Astral Definitions
A glossary with teeth
Words are doing too much work on the internet. “Astral projection,” “out-of-body experience,” “lucid dream,” “sleep paralysis,” “soul flight,” and “the phase” are not one phenomenon with five costumes. This page is a glossary you can actually use. Define first. Then compare.
What this page establishes
- OBE is the laboratory term: a phenomenological report of the self located outside the ordinary body.
- Astral projection is a practitioner tradition and a set of methods, usually carrying an interpretation.
- Lucid dreaming, sleep paralysis, and “the Phase” are neighboring states with different definitions.
- Kinship labels (predecessor, analogue, shared phenomenology, distinct phenomenon) are claims about relationship, not compliments.
- Evidence status
- Glossary. Definitions are stipulated so comparison can be done without theft of terms.
Out-of-body experience (OBE)
In laboratory English, an out-of-body experience is the impression that the self is located outside the physical body, often with a view from somewhere else — the ceiling, the doorway, a few feet away. Blanke’s group and later reviewers use that phenomenological core. It does not require a traveling soul. It does not forbid one. It is the term this archive prefers when discussing experimental work, because it is the term the papers use.
That definition is deliberately thin. It names a report so papers can be compared. It does not settle what the report means. A person can have an OBE in a hospital chair, in bed at 3 a.m., after an accident, or after a method they practiced. The setting is not the definition.
Astral projection
A modern esoteric and popular term. It thickened in Theosophy and late-nineteenth-century occultism — “astral body,” “astral plane,” a geography of the unseen — then traveled through twentieth-century how-to books and internet practice. It usually carries an interpretation: a subtle or “astral” body leaves, travels, and may perceive. That interpretation is not entailed by the OBE report. You can have the impression of being outside the body without believing in planes. You can believe in planes without having the impression tonight.
On this site, “astral projection” names a practitioner tradition and a set of methods. When we say it, we mean the culture and the techniques, unless we explicitly say otherwise. The word itself is a European occult export. It is not a translation of milam or of Harner’s “journey.”
Lucid dreaming
A dream in which the dreamer knows they are dreaming, sometimes with partial control. Stephen LaBerge demonstrated signaling from the lucid state in 1981: agreed eye movements from REM, so lucidity is not only a morning story. Later work (Voss and others) describes hybrid REM-wake physiology.
Lucidity can coexist with an out-of-body narrative (“I left the body inside the dream”). That coexistence is not identity. A lucid dream is defined by insight into the dream. An OBE is defined by a change in the felt location of the self. They overlap. They are not synonyms. See Sleep.
Sleep paralysis
REM atonia — the normal paralysis that keeps a dreaming body from acting the dream — persisting into, or colliding with, wakefulness. Immobility, often with fear, pressure, buzzing, or a sensed presence. It can precede, follow, or be mistaken for an OBE. It is not, by itself, “getting stuck out of body.” Naming it in advance is a safety act: remember you named it, breathe, wait, sit up when you can. Recurrent, impairing paralysis belongs with a clinician, not with a stereo generator.
The Phase (Raduga)
Michael Raduga’s umbrella for lucid-dream, OBE, and sleep-paralysis-adjacent states treated as one trainable “phase” of consciousness. Useful as a practitioner taxonomy — a map of neighbors. Dangerous if it erases distinctions the lab still needs. This archive will not publish “three days” as a guarantee. It will attribute the three-day frame to Raduga’s training claims and leave it there.
Hypnagogia, hypnopompia, false awakening, vibration
Hypnagogia is imagery and sensation at sleep onset: geometry, voices, a face too close, a sense of dropping. Hypnopompia is the same family at waking. Practitioner manuals often call this “the gate.” Sleep science calls it a normal edge process. Content is not automatically a place.
False awakening is a dream of having woken. Nested rooms. A light switch that does nothing twice. Keep a physical test if you care about the distinction (read text twice; check a switch). Tests are fallible. Notes still help.
Vibrational / buzzing / roaring reports are common in practitioner literature at the sleep edge. They have candidate physiological stories (inner ear, muscle atonia, hypnagogic sound) and practitioner interpretations (energy, separation). This page records both. It does not pick a winner in the glossary. If vibration spikes into panic, sit up.
How this archive labels kinship
When a tradition is placed next to modern astral-projection culture, we use one of these labels. We do not silently translate. Each label is a claim about relationship, not a compliment or an insult.
- Direct predecessor — a later practice actually inherited the word or the recipe. Example: Theosophy’s “astral plane” is a direct predecessor of the internet’s word “astral.”
- Historical influence — later writers read an earlier book and worked in its shadow, without being a copy.
- Conceptual analogue — similar questions, different ontology. Example: a Daoist spirit that can leave, or Wīrāz sent to see and return. The idea that a person is not only the visible body, without a shared theory.
- Shared phenomenology — similar first-person motifs (flight, a double, a tunnel, buzzing, paralysis) without shared explanation.
- Shared practice — similar methods (rhythm, darkness, visualization, waking in the night) without shared ends.
- Modern reinterpretation — a later writer rereads an older tradition as if it had always been “astral projection” or “core shamanism.”
- Distinct phenomenon — do not flatten. Purpose and worldview stay with the source. Tibetan milam is the standard example.
If we cannot answer “what did the original culture mean?” the page is not ready. That is the quality-control rule for the Atlas.
