P
Peripheral Motion Event — Brief, flicker‑like movement perceived at the edge of vision with no corresponding physical source. (Associations: Visual anomaly; shadow subtype; liminal architecture.)
Phantom Touch Sensation — Light pressure, brushing, or tapping felt on the skin without physical contact. (Associations: Somatic anomaly; presence cue; proximity impression.)
Photonic Drift — Slow, wandering movement of small light points or glimmers within a space. (Associations: Visual anomaly; light interaction; low‑intensity manifestation.)
Presence Compression Field — Sudden tightening or constricting sensation around the witness, often accompanied by atmospheric heaviness. (Associations: Somatic anomaly; presence phenomenon; pre‑event indicator.)
Pulsed Sound Event — Rhythmic, heartbeat‑like auditory pulses with no mechanical or environmental source. (Associations: Auditory anomaly; EM correlation; environmental shift.)
Q
Quasi‑Apparitional Form — Partial or incomplete figure that lacks full coherence, often appearing blurred, translucent, or fragmented. (Associations: Visual anomaly; apparition subtype; low‑clarity manifestation.)
Quiet Zone Phenomenon — Sudden, unnatural drop in ambient sound levels, producing a sense of auditory “vacuum.” (Associations: Environmental anomaly; presence cue; pre‑event indicator.)
Quotidian Loop Event — Repetition of a mundane sound or action (footsteps, doors, voices) that mimics everyday activity but has no physical source. (Associations: Environmental repetition; auditory anomaly; archival sites.)
Quiver‑Shadow Effect — Rapid, trembling movement of a shadow form without corresponding light fluctuation. (Associations: Shadow phenomenon; visual anomaly; liminal spaces.)
R
Residual Energy Pattern — Perceived emotional, atmospheric, or sensory “imprint” linked to past events or repeated historical activity. (Associations: Environmental anomaly; historical residue; interpretive overlay.)
Responsive Knock Sequence — Knocking or tapping that appears to answer or mirror witness actions or vocalizations. (Associations: Auditory anomaly; responsive pattern; corridor or cellblock alignment.)
Room‑Scale Temperature Drop — Sudden, uniform cooling of an entire room without environmental cause. (Associations: Temperature anomaly; environmental shift; high‑intensity event.)
Receding Footfall Event — Footsteps that audibly move away from the witness despite no visible movement or physical presence. (Associations: Auditory anomaly; directional cue; corridor‑linked.)
Refractive Light Distortion — Bending, warping, or shimmering of light within a space, often appearing as heat‑haze without a heat source. (Associations: Visual anomaly; environmental interaction; rare.)
