Vision? or revelation?

Earlier today, I was in church. It was the end of the ceremony, and we were finishing up with a prayer. As we all prayed (about 2,000 people) so it was one person presiding, but anyways, during the prayer my eye's were closed, and while I was listening. I felt my butt hit a concrete sidewalk. I opened my eye's and I was physically somewhere else. I was sitting on the side walk next to a very tall tan sky scraper, and there were two people playing around, which in the instance I got the notion that they were my friends and they were about five feet away from where i was sitting. One of the kids was an African-American, and the other Asian-American, both looked about early 20's. I am only 15 right now. But I when I was there I felt the warmth of the sun and the drift of the wind. I could feel the concrete under my but and heels. The two kids mentioned before, the black one took the asian ones' hat and the asian was jumping and trying to get it back. they were just playing around and laughing. they both spoke english. and dressed how I do now. The african was wearing a backpack. and I noticed that we were in a big city. nobody else was there and I didn'tt talk to anyone. I had this overwhelming feeling of suprise so i didn't say anything, but the experience only lasted about 5 seconds this is all i remember. But I would like to know if anyone knows what this means. thank you, and I wanted to remind you that i WAS physically there It was not a dream and it didnt feel anything like it. P.S. when I came back to the prayer and into my same seat. I had the feeling of being moved, i was not moving but i was being moved back into my seat.
