Introduction
Precognition dreams are interpreted as prophetic, or foretelling in diverse cultures (
Kugel 1995;
Laughlin 2013;
Parra 2013). They have been described as
deja vu phenomena (
Eranimos & Funkhouser 2023;
Kumar 2023), which implies that dreams are re-experienced in wake-space. Notable scientific discoveries, which include acetylcholine by Otto Loewi (
McCoy & Tan 2014), benzene ring structure by August Kekule (
Rothenberg 1995), and the periodic table by Dmitri Mendelev (
Shiltsev & Shiltseva 2020) are attributed to precognition dreams. High occurrence of precognition dreams, which is up to 60 % of subjects (
Eranimos & Funkhouser 2023;
Schredl 2009), implies that the phenomenology is not rare. Precognition is, therefore, interpretable as encodings of the future (
Kugel 1995;
Laughlin 2013), although this is not generally accepted (
Laughlin 2013;
Lindsay et al. 2024),
General relativity theory models events in the universe as positions in spacetime coordinates. Unlike events in Euclidean space or geometry that have 3D spatial coordinates, and distinct 1D time coordinate, events in general relativity mechanics occur in 4D spacetime coordinates. Dreams events have attributes of 4D spacetime coordinates that permit Consciousness to revisit past events (
Oluwole 2020,
2022), which implies moving back in time coordinate. Further, it permits Consciousness to observe mixing of past, present, and future events (
Oluwole 2020,
2022). Consciousness in dream spacetime may transit vastly separated regions instantaneously, or very short distances may be interminable to transit (
Oluwole 2020,
2022,
2024). Dream spacetime is, therefore, dynamic unlike static geometry of wake-space. In general relativity formulation, events in the universe are not perceived simultaneously by all observers. Observers moving close to the speed of light perceive events before stationary observers (
Bambi 2018;
Luminet 1998;
Wald 2010). Similarly, observers in strong gravity fields perceive events before those in weak gravity fields (
Bambi 2018;
Luminet 1998;
Wald 2010). There is, therefore, time dilation in special and general relativity theories. Events in dreams typically last less than five minutes, but equivalent events may take decades to execute in wake-space (
Oluwole 2020,
2022). Time dilation between events in dream-space, and phenomenal experiences of wake-space, implies that Consciousness is in relativistic motion in dream-space (
Oluwole 2020,
2022). Very strong gravity in dreams also implies that general relativity theory is applicable to dreams (
Oluwole 2020,
2022,
2024). 4D spacetime attributes in dreams, therefore, suggest the physical basis for precognition. Study was done to determine the existence and physical basis for precognition in dreams.
Methods
Phenomenal experiences of Consciousness during sleep were modeled to occur in dream-space, which has distinct geometrical attributes. Causality is established if events in precognition dreams transform to phenomenal experiences in wake-space. Subjects provided precognition narratives that were experienced at any time in the past. Details included dates of precognition, and of re-experience in wake-space, geographical settings, and entities encountered like human, animal, and inanimates. Human entities included colleagues, family members, and others were provided. Events in precognition included sports, sex, examination, politics, violence, and climate. Subjects also stated if precognition was wished. Minimum desired sample size of subjects to generate enough narratives was 250. It was assumed that one in 100 precognition dreams would transform at random to phenomenal experiences in wake-space. Statistics of proportions were performed. Chi-square test was performed on contingency table of transformed wished, and of unwished precognition.
Prepossessing of Narratives, Word Cloud, and Entity Extraction
Precognition was entered verbatim into text database without editing. To generate keywords, prepossessing included changing words to lower case, removal of typographical errors, double words, extra spaces, punctuation, numbers, dates, and stopwords. All words were lemmatized. Prepossessing for summary, and query using large language model query narratives, and for word embedding was limited to lower case, and removal of contractions, and typographical errors. Modules of Python Programming, version 3.11, 2025, modules included Textacy, NLTK, and regular expression. Keywords were generated for transformed, and untransformed precognition. Word clouds were generated using Matplotlib module of Python Programming.
