The 1913 academic paper that coined the term 'lucid dream' and first proposed that logic and free will could coexist with deep sleep.
In 1913, the Dutch psychiatrist, poet, and novelist Frederik (Willem) van Eeden (1860–1932) published a seminal paper titled A Study of Dreams in the Proceedings of the Society for Psychical Research (Volume 26). This document is widely considered the genesis of modern oneirology, primarily because it introduced the term "lucid dream" to the global scientific lexicon. Drawing on an extensive personal diary maintained over a sixteen-year period from 1896 to 1912, van Eeden meticulously documented approximately 500 dreams, of which 352 were classified as lucid. His approach was radically empirical for its time: rather than relying on the prevailing psychoanalytic models of the era — which, heavily influenced by Freud, viewed dreams as chaotic, pathological manifestations of repressed desire — van Eeden treated the dreamscape as a legitimate arena for conscious exploration and scientific observation. The most profound theoretical contribution of the paper was van Eeden's challenge to the prevailing concept of psychological dissociation during sleep. Where the scientific consensus of the era, championed by figures like Havelock Ellis, held that sleep was a state of complete mental dissociation, van Eeden argued that a lucid dream represents a complete "reintegration of the psyche" within a non-spatial, psychical mode of existence — the sleeper fully remembers their day-life, is aware of their physical condition, and is capable of free volition and logical reflection, all while remaining physiologically paralyzed and deeply asleep. This assertion prefigured modern neuroimaging studies by nearly a century; contemporary fMRI and EEG research has confirmed that the dorsolateral prefrontal cortex — normally dormant during REM sleep — reactivates during a lucid dream. His observations on 'Demon-Dreams,' in which van Eeden found that consciously confronting hostile, mocking dream entities dissolved their terror and produced serenity upon waking, prefigure later Jungian shadow work and modern therapeutic applications of lucid dreaming for chronic nightmares and PTSD.
1. Initial Dreams
Extremely rare dreams occurring at the exact onset of sleep, with almost no loss of memory; the dreamer is aware of falling asleep and often feels a sensation of floating, free of bodily fatigue and visceral perception.
2. Pathological Dreams
Dreams directly influenced by the physical condition of the sleeper, such as fever, indigestion, or toxins, typically occurring near the moment of waking.
3. Ordinary Dreaming
The standard, universally experienced dream, characterized by dissociation, a lack of waking memory, false remembrance (paramnesia), absurdity, and faint traces upon waking.
4. Vivid Dreaming
Dreams of intense clarity and profound emotional impact that linger for days; despite their vividness, the mind remains dissociated and lacks waking logic, and they often feel premonitory.
5. Symbolic (Mocking) Dreams
Dreams with a 'demoniacal' element, appearing constructed by a low-level intelligence and relying heavily on (often erotic) symbolism where an image stands in for a waking concept.
6. General Dream-Sensations
A rare state devoid of visual imagery or events, where the sleeping mind is continuously occupied with a single abstract thought, person, or place.
7. Lucid Dreams
The state of complete psychological reintegration: the dreamer possesses full waking memory, free will, and the ability to direct attention, all accompanied by a distinct 'dream-body.'
8. Demon-Dreams
Highly specific dreams that frequently follow the collapse of a lucid state, in which the dreamer is confronted by hostile, shape-shifting entities; van Eeden found that consciously fighting these entities produced deep psychological refreshment.
9. Wrong Waking-Up
The phenomenon of a 'false awakening,' where the dreamer vividly experiences the sensation of waking up in their bedroom, entirely unaware they are still asleep and dreaming.
As the paper that formally introduced the term 'lucid dream,' A Study of Dreams is a vital and constantly cited historical reference in essentially every academic article and popular account of the field. Its central argument — that free will and high-level cognition could exist simultaneously with deep sleep — was revolutionary for 1913 and stood in direct opposition to the dissociation model championed by Havelock Ellis and the broader psychoanalytic establishment of the era. Modern neuroimaging (fMRI, EEG) has since vindicated van Eeden's core hypothesis, showing that the dorsolateral prefrontal cortex reactivates during verified lucid dreams. Van Eeden's granular nine-part taxonomy of dream types, and his early observations connecting conscious confrontation of hostile dream figures to psychological refreshment, are recognized as prefiguring both cognitive dream science and Jungian shadow work by decades.
“For my part, it was just this form of dream, which I call 'lucid dreams,' which aroused my keenest interest and which I noted down most carefully.”
“The dream is a more or less complete reintegration of the psyche, a reintegration in a different sphere, in a psychical, nonspatial mode of existence.”
Dutch psychiatrist Frederik van Eeden coined the term in his 1913 paper A Study of Dreams, published in the Proceedings of the Society for Psychical Research.
He argued against the prevailing theory that all dreams are states of mental dissociation, proposing instead that lucid dreams represent a 'reintegration of the psyche' where free will and logic are fully restored during sleep.
This was van Eeden's term for what modern sleep science calls a 'false awakening' — a highly convincing dream wherein the subject believes they have woken up in their actual bedroom.
He firmly rejected somatic theories of dreaming, maintaining that the physical condition of the sleeper (digestion, bodily discomfort) had almost no influence on the content of true dreams, aside from specific 'pathological' dreams.
