The blank Screen and the unmade Sandwich

"I was in a hotel room with someone and I don't know who. That's the honest part. I just knew I wasn't supposed to be there, and I wasn't even doing anything. We were just sitting on the bed watching TV. Then my girlfriend texted me. The phone was in my hand but the screen was blank and I knew it was her anyway. Just "where are you" and I typed "almost home" and put the phone face down. The other person was gone. No leaving, just gone. The room was ours now, mine and hers, except the furniture was arranged wrong. I kept trying to fix the couch. She was in the bathroom running water for a really long time. I wanted to explain but there was nothing to explain. Nothing happened. I kept saying that in my head. Nothing happened, nothing happened. She came out and said "it's fine" and made a sandwich. I watched her cut it in half. I woke up guilty and had to lie there for a minute reminding myself it wasn't real. Then I went and made us coffee. Two cups. Normal morning. Nothing happened."
