According to Thai usage recorded by the Royal Institute Dictionary and summarized in ethnographic accounts, Phi Tai Hong arises when a person dies an unnatural, violent, or sudden death (tai hong) — for example murder or drowning — and thus cannot prepare for death or complete obligations. The suddenness/unexpectedness component is emphasized in the Thai term: victims are unable to fulfill desires or proper funerary observances, producing a lingering, vengeful spirit. Historical writings also record concerns about pregnant women who die with their unborn children; such deaths are classed as Tai Thang/Tai Thong Klom and regarded as embodying the power of two lost lives (van Vliet as cited in modern summaries). The sources note exclusions and distinctions in Thai usage: deaths by slow illness or socially anticipated deaths are not the paradigmatic condition for Phi Tai Hong (Royal Institute Dictionary summary as reported).
The supplied sources do not offer a single, consistent physical description; rather they emphasize behavior and danger. Modern popular culture (films, soap operas) frequently depicts Phi Tai Hong in visual media—often in the form of a frightening, vengeful apparition and in narratives focused on women who died in childbirth (for example the Nang Nak tradition) — but the academic and reference sources stress that the category is defined by sudden violent death and resultant malevolence more than by a fixed corporeal appearance.
Phi Tai Hong are described as vengeful and restless spirits whose anger and sorrow manifest as active malice toward the living. They are said to haunt the location of their death, can be especially dangerous and aggressive because of unfulfilled desires at death, and are often believed to attempt to kill living people in the same manner in which they themselves died. They are considered among the most feared ghosts in Thai culture and particularly difficult to exorcise; exorcisms can be very complicated and involve arcane ceremonies (all statements summarized from cited reference material).
