable the archive’s own recent symbol pattern is over time.

World Events

Alongside the dream readings, the dashboard shows a daily record of notable world events from the Wikipedia Current Events Portal, retained with its source revision for reproducibility, displayed beside the collective dream theme as an independent reading. The instrument makes no claim that any event caused any dream; the two are placed together and left unjoined, so a reader may reflect and a researcher may later test for correlation — using the media-exposure control to distinguish a genuine shared-experience effect from direct media influence. Event data never enters the generation of the dream theme.

Attention Tide

The research question is whether sharp concentrations of global attention on a topic are followed, within roughly 24–72 hours, by measurable increases in related dream symbols, themes, words, or emotions. The reference paper is Nghiem and colleagues, PLOS ONE, 2016, which establishes search-trend data as a normalised measure of public interest and notes that online news itself shapes search patterns.

Most of the dream-side data required for this comparison — daily symbol counts, daily emotional tone, country code — is already collected. The principal gap is a single optional question at submission asking whether the dreamer had encountered news or social-media coverage of a major topic before sleeping. Without that control, any correlation between attention spikes and dream content cannot be cleanly separated from direct media influence.

Collective Dream Weather

The research question is whether major shared emotional events — disasters, celebrations, periods of widespread grief or fear — correlate with shifts in dream emotional tone and recurring themes across geographically dispersed dreamers. The reference paper is Gorgoni and colleagues, Neuroscience & Biobehavioral Reviews, 2022, which documents pandemic-era increases in dream frequency, intensity, and distressing content.

This is the most research-ready of the four experimental metrics, because the dream-side fields it depends on — the daily feel distribution, country-level submission counts, and AI-extracted symbols by date — are already in place. What remains to be wired in is a structured external event feed and the same event-awareness question identified under Attention Tide.

Noosphere Drift

The research question is exploratory: whether dream-pattern clustering across users shows any relationship with external experimental anomaly datasets — specifically, the random-number-generator deviation archive maintained by the Global Consciousness Project. The reference paper is Nelson and Bancel, Explore: The Journal of Science and Healing, 2011, which describes that project’s hypothesis. The interpretation of the underlying anomalies remains controversial and the literature is not a validated dream-research signal.

The Dreamometer’s posture on this metric is deliberately reserved. The reading is framed as a comparison against an external experimental dataset that already exists, not as a measurement of collective consciousness. Symbol co-occurrence patterns are derivable from data already collected; deeper analyses would require semantic-similarity measures or additional submission fields (lucidity, déjà vu, precognitive-feeling flags) that are not currently captured.

A complete field-level mapping — including which data points are currently collected, which are recommended additions, and the references with DOIs — is maintained internally and available on request for researcher review.

06What the Dreamometer is not

The Dreamometer is not a clinical or diagnostic instrument. It is not a peer-reviewed research dataset. It is a private, ongoing record of the symbolic vocabulary that the people who use In Your Dreams report, in aggregate. Its purpose is descriptive and personal — a way for the wider community of dreamers to see themselves reflected in the patterns of human dreaming.