Rule based entity search algorithm was used to extract themes, geographical locations, time, entities, and events from corpora of precognition narratives using Spacy module of Python Programming. Spatial entities included organizations like hospitals, universities, schools, Churches, and Mosques, while human entities included friends, colleagues, lecturers, policemen, and family. Themes included vocation, sports, socials, religion, sex, climate, and violence.
Computational Linguistics, and Knowledge Graph
Jaccard index was used to compare lexical similarity of transformed, and untransformed precognition. Jaccard index was defined as . Jaccard index was zero when no words were common to both documents, but one when all words were common to both sets of narratives. Bootstrap statistic was performed to determine 95 % CI for Jaccard similarity.
Large language model was used to query dream narratives to determine if precognition encoded knowledge of the future. The algorithm was implemented in Llama index module of Python Programming and Environment. Each narrative was mapped to 1D vector embedding using Llama 3.1 large language model. 1D vectors were arranged to rows of narrative matrix. Cosine distance matrix was generated from narrative matrix, to map narratives to spherical space, where distances are geodesic. Cosine distance matrix was thresholded to adjacency matrix. Networkx module of Python programming was used to generate knowledge or semantic network graph from the adjacency matrix. The knowledge graph was compared with Erdos-Renyi random graph using Wasserstein distance to determine if it was generated by a random process. Statistical significance was tested using Bootstrap statistic. Metrics were calculated for the knowledge graph to determine connectivity, and modularity.
Ethics
Manuscript conforms to ethical guidelines of WMA Declaration of Helsinki–Ethical Principles for Medical Research Involving Human Participants. Ethical clearance, and informed consent were obtained locally. Subjects had complete disclosure of study objectives, assured of confidentiality of personal information, and received no incentives, or inducement. No grants, or financial assistance were received for the study. Generative artificial intelligence was not used for any section of the study.
Results
There were 253 subjects, 141 males and 112 females, with median age 24 years (50 % interquartile range 21–25). Of 280 precognition narratives, 69 (25 %) were transformed to phenomenal experiences in wake-space. Assuming random occurrence of one in 100 precognition dreams, statistical test showed significant transformations at . Proportions (%) of spatial entities like buildings, streets, and administrative regions were 29 (22–36) for transformed precognition, but 33 (28–37) for untransformed precognition. Comparisons of proportions (%) number of human entities like family members, friends, colleagues, lecturers, and policemen were 27 ( 19–33) for transformed precognition, but 22 (18–26) for untransformed precognition. Proportions (%) of occurrences of minutes, hours, or dates were 37 (29–44) for transformed precognition, but 31 (27–35) for untransformed precognition. Events (%) like social gatherings, worship in Churches, and violence had occurrence of 8 (4–13) for transformed precognition, but 15 (12–18) for untransformed precognition.
Commonest keyphrases in the corpus of precognition narratives that have been re-experienced were
house, room, examination, secondary school, 2019, the next day (
Figure 1A); but were
house, room, secondary school, see, the day, church for precognition narratives that have not been re-experienced (
Figure 1B). Jaccard similarity index (95 % CI) between re-experienced and not re-experienced narratives was 0.14 (0.05–0.22) (
).

I was in senior secondary school. It was a night dream. At that time, I was in Abeokuta,Ogun State. In the dream. I was the main character. I saw myself carrying out surgical operation on someone’s left thigh. There were few unknown faces around basically health personnel. I did not wake up immediately in the dream.I recalled the dream on awakening in the morning. After the dream, I realized that some people began to call me doctor in real life. The dream metamorphosed into a wish and ambition to pursue a medical career in the university which became fulfilled 13 years after I had the dream(2010) It may seem as a partial fulfillment relatively in the sense that I am not in a surgical specialty as occurred in dream, but I could also view it as fully fulfilled because at the same time I had the dream, my understanding was that I am going to be a doctor which was attained"

Discussion
Highly significant re-experience of precognition dreams indicates connectivity between dream-space and wake-space. Information, therefore, transfers from dream-space to wake-space, which indicates that precognition dreams are not random events. Hermenutic phenomenology of Freudian dream theory implies that phenomenal experiences of wake-space transform to dreams. Information transfer is, therefore, bidirectional between dream-space and wake-space. Space, time, and events in memory dreams are derived from the cultural settings of subjects (
Oluwole 2019,
2020). Similarly, space, time, entities, and events in precognition are derived from the cultural settings of subjects. These settings include University environment, previous schools, Halls of residence, roads, and geographic entities. Further, precognition themes include social, faith, vocation, sports, climate, and finances. Thus, dream-space and wake-space are coupled information processing system.
