This is the danger of the power of the Mob. When people get together in large groups, they can be induced to act in ways they would not when alone, powerfully moved to feel and think things that are often quite irrational and - in some tragic cases - very destructive. What I suspect you felt wasn't the Holy Spirit but the psychological effect of the Mob (or group, if you prefer) disposing you toward an unusual experience that the leaders of the Mob, using the power of the Mob mentality, were urging you to expect. There is a reason why the person writhing about on the floor in a so-called "spiritual ecstasy" only has such experiences at revival meetings and weekend conferences, usually in careful isolation from any dissenters, where everyone is confirming and encouraging the individual person to indulge any wild impulse that takes them. Very fleshly, very demonic stuff, sister. Beware!
In the record of Scripture, we can read of many ways in which the Spirit acted: convicting people, empowering them, illuminating their understanding, comforting them, and even disciplining them. Being the HOLY Spirit, his chief work however is to make you and I
holy, confronting us about our sin and urging us toward a life more and more set-apart unto God. To this end, when the Spirit "moves" upon the Church, conviction of sin, not feelings of warmth or electricity, or bizarre, uncontrolled behavior are the result. But people laughing hysterically, or chanting as you've described, or crying uncontrollably don't want changed lives, holy lives set apart from the World, the Flesh and the devil; they want sensual experiences, sensational moments, stimulating events.
Sensual Faith: Oh, God, You Make Me Feel Sooo Good!
Amen! Exactly. Craziness is not listed among the Fruit of the Spirit. If, though, you remain in the company of people telling you that this is not so, that craziness is a normal part of spiritual living, eventually you will conform to their influence. Peer pressure is a very potent thing.
Actually, God judges and disciplines by giving people what they want without His constraint upon them. He has warned that falsehood and sin always, sooner or later, produce death - death of fellowship with Him, death of joy, of peace, of contentment, of inner stability, and so on. When people insist on following false and sinful ways, God uses the bitter consequences of these things as the means of His discipline.
Read Romans 1:18-30 (or so).
