Who am I?

I glanced over the heads of fifty or so children as something caught my eye. It was picture. It seemed to have the same works in it that were surrounding me. I walked slowly towards the painting. My feet clicked along the bare floor. I stood in front of the exhibit. As my figure came into the picture, Hayley walked up beside me and her reflection showed up in it as well. Our motionless bodies stood staring. I raised my hand and my figure did so too. Our eyes widened every second. One minute passed when we realised it was a mirror.
