Overview

Montague Ullman transformed dream research into a laboratory science by combining psychiatric expertise with rigorous experimental methodology. Ullman’s foundational insight was that the altered neurophysiological state of sleep (particularly the rapid-eye-movement (REM) phase) might create optimal conditions for the reception of telepathic information. Rather than treating dreams as clinical material or symbolic narratives, Ullman designed controlled experiments in which sleeping participants’ brain activity was continuously monitored while distant agents attempted to transmit target information. This approach married the clinical credibility of a major medical institution with the experimental rigor demanded by parapsychology, producing a body of work that remains central to contemporary dream-psi research.

Ullman’s career reflected a lifelong commitment to integrating parapsychology into mainstream science and medicine. Ullman recognized that the dismissal of psi phenomena by the psychiatric and medical establishments stemmed partly from methodological skepticism and partly from conceptual barriers, the assumption that anomalous cognition violated fundamental principles of neurobiology and physics. By anchoring dream-telepathy research in polysomnographic monitoring, statistical analysis, and institutional legitimacy, Ullman sought to demonstrate that psi could be studied with the same rigor applied to any other psychological or neurophysiological phenomenon. Ullman’s theoretical writings extended this vision, arguing that parapsychology and psychiatry shared common ground in understanding consciousness, perception, and the boundaries of individual minds.

Life and career

Ullman founded the Maimonides Medical Center Dream Laboratory in 1962, establishing what would become the most productive institutional center for experimental dream-psi research in the twentieth century. The laboratory’s creation reflected Ullman’s conviction that parapsychology required institutional homes within mainstream medicine and academia. Ullman’s psychiatric training and clinical experience provided both credibility and insight: Ullman understood the phenomenology of altered consciousness, the neurobiology of sleep, and the clinical significance of anomalous experiences that patients reported but psychiatry typically pathologized or dismissed.

Stanley Krippner joined the Maimonides laboratory in 1964 and became Ullman’s primary collaborator in developing and executing the dream-telepathy research program. Krippner brought expertise in psychophysiology and experimental design, and together Ullman and Krippner created a research partnership that would define the field for decades. Charles Honorton, another major figure in parapsychology, also collaborated with Ullman and Krippner on several landmark studies, particularly the precognitive dream research and art-print transmission experiments.

Throughout the 1960s and 1970s, Ullman’s laboratory conducted hundreds of experimental sessions, each involving a sleeping participant whose EEG and eye-movement patterns were continuously recorded. The experimental design was straightforward in principle but demanding in execution: a sender in a distant room would be given a randomly selected target image or art print; the sleeping receiver would be awakened during REM periods and asked to report dream imagery; independent judges would later compare the receiver’s dream narratives to the target and decoy images, rating the correspondence. The use of polysomnographic monitoring ensured that receivers were genuinely asleep and in REM sleep when target transmission was attempted, eliminating the possibility that conscious sensory leakage or inference could account for hits.

Ullman’s theoretical contributions extended beyond methodology. Ullman proposed that the sleeping brain, freed from the constraints of waking consciousness and sensory input, might be inherently more receptive to subtle or anomalous information. Ullman argued that psi phenomena were not exotic violations of neurobiology but rather expressions of capacities that the brain possessed but that waking consciousness typically suppressed or failed to access. This perspective reframed parapsychology from a marginal challenge to established science into a legitimate inquiry into the full spectrum of human consciousness and perception.

In addition to experimental work, Ullman authored and edited numerous theoretical and clinical works examining the intersection of parapsychology and psychiatry. Ullman’s writings addressed how psi phenomena related to mental health, psychopathology, personality, and the nature of consciousness itself. Rather than treating psi as an isolated curiosity, Ullman integrated anomalous cognition into a comprehensive vision of human psychology and neurobiology.

Research

Dream-Telepathy Experiments

The core of Ullman’s research program involved controlled experiments in which sleeping participants attempted to receive telepathic information from distant senders. In a typical session, a receiver would sleep in the laboratory while polysomnographic equipment monitored brain activity. A sender, located in a separate room or building, would be given a randomly selected target image. During REM sleep, the receiver would be awakened and asked to report dream imagery. The receiver’s narrative was recorded and later presented to independent judges, who compared it to the target image and several decoy images, rating the correspondence on a scale. Statistical analysis determined whether hit rates exceeded chance expectation.

Ullman and Krippner’s early experiments demonstrated statistically significant correspondences between sender targets and receiver dream reports.¹ The use of EEG-REM monitoring was critical: it ensured that receivers were genuinely asleep and in the neurophysiological state most conducive to dreaming, eliminating alternative explanations based on conscious inference or sensory leakage. Ullman and Krippner published comprehensive accounts of their methodology and results, establishing dream-telepathy research as a legitimate experimental discipline.⁶⁹

Art-Print Transmission Studies

Building on the foundational dream-telepathy work, Ullman, Krippner, and Honorton conducted experiments in which senders attempted to transmit art prints to sleeping receivers.⁴ These studies refined the methodology further, employing multiple target images and decoy images, blind judging procedures, and rigorous statistical analysis. The art-print studies produced above-chance hit rates, suggesting that the dream state facilitated the reception of visual information from distant senders. The use of art prints (complex, emotionally evocative images) allowed for richer dream imagery and more detailed correspondence analysis than simple geometric targets.

