Apparitional experience

Reports stretch back centuries. The few collective and 'crisis apparition' cases are intriguing; controlled study is essentially impossible.

Reports stretch back centuries and across every culture. Most well-investigated cases reduce to pareidolia, infrasound, expectation, or fraud; the broader 'soul of the dead' reading is essentially unverifiable.

Most reports happen at sleep boundaries or in peripheral vision — exactly where the brain is most prone to producing humanoid silhouettes. The 'external entity' reading is a much larger claim.

Evidence around dying, near-death experience, and what (if anything) continues.

Whether anything of mind continues.

Telepathy, precognition, remote viewing, PK.

Reports of contact with the deceased.

Psychedelic, contemplative, out-of-body experience.

Cryptomnesia, anoxia models, cold reading. Counter-anchors.

Catch-all reference for the broad ghost claim; pair with apparitional-experience and parapsychology entries for the specific phenomenology and lab-history strands.

Useful for both the phenomenon's claims and the well-developed sceptical literature.

Useful general-audience anchor for psi-related claims; gives both the field's self-description and the standard sceptical critique.

Direct reference for the shadow-people claim; pair with sleep-paralysis and apparitional-experience entries for the underlying mechanisms.

Single most-cited mechanism behind shadow-people sightings, bedroom visitations, and many folkloric night-encounter traditions.

Important for apparition and ADC pages because it shows how common bereavement-related perceptions can be without requiring a paranormal interpretation.
