The "laughing revival" is an altered state of consciousness.
A similar experience has taken place in Seattle, Washington called the "Seattle Revival Center." In 1994, three pastors, Darrel Stott of Lake Boren Christian Center, Steve Richard of Freedom Life Foursquare, and Wayne Anderson of International Church traveled to Toronto and claimed they "got drunk in the Holy Spirit."
Pastor Stott tells of his legs growing weak, falling on the floor, his legs flying in the air, laughing uncontrollably, feeling like a drunk, staggering, swinging around posts, shaking, furniture flying in the room, floor rolling, twitching, yelling, rolling down the halls, etc.. ("O Timothy" - #8, 1997 - page 2-4)
I believe these apparitions are demonic. At the Lausanne II Evangelical Conference in Manila in 1989, John Wimber testified of these supposed signs and wonders. "A member of the press panel from India refuted the claim that these miracles and signs must be from God. He said that the same charismatic-styled tongues, healings, miracles, signs and wonders are also found among the heathen religions of his native India." ("Foundation" magazine - March-April, 1997 - page 13) As Quix said " And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world."
