I am a minister too.
The Bible doesn't say much about this phenomenon not because it is "not biblical", but because we are not to focus our attention on it. We are to focus our attention on the LORD.
I come from a home that didn't go to church at all. My wife - Muslim. But in our own living room the Holy Spirit showed up! Everyone was slain in the Spirit. There was no music - no hype and NO psychological manipulation.
Needless to say - my family is now a church going family. My wife (after getting slain in the Spirit) turned from Islam and gave her life to Jesus!
Today our home is filled with the presence of God like never before. Surely when the Holy Spirit come, good fruit is the result. Glory to God!
In response to the former comment: 1. When the Holy Spirit shows up there is always a show. Creation was a show. Moses on Mt. Sinai was a show. Jesus walking on water was a show. etc...etc... etc... Just because you see "a show" doesn't mean its bad, and it doesn't mean its not God.
Finally, the "false prophet" label is way too overused in Christian circles. Do "false prophets" flow in the true power of the Spirit of God? Do "false prophets" produce good, and Godly fruit? The answer:NO. See my hub on "Is it Really God"
