Medical Diagnosis: Possession Trance
Physicians Diagnosis Manual:

DSM IV, section 300.14, pp 486-487, and i quote, "the diagnosis of
dissociative identity disorder takes precedence over dissociative amnesia,
dissociative fugue, and depersonalization disorder. individuals with
dissociative identity disorder can be distinguished from those with trance
and possession trance symptoms that would be diagnosed as dissociative
disorder not otherwise specified by the fact that those with trance and
posession trance symptoms typically describe external spirits or entities
that have entered their bodies and taken control."
Just for clarification, this means that generally a person with
trance/trance possession symptoms would be classified as DDNOS, but not all
DDNOS diagnosis are of trance/trance possession. Its just the "catch-all"
that "not otherwise defined" dissociative experiences are placed under.
