i've been possesed before. it was kind of fun. in the kingdom hall too ... i was laughing and screaming and i couldn't stop myself. the intensity i felt was painful...they had to carry me out because i was disrupting the meeting.
it all stopped when i put up a fight. it tried to make me do stuff...i resisted...it hurt like hell...but after a while i gained control. half of it was due to my OD-ing on my meds, but half was real...i know it was. it continued even after the meds wore off until i fought it.
i can tell the whole thing in dirty detail...it scared me at first, but now i'm just glad it's over.
