Pasatsats are ghosts of people who died or were killed in the Second World War.
Etymology
Pasatsat is word rooted on the Pangasinense word satsat, meaning to stab.
Origin
Coffins during the time were so expensive, so the families of the dead wrapped the corpses in reed mats or icamen. The dead were buried in places other than cemeteries because tomb robberies were rampant during that era of extreme poverty.
Behavior
These ghosts usually show up in solitary paths and block passersby. To get rid of such a ghost, one needs to stab (hence pasatsat) the reed mat and unravel it, but doing so will show no presence of a corpse, although the mat will emit a noxious odor, much like that of putrid flesh.
