Dream

I'm sitting in a subway car. Sun is pouring in through the windows. We're above ground. I'm reading, but notice something moving on the floor from the corner of my eye. It's a dove. It's injured. I watch it writhing on the floor. It looks like something invisible is choking it. I'm horrified and I try to call out for help but everything is completely silent, including my voice.

The bird dies as I watch. No one notices but me.
