Apparitional experience

The term and research program emerged in English-language parapsychology in the late 19th and early 20th centuries. Early investigators associated with the Society for Psychical Research—notably Edmund Gurney, F. W. H. Myers and Frank Podmore—systematically collected first‑hand accounts, especially of 'crisis cases' (apparitions contemporaneous with distant deaths), motivated in part by hypotheses about survival of personality after death. Subsequent taxonomic and phenomenological work (for example by Celia Green and Charles McCreery) reframed such reports in cognitive and perceptual terms. The academic coinage 'apparitional experience' was chosen to describe apparent perceptions without committing to metaphysical explanations such as survival, telepathy, or purely pathological hallucination.

First‑hand reports historically collected indicate apparitional figures often present as visually convincing and may 'appear solid and not transparent', being realistic enough to deceive the percipient about their hallucinatory character. Most commonly a single sensory modality—vision—is involved, though other senses are sometimes reported. Content ranges widely and may include living humans, nonhuman beings, and even inanimate objects. Cases vary in emotional valence: while some reports are distressing, many percipients describe experiences that are comforting or reassuring, particularly in crisis contexts.

As described in the parapsychological literature, apparitional experiences are primarily perceptual episodes rather than agentive beings. They rarely leave ordinary physical effects (for example, footprints), and it is uncommon for apparent figures to engage in verbal interaction; most reports involve only one sense, most often vision. A subset of reports ('crisis apparitions') appear coincident with distant critical events (such as a death), which led investigators to propose telepathic or informational explanations; however, the historical research corpus has not provided conclusive evidence for telepathy or survival. Interpretive accounts within the literature range from hallucination arising from central cognitive processes to symbolic constructions of the unconscious that can convey information or meaning to the percipient.