The language of Consciousness in dream-space is typically the same language spoken in wake-space (
Oluwole 2022). Vocabulary of memory dreams is comparable to diverse genre of human documents (
Oluwole 2020).
House, room, examination, secondary school, 2019, the next day are the commonest keyphrases in the vocabulary of precognition narratives that are re-experienced (
Figure 1A); but
house, room, secondary school, see, the day, church for precognition narratives that have not been re-experienced (
Figure 1B). Jaccard similarity indicates statistical difference in keyphrases. Dream narratives have been shown to be coherent, even when sequence of events are not feasible (
Oluwole 2020,
2022). The corpus of narratives is summarized as dream journal of an individual by large language model. It also identifies precognition in the corpus. These findings indicate coherence of diverse precognition experiences of subjects. Although phenomenal experience of any observer is qualia (
Hobson 2009;
Kazanina & Poeppel 2023;
Smythies 2003;
Whorf 1952), objective reality is established if multiple observers share similar phenomenal experiences (
Moran 2024;
White 1947). Thus, similar phenomenal experiences of subjects in precognition dreams indicate objective reality, but not qualia.
Phenomenal experiences generate knowledge (
Husserl 2012), which is usually expressed using language (
Husserl 2012). Knowledge graphs are mathematical objects which provide visualization and metrics to assess interactions between entities of systems. Precognition knowledge graph indicates coherent semantics of narratives (
Figure 2). Metrics indicate that precognitive narratives are not descriptions of random phenomenal experiences (
Figure 2).
Figure 2 shows that all pairs of nodes are connected. Connectivity metrics indicates that no precognitive narrative contains information that is isolated from all other narratives. Density of 1.0 indicates maximum connectivity of semantic graph, while average degree centrality of 1.0 indicates that each narrative shares information with at least one other narrative. Global clustering coefficient of 1.0 indicates strong clustering of nodes. Thus, subjects have shared phenomenal experiences of precognition in dream-space.
Precognition Narratives
Dreams 1–5 illustrate re-experience of precognition in wake-space after lag of few hours to 48 hrs. Precognition of examination questions in Dream 1 is re-experienced within hours, but within 24 hours for the delivery of a baby girl that resembles the subject in Dream 2. Precognition of score 67 in chemistry examination in Dream 3 was re-experienced within 24 hours. An unsuccessful Car deal in Dream 4, and positive COVID-19 result in Dream 5 are re-experienced within 48 hours. Thus, precognition do transform to phenomenal experiences of wake-space without changes to order or sequence of events after very short lag.
Dreams 6–13 illustrate re-experience of precognition after lags of up to a decade. These dreams also transform to phenomenal experiences without changes to the order, or sequence of events. Precognition of traveling through many states to a University following admission in Dream 6 is re-experienced within two weeks. A friend who had motor traffic accident in Dream 7, purchase of new Toyota Corolla in Dream 8, perception of University community in Dream 9, and prize in mathematics in Dream 10 are re-experienced within few months. Sex in Dream 11 is re-experienced five years later, while in Dream 12 precognition of WhatsApp video feature is re-experienced 8 years later. Graduation as doctor in Dream 13 is re-experienced after a decade. Thus, long delay before re-experience do not change the sequence of precognition events.
Dreams 14-15 illustrate changes to the sequence of precognition events when re-experienced in wake-space. Precognition scores in Biochemistry examination, which were 62 for the subject, but 50 for a colleague in Dream 14, reversed when re-experienced. Dresses worn in Dream 15 changed when re-experienced. Information entropy measures phenomenology of configuration changes to sequence of events, signals, or messages from source to destination. Thus, information entropy occurs when precognition transforms to phenomenal experiences of wake-space.
