...spirit of the Holy Ghost moves? through everyone present? It's truly an amazing experience and I doubt you would keep disbelieving in our Lord after that experience.
A person might think it means something if they didn't know a thing about psychology. Or realize that ecstatic states are achieved in many religions and superstitions, including shamanistic rituals of tribes.
I am a Christian, but this is a horrible question to ask. Are you expecting a "yes! I think I'll become a Christian!" or rather are you expecting a "that happens?? wow! cool! sign me up!"
