Goobly-woobly
Shortly after my exorcism, I went to a community church meeting. I watched incredulous as the speaker at the front whipped the crowd into a frenzy, promising that god's spirit was going to descend tonight...
Then the crowd around me started singing, in a wierd language I've never heard before... next thing I knew I was singing right along with them.
There was some excitement at this, taken as a "sign" that my exorcism had actually worked. The pastor from the local church I was going to, who had attended my exorcism, actually joining in the laying on of hands. He was very exited that I had been "blessed" with the "gift" of "speaking in tongues". He too saw it as a sign of success.
Looking back, I can see now it was just a crowd being driven into a frenzy by the excited speakers at the front. Nobody spoke in foreign languages - nor in "angelic song", as they put it. I can still speak in tongues now, though I do it for my own amusement and not because it has the slightest bit of meaning.