Precognitive Dream Research

Ullman, Krippner, and Honorton also investigated whether dream content could anticipate future target material, exploring the temporal dimension of psi phenomena. In precognitive dream studies, receivers reported dreams before target selection occurred; targets were then randomly selected and presented to judges, who rated the correspondence between dream narratives and targets. These experiments produced statistically significant results, suggesting that psi phenomena might operate across temporal boundaries.²³ The precognitive findings raised profound questions about the nature of time, causality, and consciousness.

Methodological Innovation

A defining feature of Ullman’s research program was methodological rigor. Ullman and collaborators employed polysomnographic monitoring to ensure that receivers were asleep during target transmission. Ullman used blind judging procedures, in which judges rated correspondences without knowing which image was the actual target. Ullman employed randomization procedures to select targets, eliminating experimenter bias. Ullman calculated effect sizes and statistical significance, demonstrating that results exceeded chance expectation by margins that could not be attributed to random variation. These methodological standards elevated dream-psi research above the level of anecdotal reports or poorly controlled studies, establishing it as a legitimate experimental discipline.

Theoretical Integration

Beyond experimental work, Ullman developed theoretical frameworks integrating parapsychology and psychiatry. Ullman proposed that psi phenomena were not exotic violations of neurobiology but rather expressions of capacities inherent in human consciousness. Ullman argued that the sleeping brain, freed from the constraints of waking perception and rational thought, might be uniquely receptive to subtle or anomalous information. Ullman suggested that psi experiences, when they occurred in clinical or everyday contexts, should be understood not as pathological symptoms but as manifestations of normal human capacities that psychiatry and psychology had failed to recognize or investigate.⁵

Ullman’s theoretical work also addressed the relationship between psi phenomena and mental health. Ullman examined how anomalous experiences related to personality, psychopathology, and psychological well-being. Rather than treating psi as irrelevant to clinical practice, Ullman argued that understanding psi phenomena could enrich psychiatric and psychological understanding of consciousness, perception, and the nature of mind.⁷⁸

Dream Sharing and Psi Communication

In later work, Ullman explored the possibility that psi communication might occur through dream sharing, the process by which individuals discuss and interpret dreams together. Ullman proposed that the collaborative exploration of dream imagery might facilitate psi phenomena, creating a context in which anomalous information transfer could be more readily detected and understood.¹⁰ This work extended Ullman’s vision beyond laboratory experiments to potential applications in clinical and interpersonal contexts.

Comprehensive Syntheses

Ullman authored and co-authored several comprehensive treatments of dream-telepathy research and parapsychology more broadly. The monograph Dream Telepathy: Experiments in Nocturnal Extrasensory Perception, co-authored with Krippner and Vaughan, provided a detailed account of the Maimonides research program, including methodology, results, and theoretical implications.⁶ Later editions and related works continued to document and interpret the expanding body of dream-psi research.¹¹ Ullman’s theoretical writings, published through the Parapsychology Foundation and other venues, addressed the conceptual foundations of parapsychology and its relationship to psychiatry, consciousness studies, and neurobiology.¹²¹³

Influence and reception

Ullman’s dream-telepathy research established the Maimonides laboratory as the leading institutional center for experimental parapsychology in the latter half of the twentieth century. The laboratory’s work attracted international attention and inspired replications and extensions by other researchers. Ullman’s methodological innovations (particularly the use of polysomnographic monitoring and blind judging) became standard practice in dream-psi research and influenced experimental design in parapsychology more broadly.

Within parapsychology, Ullman’s work was recognized as foundational. The dream-telepathy experiments provided some of the most compelling evidence for psi phenomena available at the time, combining statistical rigor with institutional legitimacy and methodological sophistication. Ullman’s theoretical contributions, the integration of parapsychology and psychiatry, the proposal that sleep and dreaming might be optimal states for psi reception, shaped how subsequent researchers conceptualized anomalous cognition and its relationship to consciousness and neurobiology.

Ullman’s influence extended beyond parapsychology proper. Ullman’s work on dream research contributed to the broader scientific study of dreams and sleep, demonstrating that dreams could be investigated experimentally and that dream content could be meaningfully analyzed and compared across individuals. Ullman’s integration of parapsychology and psychiatry challenged the disciplinary boundaries that had excluded psi phenomena from mainstream psychology and medicine, arguing that understanding consciousness fully required engagement with anomalous phenomena.

The Maimonides Dream Laboratory remained active and productive for decades, continuing to generate experimental data and theoretical insights. Ullman’s collaborative relationships with Krippner and Honorton produced some of the most significant research in parapsychology, and the three researchers’ combined output established dream-psi research as a distinct and productive subfield.

Ullman’s legacy in parapsychology is substantial and enduring. Ullman’s dream-telepathy experiments remain among the most frequently cited studies in parapsychology, and Ullman’s methodological standards continue to influence contemporary research. Ullman’s theoretical vision, that parapsychology and psychiatry could be integrated into a comprehensive understanding of consciousness, remains influential among researchers seeking to bridge parapsychology and mainstream science. The Maimonides research program, under Ullman’s direction, demonstrated that rigorous experimental investigation of psi phenomena was possible within institutional settings and that such research could meet the methodological standards of mainstream science.

In the broader context of parapsychology’s history, Ullman represents a crucial figure in the professionalization and institutionalization of the field. By establishing the Maimonides laboratory, developing rigorous experimental protocols, publishing comprehensive accounts of methodology and results, and integrating parapsychology into psychiatric and psychological discourse, Ullman elevated parapsychology from a marginal pursuit to a legitimate scientific endeavor. Ullman’s work demonstrated that psi phenomena could be studied systematically, that experimental results could be statistically significant and reproducible, and that anomalous cognition could be meaningfully integrated into scientific understanding of consciousness and neurobiology.
