The energy and non-corporeal entity category encompasses reported intelligences that appear to lack a fixed biological or mechanical body — entities that manifest as light, electromagnetic fields, energy patterns, shadows, or non-physical consciousness structures. These phenomena bridge the physical sciences, parapsychology, and ontological philosophy: they are among the most frequently reported anomalous entities worldwide yet remain the least tractable to conventional scientific frameworks. The category is unified not by morphological similarity but by the apparent absence or irrelevance of physical substrate: whatever these phenomena are, they do not appear to be made of matter in any straightforward sense.
Across the reported phenomena gathered here, several properties recur as markers of the non-corporeal type:
Self-organising energy-life forms — hypothetical organisms whose structural and reproductive basis is electromagnetic or plasma field organisation rather than biochemistry. The most speculative sub-type; grounded in documented anomalous atmospheric phenomena and theoretical plasma biology.
Luminous humanoid or formless entities reported across NDE, OBE, DMT, and contact experiences. Distinguished from orbs by their apparently humanoid or quasi-humanoid character and the consistent report of benevolent, communicative intent.
Structured plasma phenomena — ball lightning, Hessdalen lights, Marfa lights, and atmospheric electrical manifestations — that exhibit responsiveness, apparent intelligence, and behaviours inconsistent with known plasma physics. The most physically documented sub-type.
Autonomous spherical luminous objects ranging from centimetres to metres in diameter, exhibiting purposeful movement, colour change, and in many accounts apparent responsiveness to human attention. Among the most photographic-evidence-rich categories in anomalous phenomena research.
Three-dimensional dark silhouettes occupying physical space independently of ambient light — including the widely-reported Hat Man figure. Cross-cultural, cross-temporal, reported by children before cultural exposure, and associated with measurable physical effects in documented cases.
Beings encountered in out-of-body, near-death, and deep meditative states — the intelligences of the non-physical or subtly-physical planes described across spiritual traditions and increasingly investigated through OBE research and the Monroe Institute's protocols.
Entities proposed to originate from or primarily inhabit dimensions of reality beyond three-dimensional space-time — as developed by Vallée, Keel, and others. Phenomenologically distinguished by their apparent ability to appear and disappear from our reality at will and their apparent purposeful management of perception.
Several theoretical positions attempt to account for the non-corporeal entity category within scientific or scientific-adjacent frameworks:
This section presents documented phenomena and theoretical frameworks without endorsement of any specific hypothesis. All entity descriptions represent reported encounters and researcher categorisation rather than confirmed physical data. No ontological conclusions are made herein.
