"Son, you're gonna drive me to drinkin'!"
No prob, Lincoln. I am a Christian, I do feel the gentle strength of the Holy Spirit guiding my life away from the JW cult. I started partaking almost ten years ago at the Memorial and been persecuted by the local elders for witnessing about Jesus mediatorship and being adopted as God's sons and daughters through faith in Christ Jesus.
What you are describing is a feeling of euphoria due to a heightened emotional climax, it is sort of a trance state. It can be found in many other religions and especially so animistic religions where shamans put themselves in such states as part of their rituals.
Babbling at the top of your voice and saying hah-hah-hah-hah sounds more like a shaman's trance incantation to the demons.
Remember what the fruit of the Spirit entails: love, joy, peace, patience, kindness, goodness, faith, mildness, self-control. Those are the things that should evidence a Christian's faith in reliance of anointing by the Holy Spirit, are they not?
