Was It My Imagination Or Was It Actually Michael?

Okay guys, im gonna tell you something...but I don't know if it's real or not...please don't call me crazy because im still trying ot figure it out myself. So I was over my friends house yesterday and we are both BIG MJ fans. You see she has 5 posters of him on her walls. We were online and saw this little prayer that helps you talk to spirits. She told me to get candles so we could talk to Michael's spirit. We lit up the candles and put them in a small circle in the room, in the middle of the circle we put a picture of Michael. My friend and I sat on the floor holding hands, I was too scared to say the prayer so she said it. After she said it everything was quite,then the candle lights went out. The room was dark, we heard a couple of noises. We both freaked out so we ran out of the room screaming. After a couple of minutes we went back inside and into our suprise all of her MJ posters were almost falling off the wall, they were folded a little and some were ripped. What the heck happened? I told my brother and he called me crazy and that im over-reacting but I know what I saw! Someone please explain to me...what happened?
