KUALA LUMPUR, Nov 5 — Ghosts and spirits have long been staples of horror films, but sometimes the most unsettling horrors come not from the supernatural, but from the cruelty people inflict on one another.

This is the central idea behind The Confessions of a Shaman.

This Thai horror-thriller directed by Natthanon Cholumpi explores grief, injustice and desperation through a story involving black magic while examining how personal suffering can drive people toward disturbing choices.

Thai horror cinema has long drawn inspiration from folklore, spiritual beliefs and occult traditions.
