how to disappear completely and never be found

It was sometime in the evening last night that I started feeling like I wasn't real anymore. I was at a show, watching the crowd between sets, and felt this weird sort of disconnect, like maybe I was imagining the whole thing--just a passing ghost that nobody could see or, worse, nobody cared about. I knew I wasn't, of course, but then there's that whole question: what if I'm wrong?

As I made my way to the bus stop I suddenly felt very ill and very weak, without any real prompting. I staggered into a seat and watched the empty 1 am streets, coughing occasionally, trying to fight off the sickness in my gut, the dreamlike certainty that the bus driver wouldn't even stop for me.

I heard a siren down the road, and I remember this very clearly, like it was a scene from a movie. A car sped past, going perhaps sixty miles an hour in the narrow downtown streets. The wind from its passing blew a bus transfer from the sidewalk, swirling it up and onto the ground at my feet. I stood up and looked down the road, where a police car was fast approaching, weaving past a few cars. I put a finger in my ear so the siren wouldn't deafen me and wondered if he saw me, if he was coming for me. I watched him drive past before I realized of course not, I wasn't really even here.

There was a crash down the road. Someone yelled something about it, but I wasn't listening anymore.
