UAP-CDS

Contact Depth Scale

16 items across 4 categories measuring phenomenological depth of UAP contact experiences. Score range 0–32. Structurally parallel to the Greyson NDE Scale.

Purpose

The UAP Contact Depth Scale answers: "What happened?"— not "is it true?" (ESS) or "how did it change you?" (CTI). It is deliberately modality-agnostic — scoring the depth of the reported experience regardless of whether contact occurred physically, in a dream, during meditation, or through an ambiguous altered state.

A vivid bilateral dream contact can score higher than a distant physical sighting. This is intentional — the CDS measures depth of the experience as reported, not physical proximity.

The 16 Items

Each item scored: 0 = Not present, 1 = Mildly/ambiguously present, 2 = Definitely present

CD-1

Observation & Physical Encounter

Whether something anomalous was perceived, what form it took, how close it was, and whether it left physical traces.

CD-1a

Anomalous Perception

Did the witness perceive something anomalous?

0No anomalous perception described
1Vague or uncertain impression
2Clear anomalous perception — specific object, entity, or event described
CD-1b

Structured Form

Was a distinct structured form observed?

0No distinct form — only vague feelings or intuitions
1Partial form — basic shape but lacking detail
2Structured form — craft with geometry, entity with features, or geometric patterns
CD-1c

Proximity

How close was the encounter?

0Distant or no spatial proximity
1Moderate proximity — overhead, within a few hundred feet
2Intimate proximity — face-to-face, physical touch, inside craft/environment
CD-1d

Physical Effects

Were there physical effects on the witness or environment?

0No physical effects described
1Subjective sensations — tingling, heat, vibration, paralysis
2Observable or persistent effects — marks, equipment malfunction, ground traces, missing time
CD-2

Entity Interaction

Whether a non-human intelligence was perceived and the depth of interaction.

CD-2a

Entity Perceived

Was a non-human entity or intelligence perceived?

0No entity perceived — only objects or phenomena
1Ambiguous — felt presence, sensed intelligence, vague dream figure
2Clear entity — described with features, apparent agency, identifiable source
CD-2b

Bilateral Awareness

Did the entity appear to acknowledge the witness?

0Entity did not appear to notice the witness
1Entity seemed to orient toward or respond to witness
2Entity directly addressed, approached, or demonstrably responded to witness
CD-2c

Communication

Was information exchanged?

0No communication of any kind
1Ambiguous — vague impressions, unclear transmission
2Explicit communication — specific messages, information download, detailed visual imagery
CD-2d

Transportation / Immersion

Was the witness taken somewhere or immersed in an environment?

0Witness remained in their normal environment
1Partial displacement — different perspective, partial vision of another place
2Full immersion — aboard craft, different realm, immersive environment
CD-3

Consciousness Alteration

How the witness's state of consciousness was affected during the encounter.

CD-3a

Altered State

Was the witness's consciousness altered?

0Normal waking consciousness throughout
1Mildly altered — heightened awareness, time distortion, focused attention
2Significantly altered — trance, dissociation, OBE, complete shift in perceptual reality
CD-3b

Telepathic / Non-verbal Contact

Was non-verbal or telepathic communication experienced?

0No telepathic or non-verbal contact
1Possible telepathy — felt understanding, vague knowing
2Clear telepathy — specific thoughts received, bilateral mental communication
CD-3c

Time Anomaly

Were there anomalies in time perception?

0Normal time perception
1Mild distortion — time seemed faster or slower
2Significant anomaly — missing time, time slip, simultaneous perception of past/future
CD-3d

Expanded Awareness

Was there an expanded or non-ordinary perception?

0Normal perceptual range
1Mildly expanded — heightened senses, seeing energy, unusual clarity
2Significantly expanded — panoramic vision, cosmic awareness, perceiving multiple dimensions simultaneously
CD-4

Transcendent Elements

Whether the experience included transcendent, numinous, or reality-shifting elements.

CD-4a

Ontological Shock

Did the experience fundamentally challenge the witness's understanding of reality?

0No paradigm challenge described
1Mild surprise or confusion about what was experienced
2Profound ontological shock — fundamental questioning of reality, deep existential impact
CD-4b

Numinous Quality

Did the experience have a sacred, awe-inspiring, or deeply meaningful quality?

0No numinous quality described
1Mildly awe-inspiring or meaningful
2Profoundly sacred, numinous, or awe-inspiring — described as the most significant experience of their life
CD-4c

Emotional Overwhelm

Was there intense emotional response during or after the encounter?

0No significant emotional response described
1Moderate emotional response — fear, wonder, excitement, unease
2Intense emotional overwhelm — terror, ecstasy, profound peace, complete emotional transformation
CD-4d

Pattern / Recurrence

Is this part of a larger pattern of experiences?

0Isolated, single event
1Some indication of related experiences or prior anomalous events
2Clear pattern — recurring contact, lifelong experiencer, multiple encounters across years

Design Decisions

Modality-agnostic by design: Dream and meditation contacts are scored identically to physical sightings. This captures depth of experience regardless of physical reality.
Not a truth detector: A high CDS score means the experience was phenomenologically rich and deep, not that it actually occurred as described.
Video as unit of analysis: If a speaker describes multiple encounters, items are scored based on whether that feature appeared anywhere across all described experiences.
