What does this dream mean?

I had a dream last night that me and my best friend went to a chorus concert at her school (I don't go to her school), and we were on stage, and the curtains opened, and we were singing Amazing Grace, but then I forgot the lyrics, so we had to start over, and when we started over, we started singing, and then the front of the stage caught on fire. At first we didn't do anything about it, but I didn't want the fire to spread and harm us, so we went off the stage through the back door, and somehow, it took us to this tattoo parlor, and then my best friend really had to pee, so we went down to the bathroom, and it was all like, flooded with dirty water. Like, with pine needles and stuff in it, and on the door frame and all over the wall of the bathroom, was pictures of us,growing up together, and we were looking at them, and then it ended. Does this mean anything?
