Worst timeline
I imagine sometimes that various ghosts or angels appear to versions of me in alternate realities at certain critical points in their lives. "Stop!" they exclaim, "If you keep going down this road, your life will be immeasurably worse! Here, let me show you ..." Then, they take the other me's hand and transport them to this reality.
They point to me, alone and miserable, and say, "This could be you."
