Slain in the Spirit or spirit?

I have a problem with it. It's sometimes biblically credited/ verified by 'the soldiers fell down as dead men', when Jesus said, "I am He" and at the resurrection morning but this doesn't agree with what and why I see it in church. As a sideline to this topic, I Know a pastor who feels pains in his own body and this triggers other pastors to either hold him up or 'minister' to him laying on the carpet in front of the church. This prompts a message on the screens to 'come forward for prayer in the lower back', or knee; wherever he is feeling the pain. A week or so ago he was on his back, knees bent up and when asked by the Sr Pastor what was going on, he was told he was giving [spiritual] birth to whatever, holding his abdomen as if having contractions. I've been a Christian for a very long time and tell awesome testimonies and am totally happy knowing God, but I often see performances/ experiences that I have never had, doesn't set well with my discernment (being the gift most often at work in me but am observant to the authority in the church), or I haven't found in the Word anywhere and it does not agree with the character of the God of Abraham, Issac and Jacob. More frustrating is to confront pastors and leaders and am told they admit there are some who aren't in 'order'. I guess they feel somehow stuck and lost control of their own churches, pastors, and congregants. I've been in the presence of God where it was so thick and tangible just walking through the door you knew He was there, one time feeling like it was raining, at times there is a scent - in the spirit not where you could inhale through your nose and detect it better; usually like that of oil and has walked with me for several days. I have seen visions, heard voices, prayed, prayed for others and been prayed for and never a thought or feeling to 'faint'. I am not one to see first then believe. I know what it is to be prayed for and feel that wobbling shaking inside, or a warm feeling, and a feeling of power to the point the electricity went off and back on at the mention of Jesus' name at the end of a 'good' Holy Spirit led prayer for a certain church member; happening 3x each a week apart at home. One day I mentioned to the Lord I hadn't laughed in a while which is unusual for me. I turned around and seconds later was suddenly overcome by such laughter, falling to my knees, histerical out of nowhere immediately. He knows my name - that's a song playing as I write this - "I don't have all the answers to questions in life, but I know in Whom I have believed" and He's never knocked me out. He's the lifter of my soul.
