Real?

It happened again. It's been happening all day. I can't make it stop.
Turn up the music to tune them out.

"I fought the war. I fought the war. I fought the war, but the war won't stop for the love of god!" -Metric screams in my ears...
And I believe her. I am now fighting the endless battle that consumes my mind.

I doubt the existence of the people I've been talking to. I doubt my setting. I doubt my sanity. I doubt my insanity. I doubt my words. I doubt sounds. I doubt patterns... But I believe patterns. Patterns remind me I'm alive. Patterns bring me back. Patterns distort my perception. And suddenly I'm lost again.

Time is altered. It doesn't apply to me. I am not in this space and time. I'm in my own. This is my world. My universe.

What is reality? What is it? What is real?