Dreams 16–20 illustrate precognition dreams that have not been re-experienced. In Dream 16, precognition was an Aircraft parked on a street, but took off before subject finished packing the luggage. This dream, however, is unlikely to be re-experienced without changes since commercial aircrafts do not park or taxi on neighborhood roads. Sibling is recruited to football Club in Dream 17, while in Dream 18 potential entry to Residency training in Massachusetts General Hospital, Boston is perceived. Consciousness is Consultant Physician in a big Hospital in Dream 19, but is living with family in the USA in Dream 20. Precognition events in Dreams 16–20, therefore, contain symbols, representations, or metaphors of real events. Metaphors in dreams are interpretable only in the context of subjects (
Hartmann 1996,
2010). Metaphorical precognition is, therefore, interpretable as encrypted or ciphertext that can be interpreted only by persons with encryption keys. Metaphorical precognition, therefore, explains statistical difference between vocabulary of transformed, and untransformed precognition. Thus, cryptography is observable in precognition dreams.
Causality of Precognition, and Spacetime Theories
Causal events precede their effects in special and general relativity mechanics (
Chatterjee 2013). Precognition is causal event in dream-space, where Consciousness is in relativistic motion, and gravity is very strong, while re-experience of precognition is the effect in wake-space, where motion is very slow, and gravity is very weak. The cause, and the effect are, therefore, in distinct spacetimes as modeled in special, and general relativity mechanics. Causal events in the reference frame of observers moving very close to the speed of light away from stationary observers are perceived immediately, but after a lag by stationary observers. Further, the intervals between events, or frequency of signal increases as the fast observer moves away. Changes in the frequency of signals termed redshift is also described as time dilation, such that stationary observers need more time to experience the same event. Time dilation, which is central concept in special relativity theory (
Carroll 2014;
Einstein 1920), is similar to Doppler effect, which is observable at low speeds in wake-space. Doppler effect increases the frequency of signals when the source moves towards stationary observer, but decreases it when the source moves away. Time dilation also occurs in general relativity mechanics between observers in strong gravity fields and those in weak gravity fields (
Bambi 2018;
Luminet 1998;
Wald 2010). Thus, relativistic motion of Consciousness in dream-space, where gravity is very strong, provides physical model for precognition dreams.
Spacetime concepts in philosophy include presentism, eternalism (
Savitt 2006), and Block universe (
Bouton 2017;
Margoni 2024). Presentism asserts that only now, or present exists, while eternalism asserts that past, present, and future exist (
Savitt 2006). Block universe, however, asserts that past, present, and future coexist (
Bouton 2017;
Margoni 2024), but not ordered. Although Block universe appears counter-intuitive, it is observable in dreams where past, present, and future coexist in the same event. Thus, philosophical concept of Block universe models perception of past, present, and future in dreams.
Conclusions
Precognition transforms to phenomenal experiences of wake-space. Transformation to wake-space is deterministic if the sequence of precognition events is unchanged. Changes, alterations, and reordering of precognition events indicate information entropy. Precognition, however, can be encrypted such that symbols or representations of entities and events are presented. Transformation, therefore, has to be decrypted. There are, therefore, types of precognition which generate knowledge, and serve purposes that transcend mere forecasts of future events. Thus, there is causal relation between precognition events, and phenomenal experiences of wake-space.
Dream-space has attributes of 4D spacetime, while wake-space has attributes of 3D spatial coordinates, and distinct 1D time coordinate. Special and general relativity mechanics, Block universe, and quantum mechanics are models of events in dream-space. Dream spacetime permits Consciousness to perceive the past, present, and future. It also permits motion themes that are not feasible in wake-space. Relativistic motion of Consciousness in dream-space, and time dilation are the physical bases for precognition. Thus, dream spacetime permits Consciousness to move in time dimension to the past, and to the future.
