Was I slain in the Holy Spirit?

I attend a Pentecostal church and I went to a Christian concert/praise group thing this weekend. On Friday, I found myself standing in front of the stage and praising God. Then the speaker called out to all the youth leaders to come in front to pray. I continued praying and suddenly, I felt a hand on my chest and a hand on my back pushing me to lay down. It felt like the hands were from the same person. At first, I did what any person would do when falling-tried to catch myself. But after stumbling a little and not being able to resist the pull, I gave in and layed down. I laid there conscious, shaking, for about five minutes. I couldn't open my eyes or stand up. Finally, I opened my eyes and sat up. Everything was bright and my ears tuned back in to the rest of the world. I then asked who pulled me down. And two of my friends said I fell down myself, without stumbling or anything. They said a woman and a man were touching my shoulder and they caught me after I fell but nobody pulled me down. So was I slain in the Holy Spirit?
