Mass possession can be just a case of mass hysteria, explainable
by psychology.
If you notice carefully, most of the cases of these so-called
mass possession always involve teenagers, women, and/ or groups of
people who are close-knit and know each other, such as friends,
classmates, or colleagues.
They are also involved in a mental conditioning which makes them
susceptible to suggestions, just beforehand. Such as praying,
ritual, visiting tomb, visiting park, or jungle. Such activities
make their mind especially open to hysteria and superstition.
So dont believe in this.
yup, especially people who know each other.
married couples and lovers displays synptoms of hysteria , and
keeps moaning and moaning when they sleep together. do listen
outside their door the next time they sleep.
