Mirrored reality (part 1)

I still don’t know why it happened, but one moment I was looking at myself in the mirror, and suddenly I was inside the mirror looking at what I can only call my realself. I had lost control of my body, I was doing whatever my formerself was doing. I was no longer real, I was just a reflection of myself. My formerself was acting as if nothing had happened, and I was trapped, doing exactly what he was doing.
